    removed one bulb, still the same intensity ?

    Correct. Plants do not have eyes, they have mechanisms that operate using quantum electrodynamics and cannot be fooled. These mechanisms respond to the rate and quantity of photon bombardment per unit area. This is called "Photon Flux Density". Each chlorophyll molecule is exposed to this...

    Algae, Cyanobacteria and Plants - An Hypothesis?

    Karl, These are excerpts from messages from the venerable website The Krib A lot of the data is from the experiments of Paul Sears and Kevin Conlin. These guys were great and they brought us the original Poor Man's Dosing Drops (the first D in PMDD actually is the first letter in a...

    Spray bar or not?

    Well, as discussed, it is the sum of all things that you do that result in success or failure. Since we do not have either an image or a sketch of your setup it's difficult to assess the effectiveness of your flow/distribution. The lighting is actually not that difficult to manage if it is LED...

    Spray bar or not?

    Hello, According to the specs, the Fluval 106 is rated at 550 LPH, which is near enough the 10X rule to be muscular enough for a 60L tank. It's not clear from your post whether you had been using a spraybar with the 106. If not, why not try a spraybar before spending more money? Perhaps...

    How to read spectrum curve ?

    The best way to interpret a spectrum curve is to imagine turning it upside down and that the outline of the curve is the outline of a bucket. The bucket holds colored water. The color of the water is based on the wavelengths. To the far left is violet. From about 300 to 400 is blue. From 400...

    What to test for?

    Hello, This is definitely a CO2 related algae. Having a CO2 injected tank does not make the tank immune to CO2 shortfall. In fact, MOST problems that occur in a CO2 injected tank are actually CO2 related. There are many ways to cock up CO2, including excessive lighting, as already...

    Some plants getting black spots and small holes

    Hello, Black spots and holes, if not a result of predation, is caused by poor CO2. If this is a Co2 injected tank then review your CO2 technique. If this is a non-CO2 injected tank then the cause is related to excessive lighting - and this is the only variable that can be realistically...

    Should I remove my reflectors?

    When CO2 is exhausted and when it cannot be replenished immediately then simply turn the lights off and keep them off until CO2 becomes available again. That part is easy. It's when your lights are on that the problem is at it's most severe. Well, yes, this is simply the result of a geometric...

    Should I remove my reflectors?

    It would be ideal if you could temporarily re-house the shrimp if there are uncertainties. Glutaraldehyde has various toxicity depending on the species involved. Some plants don't like it either, while others do really well. The problem with using it properly in this scenario is that you cannot...

    Should I remove my reflectors?

    If the unit is inoperative with a single bulb then it may be necessary to find some other way to obfuscate the light so that less energy penetrates the water. This can be accomplished by using a darkened Perspex strip or other obstacle. The problem with BBA is that it is probably the most...

    Cryptocoryne pink flamingo not growing much

    CO2 is not a pill for the tank to swallow when problems arise. It is a completely different process, is complicated and brings with it a host of problems. I would be very cautious about "...getting some CO2.." as this can cause more troubles than it solves. Cheers,
  12. ceg4048

    Should I remove my reflectors?

    Yes, this is excessive, at least until the plants are stronger and/or are receiving the appropriate amount of CO2. BBA is caused by poor CO2 relative to the amount of light. It would serve better to remove one bulb for now. Yes, deformation and any other structural fault in plants is caused...

    Discus

    There are no limitations regarding the type of plants that can be used in a discus tank. The rules for keeping discus healthy coincide with the rules for keeping plants healthy. That means large and frequent water changes. What may be problematic is that you'll need careful attention to CO2...

    Is it high light ?

    This is another misconception that traps hobbyists into a never ending struggle. Difficult plants are difficult NOT because they require high light. They are difficult because they require high CO2. If you use high light without paying careful attention to CO2/flow/distribution you will face a...

    New to CO2

    When we add CO2 we are not concerned about limiting pH swing. Too many hobbyists worry about pH without fully understanding what this measurement actually is and they waste a lot of energy trying to control it. An insight into pH is provided the post=> Unlimited nutrients using E.I. The reason...

    Is it high light ?

    Hi, Yes, that sounds like a good plan assuming the fixture still functions with a bulb disabled. Cheers,
  18. ceg4048

    Is it high light ?

    Yes, but forget about lumens. Plants do not see lumens. They sense the world only in terms of PAR. In any case, 48 watts of T5 over a 10 gallon tank is completely over the top. Just disable one bulb and you'll give yourself more margin of error. Cheers,

    Mix manure and soil ?

    I suggest that you avoid manure until you have more experience. Decomposing manure releases high levels of ammonia. You do not need to worry about the soil you have. Just carry on with it. Cheers,

    New to CO2

    The DC does not care what the KH of the tank water is. As long as you are using only 4DKH water in the DC whatever pH it registers will be a direct reflection of the CO2 concentration in the tank water. The ability to dissolve CO2 in water is independent of KH. Cheers,

    What would trigger algae to grow on glass?

    Hello, Algae in planted tanks is always caused by too much light and either not enough nutrition or not enough CO2. The typical algae on glass is Green Spot Algae (GSA) which appears, as the name implies as groups green spots. Algae forms on hardscape because it is easier for them to...

    New to CO2

    Hello, The best metric is the condition of the plants and the health of the fish in the tank. It's not worth losing sleep over bubble rate. This only means that you will have to refill twice as often as you had planned on. In any case you can always reduce the bubble rate and then...

    Reducing pipe size

    This is not really true. There is a massive impact of flow throughput when reducing the cross sectional area of piping. The cross sectional area of the 16mm pipe is about 200 sq. mm. That of the 12mm pipe is just over 100 sq. mm. The flow will be proportional to this area, so that is a...

    New tank care and maintenance regime feedback needed

    Hello, A daily water change is not really necessary. A 2X-3X per week is all you need. No idea what "EA complete liquid plant food" is but you should ensure this product actually has, in fact NPK plus micronutrients. Always be wary of commercial fertilizers claiming to be "complete"...

    Mineralising soil in Scotland

    Exactly. There are no free lunches. Also, fun fact, the same bacteria you need in your sediment and filter can be found next to any weed in your garden, so just grab a handful of the dirt ball and mix in with your mineralized project sediment. Another option is to go to you local LFS and ask for...

    Hi, Or, for those annoying folks who are terminally impatient (no names, but you know who you are!), at step 3. they can mineralize by baking their John Innes #3 in an oven for 1 hour at 400-500Deg.F, or by boiling it for 10 minutes. Then they can let it cool and have their soil ready for...

    CO2 used Database -needs your data

    As Zeus mentions, we really try to discourage folks from using the pH/KH/CO2 chart because it has caused so many problems for hobbyists, mainly due to their lack of understanding of the nuance and function of the data in the chart. So there is no guide, per se, only some explanation of what the...

    How would you position 3x lilly pipes outflow/inflow running on 3x canister filters ..Staghorn and bba comming back.

    Hi erwin, Yeah, getting nice even flow to the substrate really does require the combined effort of all the outputs to push the water across and then down, regardless of what type of output. Robinj above in post #22 mentions a desire for laminar flow, but that is only true when the...

    How much nitrate NO3 does Hemianthus micranthemoides need

    Hello, As mentioned by Michael, nitrate does not cause algae. Algae do not really care how much nitrate is in the water. Lack of nitrate, however, does cause algae. The Eurozone limit for NO3 is 50ppm, so no, tap water does not very often have zero nitrate, and for our purpose, does not...

    How would you position 3x lilly pipes outflow/inflow running on 3x canister filters ..Staghorn and bba comming back.

    Hi, No, this rarely, if ever, happens. The reason is that the water comes out of the pipe as an expanding cone. The cones from each direction then collide and typically cause cancellation. This weakens the flow from each direction. It is always better to have all pump outlets on the same...

    Yes, ferrous gluconate is a popular addition used as a component in some commercial mixes as well as in DIY mixes, but you're only adding small amounts to raise the iron by fractional amounts, like 0.4ppm. But no, as mentioned, plants cannot use this carbohydrate. The Rubisco molecule only...

    Suspected lighting issue

    Always suspect poor CO2. You'll have a better than 90% chance of being right. As X3nith mentions, adjust the flow. As the plants gain more mass they require more CO2 and at the same time they are blocking each other by their growth. You may require a more robust flow technique to ameliorate...

    Hi Michael, Well, you maybe can get an idea of the amount of CO2 dissolved in the same way as the pH profile by looking at the difference in the CO2 values on the pH/KH/CO2 chart. Again, we would have to make the assumption that the rise in pH is due 100% to the dissipation...

    It's exactly as Darrel mentions. LCP is a very low energy level and more PAR does not mean "better" growth. It simply causes "faster" growth.

    Purple Non-Sulfur Bacteria?

    I suppose there are those that will argue but the general consensus on this board at least is that BBA and red algae in general are CO2 related algae.

    Plant ID ?

    Well, I wouldn't choose to place the spraybar on a side wall. The reason is that the flow has a much longer path to take across the tank. We are depending on the water's energy to flow down the glass and to travel back toward the spraybar. Doing it the way you suggest means the moving water will...

    KH has nothing to do with distorted leaves. Distortion is either genetic or is due to poor CO2. Prune the leaf and observe the new leaf that grows. If the new leaf is distorted then it tells you that your flow or distribution of flow is faulty at that location. In your third photo of the...

    Hi, Yes, of course you can let the plant reach the top, but I would trim the top a couple of times to see the quality of the new growth. Often, when the plant reaches the surface it will improve because the leaves at the surface can breath CO2 from the atmosphere. If you allow the tank to...

    No, both staghorn and BBA are CO2 related algae. Your minimum pH reading (5.3?) should occur at or around lights on. Also, placing a filter outflow at an opposing angle as shown in your sketch, is not usually a good idea as it typically results in flow cancellation. It would be better if all...

    Switching to Low Tech Advice

    This is not possible - not even remotely possible. Light causes algae and CO2 grows plants, so you have a real problem of having too much light and insufficient CO2.

    Worsening algae after starting EI dosing

    Hello, A rule of thumb is that if you are dosing EI level of nutrients and the tank experiences nutrient related algae then one must immediately suspect that flow/distribution is faulty. It was difficult to see exactly how your distribution is configured, but it appears you have a...

    Oedogonium and diatoms?

    Hi, Yes it was my suspicion. If you do not have the ability to dim the lights and cannot raise them then as wookii mentions, you can use floating plants to reduce light penetration, or any device can be use to obfuscate the light, such as dark perspex or even cheesecloth placed between the...

    Oedogonium and diatoms?

    I agree with Oldguy. When you see algae growing over so much of the hardscape then it is a sure sign that there is too much light. If this is a CO2 injected tank then flow and distribution are also suspect but I cannot see the filter outlet orientation and it is unclear whether this is a CO2...

    What types of algae don’t spread from spores

    Actually, in a broad sense, yes, there is a difference, but that difference is NOT what The Matrix would have you believe. The difference lies in the origin and the location of PO4 within large organic structure. The PO4 ion itself is the same as inorganic PO4 but in organic compounds it is...

    Finally taking he plunge on monster tank - Help with kit list please!

    Where is this rule written? There is no need to oversize anything, just use a couple of adequately rated filters. Here is a myth-busting 150 gallon tank powered by two Eheim 2180 Thermofilters. You can just make them out on the lower edges of the photo. Note the cheesy Eheim spraybars, two each...

    Understanding CO2 / pH / KH

    This is incorrect. You absolutely cannot determine the CO2 content of either the tap water or of the tank water by simply by using the pH/KH/CO2 table. If you do this you will consistently overestimate your CO2. You need to ignore the table and ignore the LFS advice until you have a much better...

    What’s everyone’s thoughts on aquarium testing kits (Newbie)

    Hello, There are no test kits that are in any way "ideal" for a planted aquarium. The problem with test kits are not merely because they are inaccurate and inconsistent, but that test kits and testing for parameters that very few understand is part of a wider conspiracy by vendors to...

    PH profile, good then bad?

    It doesn't even matter if you have 15 DCs. The distribution of any of the dissolved gases, if it could be visualized, It would look like a vector field, with a different value and a different rate of change of value at every point in the field. So there is no point in using multiple DCs. Simply...

    Why doesn't return my DC to blue..?

    That's true. In a CO2 injected tank the unit does not add any more oxygen during the photoperiod because the solubility of oxygen is extremely low. It's the same reason we see oxygen bubbles when the plants are pearling. The oxygen production rate exceeds the solubility. At night (and early in...

    Black Spots on leaves

    Hi Chris, Yes, it's really difficult to understand all the stupidity surrounding this. Is it any wonder why there are and have been so many wars on Earth? I'm always wondering whether there is any limit to human stupidity - and the answer appears to be..."no". :hungover: Anyway it...

    Help...Low tech with EI dosing and the new IFC calculator

    Yes. Light energy dissipation follows the inverse square rule. Therefore at double the distance the PAR is at 1/4th the value. Roughly speaking, in air and in the absence of any other factor, if PAR is 220 micromoles at 20cm then it is approximately 220/4=55 micromoles at 40 cm, 220/9=24...
