    Black Spots on leaves

    Hi Chris, Yeah, I was watching the race myself. Shame about Hamilton going off into the gravel. He also had a slow pit at a critical moment at tire change time. I thought he should have stayed out another lap. I thought his comeback from 9th was epic though. Looking at the videos...

    Co2 dead spots but fish gasping... How to improve circulation?

    Hello Thomas, That's a beautiful tank, well done so far. Yes it is true that when your plants suffer CO2 deficiency and yet animals suffer hypercapnia then it's a safe bet that flow/distribution needs investigating. I don't know what an inline skimmer does or how it works as I...

    C. Crispulata var Balansae (tropica in vitro) - not growing?

    My Comments are based on 30 years of growing crypts. Because just like in the movie, it seems you have been programmed to think a certain thought that has nothing to do with reality. Now, I have no idea what branch of horticulture your expertise is in but either your statement regarding "crypts...

    C. Crispulata var Balansae (tropica in vitro) - not growing?

    This is another myth created in The Matrix. Having an extensive root system has very little to do with preference for nutrient uptake location. One of the hallmarks of aquatic plants is that they adapt their leaf structure specifically to uptake nutrients from their leaves. There are other, very...

    Black Spots on leaves

    Hi Chris, Well the center would be the best place to mount the Koralia, but it looks like most of your plant mass is on the right hand side, so maybe first try to mount the Karalia on that side just under the mid-point of that bar and see how it goes. Cheers,

    Black Spots on leaves

    Hi Chris, There is no image taken from the side, but it seems the streams are quite weak as they are not reaching the front glass until they drop almost half the height of the tank. I would shorten the spraybar because there is a preassure drop along its length, so the longer the...

    Black patches on Java Ferns

    Yes, and these are correct. One cannot have a low CO2 sweet spot when the lighting is too high. High light forces a high CO2 demand. There ARE a whole lot of low CO2, unhappy java fern posts The answer is always the same increase effectiveness of CO2 and/or reduce the lighting load. Cheers,

    Another Staurogyne Repens thread....

    Hello Dave, Well, yes, that is the beauty of Excel and similar in that is is a biocide toxic to CO2 related algae and at the same time many plants are able to assimilate it and use it to produce either CO2 or CO2 metabolites. The mechanism is known only to a few, but there are...

    Another Staurogyne Repens thread....

    OK, well then this is NOT a non-CO2 tank. Excel=CO2 but is not as effective as gas injection. You can increase the Excel dosing and/or lower the CO2 demand by reducing the light intensity. In fact, reducing the light should always be the first consideration when faced with any kind of...

    Vaccum the soil to avoid algae ?

    Well, yes there is a war between algae and plants, but it is not a war of who can eat the most nutrients because algae do not care about the nutrient level. Algae are predatory and they can get all the nutrition they need by simply attacking and collecting the nutrients from dying and unhealthy...

    Ferns not growing enough

    They are essentially a low light plant but we normally place them under duress in high light applications, thereby raising the demand for CO2 to an unacceptable level. Another symptom of this stress is black/brown spots appearing on the leaf surface. Cheers,

    Ferns not growing enough

    Translucency is normal for plants suffering a CO2 shortfall. Ferns subjected to our typical Megatron lighting require so much CO2 that supplying such a high concentration would annihilate the fish, so we are forced to simply live with translucent tips... Cheers,

    Water Chillers

    Hello, These are symptoms of poor CO2. If this is a non-CO2 injected tank S. repens will struggle. If this is a CO2 injected tank then you'll need to review your CO2 technique. Daily Excel dosing and frequent large water changes will help to rectify CO2 shortfalls. Cheers,

    Hello Simon, Glad you find the information useful. There is not much you can do to stop the fungal growth. It's just something we have to put up with. After a while underwater the growth will not return. Just continue to wipe clean as it appears until it stops. No need to buy...

    Creating CO2 profile - baseline PH

    Hello, Yes, all of that is correct. If the natural pH of the tank is 8.2 then your target pH is 7.2. At the end of the day however, it doesn't really matter if you are a few tenths off or not. Some probes (or reagent kits) cannot even measure that closely and 30 ppm is a mythical...

    New Fert Time and Confused... (Sulphur Levels?)

    OK, fair enough, and as evidenced by the tap water content, sulfur toxicity is also unheard of. No, this is down to the low CO2 levels typical in a non injected tank. The plants with holes either are less efficient CO2 gatherers, or are rapid CO2 users, or they are in an area with chronically...

    New Fert Time and Confused... (Sulphur Levels?)

    Well, the only reason you would get into trouble is if you continually obsess over these numbers and start doing crazy things in an effort to micromanage those numbers. If this is a non-CO2 tank then things happen very slowly (unless there is too much light). That tank looks pretty good to me...

    PH profile

    Hello, As noted above fish really do not care about pH, which is really just a calculation of the ratio of the concentration of acid ions (H+) to the concentration of the alkaline ion (-OH). Since this is a ratio, by itself the number itself does not tell us much and does not mean much...

    PH profile

    The goal is a 1 pH unit depression by lights on and If your starting pH is 7.1 then your target pH should be 6.1 and that 6.1 should happen at lights ON. The trick is to have an injection rate high enough, and to start the injection early enough to achieve 6.1 by lights on and to not have the pH...

    New tank trouble

    Hi Andy, Perhaps I phrased it inadequately. I did not mean that CO2 is bad for plants. There is no such thing as too much CO2. What I said was that NOT ENOUGH CO2 is bad for plants. Using a yeast based system is a very bad way to apply CO2 because it does not produce a sufficient amount of...

    Hi paranoid, This rationale seems reasonable, doesn't it? Unfortunately the CO2 mechanism doesn't always operate that way. When you add CO2 to the tank it affects the way plants use CO2. This is due to the CO2 gathering protein called Rubisco. In a non-injected tank the...

    Hi Paul, Single point calibration, really? OK, fair enough. Probably Darrel has a few posts regarding probe calibration. The probe's electrode outputs a voltage for each pH value and there is a theoretical straight line representing the voltage along which, ideally the probe outputs...

    First Planted Tank - Help with Set up plans

    Hi marzayyad, I'm relieved to hear that the distribution appears to be reaching a good proportion of the leaves and that the pH drop is in the right amount. I know that it's tempting to move forward with the lighting but really, until new leaves grow in and are producing, I...

    Errr...actually Paul, probes really do need a lot of babysitting and really ought to be calibrated prior to use. You can buy bulk calibration fluid on Amazon. A two point calibration is suggested (4.0 and 7.0). Cheers,

    First tank - some questions

    OK, thanks for that. I can see the DC looks more reasonable now. Nice video! The tall plants do disrupt flow a little bit and yes, I can see in the video that the plants in back are being blocked. You can try moving the DC to the very back of the tank just to see if you can get that nice color...

    First Planted Tank - Help with Set up plans

    Hi marzayyad, OK, it looks like you're close and lights ON coincides with the lowest pH more or less. Yes that's true as far as the injection technique goes. The important thing is that you grasp the idea of what you are trying to accomplish. You can always play with the...

    Yeah, I have to admit, I'm a Hanna fanboy myself, but I recognize they are expensive. My personal favorite is the combination pH/TDS/Temp HI98129 which currently retails for (gulp) only 144 Euros...The do make pH only probes for considerably less, but never mind, Milwaukee is good too. Just make...
