    Twinstar 600e how bright?

    Hi everyone, long time no see. I'm setting up my ADA 60f again for my dwarf puffers, this time it will be a blackwater with some easy plants and no CO2. I was wondering how dim I should have my Twinstar 600e, I'm looking to grow Vallisneria nana, Cryptocoryne wendtii and Helanthium tenellum...

    Hi everyone, it's been a while It's a very nice surprise to see my scape featured on the UKAPS facebook, thank you @LondonDragon ! Unfortunately during lockdown I ended up shutting down the tank as it was becoming too much to deal with. A disappointing end but I would say that it was...

    Drop checker “sludge”

    I've found it's quite common, once you clean it out and then put the drop checker back in the tank it doesn't tend to show up again. Seems to often only show up on new pieces of equipment.

    ADA 60f rock layout

    I have added some Microdevario Kubotai however I have had a couple of jumpers so I will likely rehome them. Any ideas for more suitable fish? The flow in the tank is quite high for CO2 distribution.

    PH has dropped, KH is 0

    Tropical soil is designed to remove KH, as are all active soils. This is useful for crystal shrimp keepers. You should start using salty shrimp GH+ with an active substrate as there is no point in adding unnecessary KH because it will just be removed. Oscar

    Active substrate and KH

    Active substrates usually buffer the pH to around 6. They are usually aimed at crystal shrimp tanks which require soft water.
  7. oscarlloydjohn

    Active substrate and KH

    Yes, you should probably switch to the Salty Shrimp GH+ All the buffering substrate wants to do is remove KH, so there is no point in adding it. This way you will have more stable parameters. I use active soil without adding any KH and it works really well.

    Recharging purigen question

    Does Ferrous Gluconate Cause A Water Surface Film?

    I'm not sure about Ferrous Gluconate causing the surface scum, however from what I have read I understand it involves biochemical oxygen demand.

    Recharging purigen question

    Just tried to recharge my bag of purigen for the first time, left it in half bleach half water for 36 hours. Should the purigen become white again? I haven't seen much of a colour change since I put it in there even though I have been stirring it occasionally. Cheers Oscar

    Root tabs fert?

    I tend not to use the capsule style ones because I always find the fertiliser pellets or the capsule eventually gets above the substrate.

    Another EI question

    Usually if I leave my tank more than a week then I just stop dosing after the week. Maybe if I'm leaving it for two weeks I might dose half the amount in the second week. It's pretty flexible so just do the water change whenever you can.

    UK equivalent of WELD ON 4

    I think tensol 12 would work fine for that. Since it is low viscosity, it would be pulled into the crack through capillary action. Oscar :)

    Par Level for Red H’ra

    I'd say you can only get it to a strong pink under the best lighting, most people who have the really red H'ra are doing nitrate limiting. Have a look at this article: https://www.advancedplantedtank.com/plant-guide-rotala_rotundifolia.html Oscar :)

    Maintaining a Sloped Substrate?

    I use small pieces of correx (corrugated plastic board) to act as baffles in the substrate. TGM used to sell this as 'substrate supports' but correx works the same. I also use lava stones beneath the substrate to give some height. Oscar :)

    Frustrated with Tropica Aquasoil Buffering Capacity

    I don't even add any KH to my remineralised RO, because the soil (ADA) removes it all anyway. Supposedly the soil controls the pH.

    Drop checker lying

    I find they are usually quite hard to read. Even if it is yellow, there's probably no need to reduce CO2 unless the fish are stressed. Oscar :)

    Wabi kusa lighting

    Can anyone suggest an appropriate light bulb for a small/medium Wabi Kusa? It's about 20cm in diameter. I was thinking more like a generic light bulb rather than an aquarium/wabi kusa specific one. Could something like a 13w fluorescent work? Cheers

    EI dosing please help

    Cost difference is massive but for a smaller tank isn't too bad. Profito contains more micronutrients than TNC or APF and it uses multiple chelators so works in all types of water. Oscar :)

    EI dosing please help

    I would recommend a commercial micro such as Flourish or Profito in place of the aquariumplantfoodUK trace. Have a look at https://rotalabutterfly.com/nutrient-calculator.php for an easy way to calculate dosages. Any other questions feel free to ask Oscar :)

    Filter suggestions for 180l

    I'd suggest a JBL e1502 or an Oase Biomaster 350. With the Oase you can add a built in heater to get that out of the tank. You could go with smaller filters if you are doing low tech but for high tech you want higher turnover. Oscar :)

    ADA 60f rock layout

    I'll be doing a 50% water change about every 3 or 4 days with half RO and half tap until it's cycled. This gives me GH 7 and KH 6, enough KH to keep the pH up a bit for the bacteria.

    What is better?

    There are benefits to both options, a reactor is much more efficient and can dissolve all/most of the CO2 into the water. This means you go through it much slower. This isn't necessarily the best option for plants, because there is some evidence to suggest that physical CO2 bubbles touching the...

    Favourite trace fert

    I believe APF UK's trace mix is Solufeed B. I've used it but prefer something chelated with DTPA. It would work well with softer water but the iron becomes unavailable with my high pH. I've switched to using Easy Life's Profito because it uses multiple chelating agents. Oscar :)

    Sooo, I have a spare spot in my living room...

    I'd say a Wabi Kusa would work well in that space, a tank there will be a nightmare to maintain and you won't be able to do a syphon with it because of the tank level :) Maybe a very large, flat Wabi Kusa filling most of the space? Much lower maintenance too Oscar

    Where does all the CO2 come from?

    I have used the JBL proscan, and I think it is quite unreliable. Because the KH measurement on the strip is inaccurate, the calculation for CO2 is also inaccurate. Also any acidifying factors from other sources will show up as a false CO2 reading. I think the 0 nitrates is also most likely...

    Favourite trace fert

    Currently I'm adding 0.75tsp DTPA and 0.5tsp trace mix (APFuk trace) to 250ml RO water. I also add 10ml vinegar to keep the pH down. This is dosed at 4ml per 25L tank water. I'd say a dose of 1ppm iron DTPA on top of the TNC would be fine. You could use rotalabutterfly to calculate it. Oscar

    Hey Steve I think the only all in one trace with DTPA is Easy Life Profito (as far as I know). I'm yet to find a trace powder with DTPA either. What I've been doing is adding DTPA iron into my trace mix. I bought it off eBay as a 50g bag. Oscar

    Hi There

    Welcome to UKAPS :)
  92. oscarlloydjohn

    Does anyone use the JBL Direct CO2 test kit?

    I should have been clearer. When I say "fully saturated", I mean the peak saturation of CO2 you get from your diffusion setup (varies from tank to tank), NOT the maximum amount of CO2 your water can hold. Depending on CO2 timers ect, some will reach this at the start of the photoperiod, others...
  93. oscarlloydjohn

    Does anyone use the JBL Direct CO2 test kit?

    Measuring pH drop is basically the pH change between degassed and fully saturated. (nothing to do with the JBL test kit) This way, we don't have to estimate using KH values, which gives inaccurate results because of other acids. Instead, we just measure the tank's pH before the CO2 turns on...
  94. oscarlloydjohn

    Does anyone use the JBL Direct CO2 test kit?

    Yeah, I used it once and it's been sat in my cabinet ever since. It is very difficult to read, and I find measuring pH drop manually gives much more accurate results. I don't think that it takes into account other acidifying compounds such as tannins so it gives an inaccurate reading.
  95. oscarlloydjohn

    Critique my aquascape All critique is welcome

    I think you could do with some more rocks, especially around the base of the wood. Try to find ones with interesting texture and make sure all the rocks in the aquarium are similar. A deeper substrate at the back would give a sense of depth.
  96. oscarlloydjohn
