My fight with BBA continues which I am still learning about but there's still a couple of things that are niggling me if anyone can explain.
Firstly I have been learning about how co2 levels and poor distribution have an effect on BBA so have addressed those issues first. I now have stopped being a miser and with my CO2 and concentrate on having a yellow DC from lights on time to lights off and have added a 1600lph Koralia to improve circulation to all dead spots in the tank. My issue is that the BBA increases in the areas nearest to the outflow of the Koralia. Considering that the diffuser is directly under it then I would have assumed this would be the last place the BBA would want to be in the best circulated most co2 rich part?
I have read somewhere that fast moving oxygen rich water oxidises iron which makes it inaccessible to plants but certain algae thrive on it, not sure how true or relevant that is.
Secondly I also dose easy carbo the recommended dosage daily to affected areas, now there are people in here that dose only EC and don't bother with co2 with good results so that begs the question, if I don't actually need co2 but I keep it as target as I can is that better or worse than not adding it at all? Does poor flow poor co2 distribution cause BBA even when EC is added?
I have 70watts of T8 over 155ltrs contemplating lowering the light but as I'm moderately lit to start with not sure if I will benefit. Some of the brighter lit loving species don't fair well to start with. The likes of the hair grass spread towards the lights with plantlets rather than bush out at the base.
