Hello everyone, I have been having some BBA on my slow growing plants such as Anubias, Microswords and even some of my Vals, and I have tried everything without success. I know that BBA can be mostly caused by Co2 not being right (fluctuations, not enough, etc.) but unless I am missing something, my Co2 should be ok, therefore I don't know what else do to fix the problem.
Here is my current setup and details:
- 75gl tank with wet/dry filter, 2000 l/h main pump
- Co2 pressurized injection via needle wheel pump and reactor (AM 1000), 1.3 minimum PH drop (70ml Co2 per minute)
- light: 7 hours a day (from 2pm to 9pm) with 120w running for the whole 7 hours photoperiod, and additional 40w tube running for just 4 hours from 4pm to 8pm
- EI fertilization with water change every 2 weeks.
- tank is heavily planted (see picture below) and plants thrive well (despite something must be wrong otherwise I wouldn't have BBA around!)
Here is what I have tried and didn't change a thing:
- increased circulation with a different pump running at 3000 l/h, but I saw no benefit... Instead my Java moss suffered a bit because of too high current (tried for 3 months in a row)
- increased Co2 amount a big deal to have almost 1.8 PH drop (fish were ok because having a wet/dry filter O2 is high)
Here is a pic of my tank:
And here is my current Co2 curve recorded with my Apex controller, co2 starts 4 hours before photoperiod and shuts down one hour before end:
Please, let me know if you see anything wrong in what I am doing that can cause BBA because I am pretty desperate.
Thanks in advance to anyone!
