Hi,
90gal CO2 tank now 4+ months old. About a month ago I was just starting to congratulate myself (or more accurately, thank Tom for his advice that I followed [in some cases against my own judgment]) because I had seen NO ALGAE.
Then some GSA and hair algae started to crop up. I killed VERY large clumps of needle leaf java fern spraying with 100% excel.
I adjusted flow patterns.
I pointed CO2 output directly into plants.
I did H20 changes frequently.
I recycled CO2 by bringing "false gas valve" of AM1000 back to pump intake.
I turned up bubble rate so it is so fast I can no longer count (maybe 8-10+ bps).
I just reduced photoperiod.
I'm hoping you friendly folk will offer me some input. I assume inadequate CO2 is responsible for my GSA, and thread algae.
I'm interested in whether my current design is adequate. On the surface it seems it should be --more than adequate-- for a 90gal tank. But apparently it is not, or I am not tuned in to what to change, and this is my problem.
The attached diagram illustrates my CO2 design. One possibility is to get rid of the AM1000 with tiny 1/2inch I/O and replace with larger reactor (3/4"? I/O). If I do that, same pump OK? I'm kinda lost in what to change.
What options, for my set up, would seem to make sense for enhancing CO2?
thanks for any feedback,
