You've told me this before but I'm already dosing 2ppm each week and CO2 levels are 30ppm. I guess I can try dosing 2ppm twice a week, see if that helps.plantbrain said:Giancarlo, I have your solution.
PO4 and more of it along with good CO2.
See Carlos's Green spot issue with high light+ Anubias.
I hated that algae but seldom had it in my tanks.
When I did not dose PO4 later, it appeared.
Sounds like you need a big cleanup.... time to get all those things out of the tank and into a bucket of H2O2. It works quite well on items that are hard to scrape, specially items that can be removed from the tank.vancat said:I vote BBA. When my SAE went into retirement, it invaded even the gravel. Now I have young SAEs working on it for me.
Shee-ut, I've got to go in there & pick out individual pieces of bearded substrate (gravel + fluorite). And it's almost impossible to scrape it off round things, like filter tubes, heaters & CO2 tubing.
With God as my witness, I'll never go without SAEs again.
