is the green algae more desirable than the brown ones. my tank initially has got the brown one on the tank glass, now the green [light green] one starts to appear. and when i scrape it off, the o clown seems to like it very much and consume it as if it is very delicious

do you mean high KH? understand that when alkalinity is too high, calcium will be precipitated? any bro got such experience before?

pls pm me
