honestly the best way to get rid of that ####ty algae is just to turn your lights off for a week and really realyl don't feed your fish alot... and put in some algae eaters... ottos mabey but the algae eaters will just chew through it and eat it all up... BUT the key is to underfeed and keep the lights off... I did that and it ELMINATED the algae outa my tank... its great
