sand bed? My tank started to get that carpet looking algae growing. I've done water changes (4 times in a week to be exact). I've siphon my sandbed. But within 24hrs the damn algae grows back. I've taken Tyler's advice and added algone to my sump. Maybe I am impatient and would like to see my sand clean. So if any of you folks have a better method please let me know. Thank you in advance.
