Hey everyone, Ive been having to clean the sand about every 2 weeks (siphon it out, rinse it) I was wondering why it gets dirty so quick, about 2 weeks after I clean it, it turns a sickly brown color. I read online that it could be brown algae, so I shut off the light about 2 hours early each night, but I notice no big difference. I was also wondering if it is the bio load that may be causing it, but most of the fish I have don't have a very big bio-load. Is there any way to stop the algae? and if it's the bio-load, what do you recommend I do? Thank you everyone for your time!
