How often do you feed your pleco? I was feeding mine an algae pellet every night, and it was gone by morning so I had no worries. Between my pleco and my barbs, it was being eaten (the barbs loved them). Recently I posted a thread looking for help because my pH and ammonia levels were all outta whack and it was killing off all my fish. I never found the cause but eventually got the water straightened out, though not before it killed everything but the pleco. A couple weeks later, the water turns deep green. I tried for three weeks to get rid of the algae bloom but it wouldn't go away. I could change the water every week, change the filter, use drops to clear the water, all to no avail. As a desperate measure, I quit feeding the pleco an algae pellet every night. The last pellet I fed was Sunday night. I vacuumed the gravel well and changed the filter Monday morning and have not dropped an algae pellet since. The water is now crystal clear. I've concluded the pellets were what was causing the algae bloom. So my question goes: How often do you feed your pleco? (Mine hasn't been fed in three days.) Do you feed it algae pellets or does it simply survive off of algae growing on the walls and decorations or food which has settled to the bottom of the tank?
