I do 2 water changes a week and after every water change a day later this green algae forms on my rocks. How do you get rid of this stuff? It looks trashy. Thanks for any help.

Last pleco bit the dust...actually my piranha did most of the biting, but I think that I will give it another shot.
With regards to a big snail would a raph cat be able to take down a big snail or do they just eat the small baby snails? If my raph couldnt take down a big snail then I could get one of them and the raph could take care of the baby snails. Make sense?

Blue green algae is actually a nitrogen fixing bacteria and is a common indicator that you don't have enough nitrogen in your tank as far as planted tanks go. If you're doing live plants you actually don't want 0 nitrates, because your plants need something to feed off of.

At any rate, the most effective way of killing blue green algae is with a 200mg per 10 gallon treatment of erythromycin phosphate.
