NT Labs Sludge Gone

Didn't seem to do anything positive or negative.

seems to do job well

I bought this product as Interpet Sludge Buster wasn't available. Wish I hadn't wasted my money. I mainly keep mollies in my tanks I find that the filters accumulate a lot of sludge even though I don't overfeed. This product did absolutely nothing! Buy Interpet Sludge buster as it works wonders.
