Review on 12 Count Greenpro Root Tabs Fertilizer Tablets: Ideal For Aquariums, Ponds & Water Gardens! by Steve Modesto

Revainrating 3 out of 5

Turns black under sand

I use this with Co2 booster and most of my plants are doing great. When I clean my sand, I find globs of black stuff underneath and I'm quit sure it's the root tabs that haven't completely dissolved yet. Don't know for sure but never had it before using them.

Pros
  • Safe for fish and other aquatic life
Cons
  • Can damage aquarium filters or water pumps
