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

I just started a new tank. This works like a charm for my root feeders. They are pretty easy to push deep into the substrate so they do not leach into the water column and as a result they deliver optimal nutrients to rooted plants. I have placed a few around in my planted tank, and so far everything seems to be just happy and improved color. No crazy water parameter changes or anything weird. Given me confidence to try harder plants and will definitely buy this product again.
