In my order from Aquariumplants.com I got a free sample of AquaFertz Total substrate pellet. I'm complaining about it (in fact my whole experience with them was very pleasant). I just switched the substrate in the tank, so it has little to no nutrients for the plants. I would like to use these, but I want to hear about personal experiences with this first. This tank has had some problems with algae before, and I'm hesitant to add almost anything to it.
The bottle I got is the small one with TOTAL on it.
Thought I should also add that I already dose weekly with flourish comprehensive.
