How much and what fertilizers to use?
OK so I have the following plants in the 32g:
2 different strands of hygrophilia polysperma;
1 hygrophilia difformis
1 Cryptocoryne undulata
I add Nutrafin Plant-Gro to the tank once a week (0.15% nitrogen, boron 0.0005%, copper 0.0005%, iron 0.26%, manganese 0.05%, molybdenum 0.0007%, zinc 0.003%).
I have regular gravel substrate, nothing added, no other layers, no under gravel filter.
Is this fertilizer adequate for my plants? Is it too much? Not enough? Any advice here is appreciated!
