Aquarium Advice Apprentice
I have a relatively new 20g high planted tank. I used CaribSea EcoComplete substrate. How do I know when the nutrients in the substrate are exhausted? Then what? Should dead leaves be left in the tank as fertilizer? Some of the leaves on my plants (mostly swords and anubia) look soggy, like the edge of lettuce a few days old. What's up with that? I dose a little API CO2 booster every few days. Is this a good/bad idea? Is a CO2 diffuser necessary? Lighting is pretty weak, 15 white LED's that came with the tank. Thanks for the advice guys!
