Can you help me out a bit with the theory?
Doing a 15gallon tank and was thinking ofc about doing a walstad tank, but i find this Dennerle Deponit Mix Black 10in1 4.8kg, it says that just this canister is enough for my tank. It's covered by sand as regular soul would be.
How do these new age pellets work? Do they provide the same bio engine as soil? It's seems simpler? I already found a place to buy good bio soil. But i'm not sure how the biology works best!
Thank you!
