Its supersoil potting soil. The bag says 0.09% phosphate and it also contains peat.
I'm also trying to cycle and even if I change my water I get high readings of nitrItes and nitrAtes, the ammonia gets used up but The nitrites spike and then stay high they never get turned into nitrates. Can you help me
I took seed from the filter and gravel of my 100g and I bought some from my LFS
