Anyone know how much ph affects plants? I have some crypts, anubius, pogostemen, scarlet temple and a Madagascar lace leaf. My ph is around 8.1 most of my plants are growing but don’t look that great. 2 of my 3 anubius are mostly dead but my lace leaf is about to flower. Wondering if it is a ph issue to much flow or something else. I have a fluval 3.0 plant light and a aqueon led for lights and I use easy green once a week. Ammonia, nitrite and nitrate are consistently 0. Kh and gh 6-7. Any suggestions on what I could do better for them?
