Moss gets eaten, hornwort grows what I believe is bba and growth on it slows way down in this tank. Crypts are the only thing they don't eat...so I'm going to get more variants this te around now that I know what works.
The soil was not mineralized, it has been in the tank for over a year or so, so it is now. The soil is shifting up through the sand layer, probably from me planting new plants multiple times. That's what I think is causing the high nitrates.
