Thanks for the suggestions. Lights are on for 8 hours, pH is 7.2, KH is 4. Heater's a Fluval M300, steady at 78F. Filter's a canister, flow seems moderate. Gonna test the CO2 levels tomorrow.


Those numbers sound decent. If CO2 is stable, maybe look at trace elements. Are you dosing any ...

Could be a CO2 imbalance. What's your pH and KH? If those are off, it might explain the plant melt. Also, check for any recent changes like new decor or water source.
