my last guess is anaerobic converting any of the sulfates (potassium sulfate, gh booster etc) i dose in my tank into sulfide, sulfide stunt the plants and kill them.

the gravel vacuum is working fine and i was able to collect lot of dirt. am going to clean it more tomorrow. hopefully this will get rid of the anaerobic.
