[Wet Elbows]

I'm a planted tank newbie myself but if you're looking for help, I suggest you provide all the info you can about your setup.

Water parameters
Substrate
Filter
Lighting and schedule
Fertilizers and schedule
Co2?
What kind of plants
What kind of fish and how many
Maintenance schedule

This info will help those with the experience to help you figure out what's wrong. Good luck!
