My tank has been cycled for a week now, running for over 2 months total.
Upgraded lights a couple weeks ago and started dosing with flourish excel yesterday.
Today I noticed the my filter his this greenish brown growth and some white fuzzy stuff on the suction cups on my heater.
Any idea what it could be? I tried to clean off the suction cups and now I have little white debris floating around the tank
Should I clean off the filter also or will the flourish excel eventually clear that up?
