Hi, I have a Rena Filstar XP3 for a little over a month now, 40 gallon breeder filled about 2/3rds up, Mikey is a little over 3". I did my first filter maintenance last week before I left for New Orleans. I thoroughly rinsed the black filter pads and the chamber and I left my BioStars alone as I understand that's where the bacteria grow. Anyways, I left for a week, my husband is really good not to overfeed or anything, and I come back and there is brown stuff growing around my water heater (on mostly the tank walls, but some on the heater) and on my suction cups. I don't want to have to clean the tank again because Mikey doesn't like tank cleanings and I might have to get a lot of water out and dispose of it ...
Was I supposed to wash things differently? I assume now I need to wash the brown stuff off of the tank ... Any advise?
