Yeah, that sorta looks like my tank after I stopped using a filter and the food pellets dissolved. That's gotta be the driftwood. I had just a few branches in mine and what a friggin' mess.
What Sena says does show heaters can cause a problem like this. She's a smart girl and I trust her opinion. I wonder how the heater causes things like this though.....
finnfinnfriend* Below is Sena's quote. I am hoping she see's this and chimes in.
"Try removing the heater... See if it stops. If it doesn't, good that is not the culprit. I am used to 1. heater snot. Icky, gooey, slimy stuff. OR 2. protein film. It could very well be the heater (or heater snot :) ) Is there any smell in there? Like, rubber, decay, rotten eggs, sweet, etc?" -Sena
