So I was looking at my 5 gallon tank with Kinu the CT and noticed this weird white fuzzy stuff stuck to the suction cups of my heater. Does anyone know what it could be? How did I get it? And how do I get rid of it (preferably without throwing out my driftwood and plants)? The suction cups are the only place I see it, and I'm not sure how long it's been there (the heater is hidden behind bunch of wisteria and I don't often look at it even while doing water changes).
This tank is pretty heavily planted with wisteria, anubias, frogbit, java moss, a marimo ball, and aponogeton. It is filtered and has some bamboo in the filter. Until recently it had been getting a 50% water change every 3 days, but for about 2 weeks now I've been doing a 60% change once a week (last water change was Sunday). Do I need to go back to twice a week?
For now I'm just going to remove the suction cups, rinse them off, and let them sit out for a day. Also, so far there seems to be nothing wrong with Kinu, but will it harm him? Thursday, I'll be heading out of town for 4 days so I hope he won't be needing any special care while he's in my step mom's hands.
