My tank started clouding yellow a few weeks ago. No fish have died. They all look healthy. Parameters all check out. I've been doing steady water changes. Upped the carbon in my filter. None of it seems to be helping. Any ideas?
I'm not so sure it's DOC because you said no driftwood, plants, and don't even over feed. Just gravel, granite, and fish. I get the impression this tank has also been established for awhile.The caves are just the run of the mill formed granite ones you'd find at any lfs. There's just a little bit of algae growth on them, but that's normal. I've seen algal blooms and it's not it. The glass is algae free. Everything online points to DOC's, but I'm pretty anal about keeping a clean tank. All fish are accounted for so it rules a rotting one out. I'll be home in a bit and test the water again... Troubleshooting all I can and can't put a finger on it. This is driving me mad!
