Been trying to cycle my new tank for the last few weeks. There’s no fish at all, just sand, rocks, driftwood, and some plants. I noticed some small snails after a bit, which I suppose snuck in via the plants. But recently I’ve noticed an absolute ton of these tiny white worms on the glass and swimming in the water. And there’s also this black spotty stuff on the rocks and plants. In general, my tank looks pretty gross; I’m kinda shocked at how bad it seems to have gotten after just a few weeks of cycling. I’ve been doing water changes but it doesn’t seem to help for long. Is this gonna be dangerous for fish? What should I do?
