I recently setup my 75g tank with Timberline potting soil (1") from Lowe's and capped it with pea gravel that came with the tank but looks like to come from Lowe's as well. I have 4 pieces of "driftwood" that I got from a cichlid breeder when i bought the tank. Tank was setup about 2 weeks ago and I immediately added a bunch of hornwort and a few other plants. About 2 days ago I noticed what looks like to be mold in a few spots under the gravel.
My stock so far consists of
5 german rams (added 1 day after tank was setup)
9 otocinclus (added less than a week ago)
21 glowlight tetra (added less than a week ago)
5 synodontis zebra catfish (added 2 days ago)
- "the driftwood", it seems kind of soft and very dark compared to driftwood ive seem on the internet (I've never owned driftwood before), so maybe its decaying?
- the gravel, maybe i didnt clean the gravel enough. When i first got the tank, the gravel was still in there with the driftwood and a little of old smelly water
I need any help possible!
