Got it, so sounds like it’s still pretty fresh. I am by no means an expert, but from researching my own problem, it is usually best to wait it out, remove manually, and ensure good parameters. If that doesn’t work, then chemi-clean can take it out. Do be warned that using chemi-clean can leave opportunities for Dino’s to move in though, so be careful of that.
Depending on a few different things, your tank may be just getting its bacteria and the normal algae. From my experience, it takes from 2- about 6 months or more to really begin to establish a tank. Don’t be too worried when a little algae pops up, it’s normal. Just ensure good parameters, keep cleaning, and keep an eye on it. If it starts to get out of hand and everything else is looking good, chemicals can help.
