Blacked out my tank.. sides and back painted black. I bought black gravel as it says on the bag. But the problem rn is air bubbles. It's all along the substrate it comes up in balls gravel then floats to the top. I can easily pop them or whatever and the gravel falls back down. But overtime more come up. I started my filter and all that did was make the air bubbles cone faster. Pictures down below. No fish have been placed in the tank yet.
Haven't had gravel in years... but when I did all I did was a quick rinse whenever I did a water change then I would proceed to replace the old gravel. Did the same thing with this black gravel made by topfin. What should be next step? Just leave it?
