Is there a risk in me doing a water change after ~1 year of not doing any? My water box 15 hasn’t seen a water change in a while now, after a house move I got lazy. All the corals are doing great, and I’m seeing more growth after cutting water changes out than I ever saw whilst doing them regularly. However, the tank isn’t too pretty to look at. Cyanobacteria has come back in force, I’ve been having to stir the sand and blow the rocks everyday for a couple months now. The water surface is now looking scummy and water bubbles are building up on the side of the glass.
All of these issues do seem to be purely aesthetic, and as I say, the corals don’t seem to mind at all. I’d like to start doing a water change every 2 months or so, to hopefully fix the look of my tank. What risks should I be prepared for and what % change would you recommend if I do go down this route? Thanks!
