So I’ve been noticing some small white circles appearing on the tank glass - none at the front or ends, just at the back, and now one in the sump. I though they might be some sort of mineral deposits but from the one in the sump now I’m not sure - is this a limpet/barnacle of some description?
They’re about 1/16” to 1/8” across, have maybe 8-10 of them in various locations, have not noticed them shifting locations.
Photo is looking through the glass. Apologies for poor quality - using phone and testing the limits of its auto focus and zoom…
