White Spots on walls of Sump
Hello all. I have a 220 fish only salt water tank.
I have a euro fil 240 sump with a asm g3 skimmer
I noticed today that there are white spots approximatly .5 inch round inside the sump only? what is it? do i need to clean? PH 8.3 nitrate is approximately 20ppm 0 nitrate and 0 amonia...
Are they somewhat spiral-ly? And are they located where the area is somewhat darker?
And do they resemble this?
If so, they are Spirorbis. They are a filter feeder, and a sign your tank is doing well.
no spiral to them i will try to get pictures. White substance circular, small mound, some have a small crater inside. additional info tank is 9 months old, i keep minimal light in the sump area otherwise algae grows too much on my lines. ( any advise would be appreciated).
i keep the salt mix at 1.020. temp 78.
