What does it mean if my FOWLR is growing coralline algae on snail shells (occupied or empty) but not on the rocks or glass?
I have noticed spots of what appears to be dark red coralline algae growing on snail shells (mostly empty ones).
There also appears to be patches of purple and lavender coralline algae growing on the shells of larger live snails.
As far as I can see, the rocks and glass are completely devoid of coralline algae, though one rock that was re-situated seems to have coralline algae on the bottom where the sand previously covered it. I am not aware of any organisms in this tank that would consume coralline algae.
At this point, I do not have any pictures to share, but I will try to get some soon.
Water parameters seem to be pretty stable, though I do have high nitrates right now that I am working to correct with water changes after acquiring this tank about 4 weeks ago.
Salinity: 1.023-1.025 specific gravity
pH: 8.2-8.3
Ammonium: 0 ppm
Nitrites: 0 ppm
Nitrates: 200 ppm
Alkalinity and Calcium are both maxed out on the color-changing test strips.
