I do 20% water changes every two weeks. I suspect that I have been over feeding but it has not been an issue for my existing lps but since I added the SPS I have cut back on the grub.
Raising the temp is easy enough. I have been cooling the sump by running a fan across the surface because I thought the high temps were contributing to the film algae on the glass.
Perhaps I should make this weekends water change a big one?
