SPS newly question

[Treebeard]

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?

If you can, I'd do a 50% change. That will impact the NO3. The temp will contribute to the film algae a bit, but it's there for mostly the same reasons as the brown is in the corals.
That should clear up a bit once the other issues are settled.

I feed quite heavily (I guess that's subjective ) and don't have issues, so more of a nutrient management process. A great skimmer helps. Maybe smaller more frequent feeding? Or, if you're really dumping it in, back it off a bit.

[Treebeard]

I definitely don't dump in the food, actually the reverse. I contribute the high nitrates from the eels appetite for frozen shrimp. Having some buyers regret over that purchase, especially after he took a huge chunk out of a coris wrasse and my neon goby dissappeared. Ever since I make sure he is well fed, every three days.

What kind of skimmer do you run?

[Treebeard]

Vertex In180

Should be good enough. Run through the stuff here, see how that works, and update us.

how are you testing phos to get an absolute zero??

[Treebeard]

Salifert. I will retest tomorrow.
