I use Red Sea for everything, then a second nitrate test with Salifert. I don't have access to a phosphate test kit, I don't even think my LFS sells them.Yes provided they’re accurate. What test kits are you using?

there is a thing as too much flow especially when you have a mixed reef not to mention certain toxins
I have one powerhead in my tank currently, and lots of live rock to break up the flow. It's in a low flow area with just enough movement to keep it free from debris as Tidal Gardens recommended
