Half the fish were in, the rest just went in now. But I fed the tank even without fish, as I have a lot of hermits, shrimps, etc...

I've always had low readings though, but I did expect some PO4. I'll test again in a month and see what the full fish load does.

But without those big fish there was no fish poo. Anyways, I'm jealous so I will try to justify my high readings someway!

Last time I tested, it was really close to 0 with all my fish. Mostly I'd say the big water changes help a lot.

I have 0.5 ppm phosphates according to redsea test...all my SPS doing great and having great color. Should that not be possible with such high phosphates? I also doubt my test especially that I have been dosing nopox and now the algae don't even grow on my glass...wierd.
