What is your phosphate level?

.16 and it won't go lower

Are your SPS fine?

I'm using Zeovit for Nitrates and phosphate reduction. I feed a lot and it keeps the phosphates levels at 0.02-0.05. I prefer this system to GFO. I only have soft and LPS though.

too high need to lower my phos now, thinking for reducing my bio load

I have only 1 acro, it's brown but was that color when it got it 3 weeks ago. Trying to lower it. I have used phosguard and Gfo with no success so far.

What about this?

My phosphates are near undetectable, .025, I have had the best luck with sps when my nitrates ate 1-4. You can only test for inorganic nutrients, so even if you're test kit says zero, there may be enough phosphates for them. I run gfo sporadically, but heavy skimming, food at least 3 times a day and supplemental nitrates via spectracide stump remover.

I'm at 0.23 ppm on my hanna and my sps frags are thriving and my po4 was even higher but I have a 40 gal refugium ut I think if u feed ur corals enough good lighting and flow you can grow some killer sps with higher then recommended levels. And like someone else said once you've had your tank for multiples of years 5+ it things balance out how they should.

staying steady at .1 while feeding a ton, everything is coloring up nicely.

Without my gfo reactor it goes to .13 with just a third cup gfo in a phosban 150 it's at a perfect 0.02 Hanna checked 3x. 90g with 40b sump. Yet I can't seem to keep sps other than montis. :-(
