Cloudy Water Ideas

[ruslicus]

So my PH range during the day was 7.8 to 8.1. which I think is ok. My issue is even after change of GFO and checking the outlet from GFO rector I still get 0.04-0.08 PO3? any ideas how I get PO lowered? GFO doesn't look like working?

Denny from Concept got back to me with following results:

alk : 8.53 vs mine 8.7
phos : 0.03 vs mine 0.08
nitrates : 0 vs mine <0.25
amonia: 0
calcium : 375 vs mine 430

My biggest concern Caclium and PO3 are big difference. What is the most accurate Test kit for PO3 and Calcium? Still my SPS are upset so should be a problem somewhere. Ideas?

So water is crystal clear now, which is good. But big issue cannot drop PO3, at least based on Red Sea test kit. My numbers today:
1. Salinity 1.025
2. PO3 0.08
3. NO3 based on test kit it is negative can it be a problem for SPS coloration?
4. Ca 450
5. Alk 8.6
6. PH 7.9-8.2 during the day

My pocci still not puffy yet.

Good to hear about the water. That's progress. All other values look reasonable. Phosphates should continue to drop over the course of the week if you have just installed new GFO. Test again on the weekend to see where it's at. 0.08 is nothing to panic about though :-)

Pocci (and other corals) may take much longer to recover from whatever shocked them. Could be the cloudy water, could be the paramter swings. Who knows, but whatever it was, their recovery may be a long slow road no matter what course correction you do now.

Kien you my mentor will follow your guideline! Thank you!

So today I've got my Hanna PO3 checker and I am getting 0.03ppm which aligned to Denny's result. I used another Ca test Red Sea and I am getting 410ppm. Mine was showing 450ppm Should I start dosing a little bit Ca or keep testing couple of more days to confirm Ca is dropping? Alk dropped to 8.4, PH range 7.9-8.2.

And once again, all your numbers look just fine :-) P03 is reasonably low should continue to drop (although probably at a slower rate) from this point onward. Ca at 410 is great. What is your target? When I was dialing my Ca in I waited an entire water change cycle to see what the total drop was between water changes, and then calculated how much I needed to dose to compensate for the Ca drop in between water changes.
