Good and Bad ??
Acros, Cactus, Blastos, Galaxy coral, and Acans all doing great. However Torch, Hammer and Duncan corals are all deteriorating. Temperature is consistently at 77°, phosphates are 0, nitrates are 20 SG 1.027 —— I dose with Redsea products and AquaVitro products. The tank has a fox face, clown fish, damsels, and electric blue and scarlet hermit crabs. in addition, a few brittle stars and sea urchins. What parameters would cause a few corals to slowly deteriorate while the others mentioned above are growing, expanding fully and have good color??

The low phosphate. My phosphate are zero and I noticed my torches and euphyllia have gotten thinner tentacles

A mixed reef is very challenging, you get your parameters right for SPS, and the LPS wither, and a little on the “dirty” side, SPS bleach. I have an SPS dominant tank, and very few LPS do well..
I feed reef roids, and oyster feast every other day, and my hammer and frog spawn , bubble coral do well... Sent from my iPhone using Tapatalk |

You likely don't have one and as such are doing more harm than good running it.. GFO most certainly be too efficient when not needed..

Thanks for the good input, I have been in the hobby for years but watching some corals just expand in full color and grow, while a few just deteriorate is baffling. Not only not expanding but tissue is receding. I also feed Oyster Feast and Reef Roids. Over the years I’ve had plenty of corals to decline but not three and four at a time while everything else is in full color and growing —- usually it is apparent, some parameters is way off like temperature, specific gravity, calcium, alkalinity, lighting, water flow, etc. this time it is not apparent.

Measuring PO4 with Red Sea Phosphate test kit and sometimes with API

Your po4 could be .05, which is fine. Or it could be below .005 which I'd bad. The Red Sea PRO po4 kit gives a pretty accurate >>> Low Range <<< reading. You need that kit or the suitable Hanna checker. po4 value is important. It can be the limiting nutrient for coral growth. po4 should never be zero, & especially with high no3 like you have. The cause of tissue necrosis. Get an accurate low range po4 test kit & aim for a value of 0.04 to 0.1 ppm. Lower no3.
