Bad PE!! Too low nutrient environment?

[SpSChief85]

OK so I feed once a day around a cube of brine or roughly a gram of pellet and or a 3x4 inch sheet of nori. I've noticed that my skimmer pulls less lately. I got a wild hair and built a DIY turf scrubber as an experiment about 5 months ago and my levels are undetectable as far as nitrate as phosphate, yet I never do water changes literally to siphon detritus off the bare bottom I'm running. My PE isn't good if at all on new additions but my sunset Monti, Ora green purple polyp bird nest and Ora birds of paradise have nice PE... my green slimer is iffy on the day. I've noticed on my acros that they have thinned out. I'm leaning towards the whole too low nutrient environment as the issue but am open to some other idea's and my levels are as follow alk 8 Calc 460 mag 1360 dose diy 2 part daily and kalkwasser in ato.

feed more, i improved pe with more food and very low no3 and po4. sps' don't feed on no3 and po4 directly.

If you are getting thinner looking corals, they are probably being starved out. Colors can start to fade as well as PE. Also check your temp, salinity, water source (change rodi filters) Sometimes it can be something that simple.

I would allow your nitrates and phos to raise some. My pearlberry was the most beautiful baby blue and as I lowered my levels the coral lost the blue and turn more white. As I allowed the nitrates and phos raise the blue has come back and I have seen better p/e. I also have started to feed a home made food with mysis, krill, brine, copepods, rotifers, nori and some chopped up larger krill. I have been only feeding this mix for a week or so now but I think I have seen an increase in the p/e in my cali tort.
My nitrates are running about 2ppm and phos at about .04 with hanna checker

Thinner sps corals is also due to not enough water movement.

Affected by light as well.
