To give more details I'm having issues with my 5 year old 80 gallon some corals just not bright anymore, slow growth not looking healthy like they should and some smaller zoa colonies pest free partially close. Large zoos fully open and look fine. I do run carbon monthly for allelopathy. I run a algae scrubber with a single sided 12 x 13" screen. The scrubber fills with 1-2 fist full size algae weekly but some spots closes to lamp turns yellowish. Figure its because the flow rate isn't consistent so its weak. Would this explains why I still have some algae growth in display tank if so why do the PO4/NO3 tests show zero? Don't know if corals having issues because too little P04/NO3 or too much. I have a red sea phosphates test kit and it shows zero no color. I took water sample to LFS and they confirmed no PO4 or NO3 both zero. What test kits show actual true readings? I have 5 large fish and feed twice a day 1.5 frozen cubes so I'm introducing a decent amount of food also because PO4/NO3 show zero only change 5 gallons a month. Could my 10k maxspect razor be a problem not enough blue leds?
