I've been trying to get more into sps lately, and have had some success, but they all seem to color down over time. I have a medium to heavily stocked mixed reef in a 180 gallon. Oversized skimmer, chaeto, and carbon reactor is pretty much the only filtration. I feed a full 6x6 sheet of nori daily and 2 cubes of brine and 2 cubes of mysis plus 3 scoops of reef chilli daily. I have stopped doing water changes for the last couple months trying to get my phosphates up. Cannot do it, so I'm looking to dose it. There is little to no algae growing in the tank except the chaeto is growing pretty quickly.
Parameters are
Temp -78.5-79
Salinity - 1.025
Alk - 10.5
Calcium - 460
Mag - 1380
Nitrate - 5ppm
Phosphate - undetectable
pH rock solid around 7.95-8.1
Tests are using salifert.
I've never had this problem before and historically have always fought to lower them lol. I also have a dosing pumps for the alk and calcium.
This is the most stable this tank has ever been, but a little upset that my sps keep browning.
Also lights are 3 maxspect razor 120s plus 4 bulbs of t5, 2 blue plus and two actinic with a 3 hour peak. Flow is done with two 6105 tunzes at max and a various 8 return pump.
I was wondering if it was lighting until I realized my phosphate is consistently low. I'm honestly trying to run a little higher nutrient system.
Lastly, all other corals are doing great, hammers, torches,Duncan's, leathers, monties, shrooms, zoa's gorgis, etc. Only ones showing issues are the sps.
Any input is appreciated!!!
