sps go pale every 4 weeks

i have a 300g mixed reef ... mainly lps. my filteration is SWC skimmer, algae scrubber, gfo/carbon reactors. Every 4 weeks, my montis go pale and begin whitening. Zoas, softies and acans are fine. To correct the problem, I have to do a 20% water change and things are back to normal the next day. Keeps happening about 4 weeks in.

Fish stock Naso, Hippo, purple tang

Alk is 9.3
Calcium 460
Mag 1420
Nitrate 5
Phos .03

I initially thought it was my vodka dosing a while back, but I removed that from the equation and now I'm thinking the ATS is stripping a trace element thats required by SPS. Anyone else have a similar problem?

I had a similar problem with my 220. I was running my ats too much and system was too clean. How long are you running the ats? I only run mine now 10 hours per day

You're running an algae scrubber, carbon, and GFO? You're polishing your water to death.

I have the same problem with my Montipora except that it takes about 4 days for them to go white again. I can’t seem to figure out what’s going on. Water change is the only thing that gives them some color back. I’ve tried feeding more, dosing trace elements and adjusting my lights. Nothing seems to work. I’ve stopped messing with them because I don’t want to destroy everything else in my tank chasing a problems. I’ve just accepted it. Hopefully they’ll come back around.

Are you dosing to maintain alk/cal/mag?
And regularly measuring those?

if I was polishing water to death, why would a water change fix it?

my thought process is since water changes are fixing this, Im stripping trace elements. i just need to know which one so I can buy the testkit.

most likely the trace element you are depleting won't have a test kit available

Right.. because youre adding the stuff you're polishing out of your water. There aren't test kits for trace elements.

It's like having healthy kidneys and hooking yourself up to a dialysis machine. Why are you running a scrubber, GFO, and carbon?

i always had problems with nitrates bc chateo never worked for me. While gfo handled phosphate, I needed a better method at reducing nitrates. thats where the scrubber came in. and it worked.

I use carbon for polishing... makes water crystal clear
gfo is for phosphate control

i guess if nobody else has a solution, I can take the gfo/carbon offline and post back a month later?
