Growth and color issue

[DopeCantWin]

As the title says, I'm having growth and color issues. I'm worried its because of nutrients. A lot of brown polyps, no extension on some corals. According to Salifert, my Nitrate is 2.5, and every time I've tested Phosphates, it's been negligible. But I do have quite a few large fish. 2 3-4" tangs and 6" Foxface in a 90. And quite a few other fish. I'm thinking about taking out the Foxface and one of the tangs. Does anybody else agree?

I think that would be a good idea, but more info would be helpful. What are the other fish? What filtration do you have? etc.?

Bump?

nitrate at 2.5 isnt bad. a lot of people run 2-5 and prefer it that way. whats your alk,ph, calcium, and mag like? stability is key. lighting is another good one too so more info would be great.

I decided to go ahead and get him out. Broke a bunch of corals in the process. Got him out, he was fine for a few hours. I go down to take him to the store, and found he had died. He looked okay earlier. ****ing sucks.

No, i dont think you should take out the fish, do you have a protein skimmer? your nitrates are soaring above lethal, you should get a skimmer if you dont have one yet!

2,5 nitrate is not even close to bad.

I've done fine with 25 nitrates...WWC old 300gal display was usually at 25 too

I run between 2.5-0 nitrates no issues. I have most of those fish (minus the fox face), What type of tang? I have the same skimmer as well. What's your lighting and water motion like? Have you checked for pests, how long have you had the corals in your system? What are you other parameters alk, etc and how do they move over the course of a week?

Yeah 2.5 no3 is no where no bad that is darn good in fact. Dont respond if you dont know what you are saying please, it spreads misinformation.
OP what lighting do you have and flow?? I would also look at stability.

 

[DopeCantWin]

Lighting is 2x AI SOL 1 50/50 Reefbrite 1 Actinic Reef brite

The time on AISOL is something along 10 hours 84% on for B and RB and 120M fade in.
5 hours 60% W with 120M fade in on each side. Stability hasn't been great, but I figured stability wouldn't really cause the color issues.

Stability is key and I mean KEY to keeping sps colorful and growing. Ca, alk, mag, SG, no3 and po4 all need to be very stable.
