Help please - corals losing color

[Vaughn17]

Ok thank you taint (lol) and diesel. I will bring up temp and salt. Sounds like I just need to wait longer before adding more coral. Not sure what else to do. Trying to stay patient.

Listen to Diesel...your nutrients (i.e. NO3 & PO4) are very low. Your corals are probably starving to death.

 

[Diesel]

A. Total water volume ( Please include sump, etc.) 40 gal - Innovative marine rear sump

B. What are your parameters? ( CA, ALK, PO4,Salinity, etc.) CA 470, ALK 9.2, P04=0, Salinity = 1.023, Mg=1300, Temp = 76, ph 8.1, No3=0, Ammo=0

C. Type of lighting. Please include age, watts, and bulb/ballast name. IA TwentySix HD 90W LED

D. Filtration method (Skimmer, GFO, DSB, etc.) Protein Skimmer only - run pretty much 24/7, but will turn off for a few hours here and there

E. What types of corals do you keep. (N.A) - softies (green torch, hammer), prism favia, jack-o-lantern leptoseris - all around a month in the tank - prism and jack - may they R.I.P.

F. How long has the tank been running? 3 months

G. What are you dosing? Dosing schedule? Was dosing Tropic Marin All-for-reef minerals, but stopped when reached appropriate hardness.

H. Which brand of salt are you using? Tropic Marin pro reef sea salt - not cheap!

I. What brand of test kits are you employing? API and Red Sea

J. What are you using for CA/ALK supplementation? TM as noted above, but stopped because that started to look good

K. What are you using for flow? (Pump names, how many, placement, etc.) IM tank has two rotating nozzles on inlets plus one additional power head i bought separately to increase flow.

I'm doing weekly 10% water changes now routinely. Trying to stay patient. Thanks in advance

Thanks my friend, good info.
As I said before that your nutrients (No3 Po4) are too low.
If you have filter sock try some flake food in there to boost your nutrients.
Not too much you a pinch or two between your fingers, that will slowly bring your nutrients up.
If you use the Tropic salt your ALK should be already at 8 and that is perfect, no need to bring it up more by dosing that stuff.
If it drops just do a 25% water change and it will bring it back in balance.
There is really nothing in your tank that consume the ALK and CAL.
Here is your game plan for next two weeks, bring up nutrients, do twice a week a water change, run for a few days some activated carbon just in case you have some heavy metals in your water that can upset your corals.
After two weeks get a few cheap corals, like a single mushroom, small frag of regular zoa's and if you can find it a galaxea coral.
Keep these corals alive by doing nothing that keep the balance as your tank is, no nothing on dosing or extra feedings just flow, light and a once a week water change.
Also do you have fish in there?

Ok thanks. I have two clowns a blenny and a tang. I know, I know the tang will outgrow the tank

Oh man you shouldn't have said that............. lets start over :D

So you have 2 clowns and a blenny and you had a Tang that you had to find a larger tank for. ;)
Good stick with the clowns and blenny till corals are doing great.
