SPS corals dying

[hoboapocalypse]

Hi. I've been having issues with my 20 gallon tank. I have a small quarantine of 5 gallons with sps and lips ready to acclimate into the 20 gallon. In the quarantine, all corals have full polyp extension and encrusting the frag. I place a couple small frags of spas and lps into the 20gallon and within a day, The Sps began losing color and look like they are dying. The tips are bleaching white. The lps have polyp extension but looks stunted, like opened halfway or so and not full like in my quarantine or what you would imagine as ideal. I will place my perimeters below, please help!!!

 

Ecotech radionics pro gen 3 running at 30% and on 10 hours

Ammonia 0

Nitrite 0

Nitrate 2-5

Calcium 460

Mg 1370

Alkanlity 9

PO4 0.08

Ph 8.0

 

I use Red Sea test kits for all and I tested perimeters across 4 days. So these numbers are somewhat stable.

 

Only difference my two tanks is that quarantine is completely bare while the 20gal has dry rock that I cycled and live sand from Carib sea.

 

I am completely at a lost. Thank you for any help

Does the QT have the same lighting as your DT? Are the water parameters the same in both tanks?

^^ same ?. Sounds like you need to aclimate your corals to your lighting. Reduce lighting to maybe 6-8 hours and place your corals down on the sand and slowly move them to desired height over time. Frag rack works great for being able to move them up and down.

How long has the tanks been running? My tank had to mature for aprox 6 months before I was able to see color and noticable growth in my sps. Also the key is stability of parameters and water quality. If your ph and alk/ca are swinging around, not good. Same goes for temp and salinity. Do you mix your own water or get it from lfs? What kind of water do you use? Ro/di, tap, distilled, ro? How did you aclimate your corals into display?
