I have been having a problem with my lps corals loosing their colour after being introduced into my tank, corals were healthy when purchased they had amazing colour but since i added them to my tank they had lost their colour after a week since being introduced into my tank and i cant figure out why that is this is mainly with my frog spawn and torch coral the acans seems to be doing well no loss in colour. I had tried a number of solutions but no success so far. I had started dosing alkalinity as when i tested for alk after i noticed the colour change it was at 6.7 dkh i am currently keeping it stable at around 8.5 dkh it been around 4 weeks with no visible improvement. I have tried increasing lighting, increasing nutrients, decreasing flow, changing coral placement and constantly testing water parameter. Current parameters: salinity- 1.025
alkalinity- 8.5 dkh
calcium- 480ppm
magnesium- 1380
phosphate- 0 on salifert test kit
nitrate- 2.5
Ph- 8.15
Salinity and temps are stable.
tank is 20 gallons 4 months old using chemi pure nano packets to help with algea. using ai prime hd lighting 9 inches above water level I also spot feed my corals. i will include pictures of light setting and pictures of corals. The torch is a indo gold, when purchased it had dark stems with gold running through them now it pale with light pink stems, frog spawn should have golden tips now they some are pale white or bright green.
