Pale sps corals

[maxwell]

Hi Randy
I have some tenuis sps corals that are very pale in colour , the other sps corals in the tank have good colouration .I have had an icp test and everything looks good with a recommendation to supplement strontium and molybdenum which I have started to do .What else do you recommend I try .

Not to be rude but are the Tenuis new acquisitions?

Very pale can mean excessively low N and/or P. Have you measured nitrate or phosphate?

Hi Randy
Phos = 0.018 , Nitrate =0
Heres a link to the icp test https://www.triton-lab.de/en/showroom/aquarium/auswertung-b/icp-oes/48983/
corals
Pink - 2years ( its a pale pink )
green/yellow - 1 year ( still showing little or no colour)
WD - 6 months ( very pale green showing yellow/blue tip but pale)
Blue /red tips - 1 year ( can see some colour but very pale )

Firs thing I'd do is look to increase nitrate, either by dosing or feeding more. :)

ICP looks generally OK, but some trace elements may be on the low side, and a supplement might also help. :)

I have a circulating reactor with pellets that I can adjust the output or switch off . I have a good number of fish that I feed twice a day and another 4 that can be added which are in QT tank. Or should I just try adding KNo3 if so what quantity its a 1000L system. Which trace elements should be added.

I'd probably take the pellets offline for a while.

What you mostly want is things that they call (for reasons that are nonsensical in this context) the I group and Fe group, and the since none are really high, a mixed trace element cocktail might be a fine plan.

Many thanks ,I have reduced the pellet output by half for 24hrs and then switch them off and monitor .I will order some trace elements today.

Many thanks Bill
