Sickly euphyllia

[Shackleton]

I have two euphyllia, a hammer and a torch. The hammer looks awesome and the torch like death warmed over.

Why the disparity? What to do about it?

My parameters are:
Ammonia 0, Nitrite 0, Nitrate near zero, dKH 10.0, Ca 440, PO4 0.24, pH 7.9 (can’t get it higher in the winter), salinity 1.025.

Difference in par levels possibly. How much light does one get over the other?

 

[DarthSimon]

Phosphates at .24 are starting to get on the high side, and can effect Euphyllia. I would try and lower them down.

Also if those are deep water Tongan torches, first they looked like they are starting to get bleached. I would lower them down to the sand and get them in less par.

Are they Tongan or Aussie? I have tried a bunch of Tongan Torch colonies, and they all bleached out under my Radion's

I don’t know. The LFS didn’t mention it.

Here are their relative locations. The hammer gets more light and more flow.

What kind of lights and intensity?

Stock lights that came with the Fluval Evo 13.5. I don’t have a par meter.
