[muggle0981]

Purchased a red cyanaria about 2 months ago

Not sure if a light issue-run 3 radionxr15 pro on lps/soft setting at 53% intensity. Tank parameters

Calcium 480
Phosphate o-.1 it fluctuates
Nitrate 15-18

not sure if should move uo-don't have much space to put on a ledge

Pics extremely dark to determine anything. Please repost under white lighting. Assure Phos and nitrate not elevated and its receiving moderate light and flow without sand getting on it

This is what we see:

Never let the phosphates zero out or get too high . Try to keep all parameters stable . The rapid fluctuation could be enough to tick any coral off . Lighting and flow could also be a issue . Can you elaborate a little on time, intensity, and duration of lighting . And they don’t like direct flow

Its not in direct flow-the jebao grye is above it

lights go on for 8 hrs-ramps up 30 minutes and then ramp down for hr at end

run lights at 53% on the lps/soft coral setting for radion

I had a symphillia coral that seemed to not be happy and then moved 1/2 up in tank and seems happy-wondering if will be the same for this cyanaria
