Hi I’ve noticed over the last week my corals don’t look too happy I was thinking maybe it’s because I’ve taken all my fish out and put them in qt a while ago I have no experience with keeping coral I test for mag alk calcium and nitrates I got a salifert phosphate test kit today my levels are
Salinity 1025
Mag 1350
Alk 8.9
Cal 430
Nitrates for some reason have shot up to 25-50 it’s hard to tell the exact colour
Phos looks to me to be clear to 0.03 I’m thinking it’s really clear but it does have a tint of blue if you do look for it I’m stuck I don’t know what to do after reading on forums I can either add phos do water changes use pellets or dose liquids to remove the nitrates I’m worried that if I choose water changes it’ll remove more phosphate I have cheato it’s still green but not growing looks healthy to be honest I run the light in reverse to my main display light I also use ozone I have crystal clear water and no algae I clean my glass maybe every 3 weeks and that’s only because I choose to do it incase I get any vermatid snails on it I hate scratches it’s been running since November could anyone help me out please

My nitrates was at 5 before I removed the fish I use phytoplankton to feed sea cucumbers I also have an harlequin shrimp I feed but I only feed small amounts of stars to I remove any left over matter

Are you still feeding your coral?

 

[Utubereefer]

Got a picture?

 

[Lee belk]

Of phosphate I’ll do one now

 

[Lee belk]

It does look a little more blue on the pictures

 

[Lee belk]

Would doing water changes cause phosphates to deplete anymore then they are already

Its very hard to help when the description is "corals don't look too happy", it helps if we can see. Can you show some pictures of the corals please? Full tank pictures also help.
