Unhappy corals, becoming cryptic!

[joelat]

Hi all,

I'm looking for some advice really. I have been experiencing some issues with my corals for the past 2-3 weeks now. Initially I had found a faulty power head giving me a fair amount of stray voltage into the water (nasty zap!)

However since rectifying this I expected to see improvement with my corals.

I currently have a torch, purple Kenya, rhodactis mushroom.

I have had multiple spin tests done in the water and everything is within range for the usual range in my tank.

I have done 2 30% water changes over the past 7 days.

I have also added Cuprisorb and carbon in case of any metal contamination from the defective power head.

Next is to send for ICP but I feel as though I have already carried out and potential fox that would come off the back of that with water changes and cuprisorb?

any other ideas? I’m at a bit of a sticking point now!

The second coral may not like being placed in the sand and/or that low, but lighting (PAR) is something you should check to ensure your corals are getting enough light.

I had only moved that this morning more for observation purposes, it was the same when on the rock.

I am also trialling a higher setting on the light for today and tomorrow. But they were fine before on a much lower setting. I can’t figure it out.
