Is his Finger Leather ok????

[10silver6]

This finger leather has been doing great for awhile but it recently started to get this brown algae it looks like and a little slime coat on it also, Also on another topic I also have some Yellow Polyps and they have been tucked in for about a week not, no loss of color just wont come out, I have tried moving them around in the tank to change light/flow etc and suggestions on that also? Thanks guys :hat:

Algae growing on it is no good. Have you tested your parameters? What are you using for filtration?

How much flow do you have?

its a 100 gallon thats 63 long and im using 2 hydor 750 and 1 of the nano hydors, as far as filtration I have a 46 gallon sump/refugium and a 4 stage canister with UV and also magnum 350 with just carbon in it, I am using RO/DI but I recently just got it and started doing water changes so I was wondering if the swap from tap to the good water could be causing it? All the other corals such as the xenia and musroom and zoos seem fine

No skimmer?

As far as paramaters im not showing any phosphate and all other levels are good except my nitrate is around 30 ppm
