I have been going to Walmart the fill my 2, 5-gallon water bottles at the Culligan water machine. The water is carbon, RO
, and UV
filtered. I have been using this water for months, and it's been great. I do bi-weekly PWCs on my 10 and 20 gal
. reefs, and weekly on my 3 gallon reef. After doing the water changes yetsterday, I noticed that Xenia in the 10 and 20 were sliming profusely. GSP in the 3 and 20 retracted fully. Today, xenis are shriveled and retracted fully. GSP have minimal extension. LPS
in 10 and 20 are unaffected. Rics in 3 are unaffected. Does anyone know of anything that could have been in the water that could have affected the more sensitive soft corals like that?
