Culligan RO water machine mishap?

[nanoluvr]

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?

Below are pics from tonight

What are your water parameters?

Here is one more pic from tonight, and then some healthy comparison pics....

What are your water parameters?

I just got home, so I haven't tested...I'm about to. Prior to the PWC.... ALL tanks were Amm - 0 Nitrate - 0 Nitrite - 0 PH 8.3- 8.4

 

[nanoluvr]

I was worried it could be something that I can't test for
Chlorine or something...

 

[nanoluvr]

ok...just did a test on the 20.... Ammonia, nitrate and nitrite..Zero ppm, and PH is 8.4

Hmmm, I'm not really sure, maybe they need to change their filters....
Did you do anything different, like not heat up the water or let it aerate?

 

[nanoluvr]

exactly the same. Nothing changed at all

 

[nanoluvr]

The Xenia worries me. I'm afraid I may have to scrape it all out of there.

Chlorine is a thought, like you said. I know it is kind of late, but if you can get your hands on a swimming pool Cl2 test kit, it will tell you if you have any in your water. Not that it will be accurate, but you would expect to see none....


Heck, if you have any prime lying around, add it.

Good luck!

 

[nanoluvr]

Yeah...I'll have to wait till tomorrow...I live in the sticks.

Is this the first bunch of saltwater made up from a new bucket or bag of salt?

 

[nanoluvr]

nope. I used this same salt last time. Reef Crystals. I mean...It is a new container, but I opened and used last PWC. No Negative results.

I have also used culligan water in the past with no problems, I agree with sparky697 and put in some prime if you have it, can't hurt anything.
