Adding purigen melted my softies?

[Jr'sReef]

I added purigen to my tank about a week ago. That’s the only change so far in the tank. I removed GFO and added the Purigen. For the last week my gorgonias have been loosing their tissue, my Xenia are melted away, and a soft coral that looks like a broccoli completely melted. Does this sound right?

I’ve run purigen and not had a problem with my softies. What are your water parameters please include phosphates and nitrates.

I've use purigen without problem but I never reuse it soaking in bleaching water.

 

[sfin52]

I have reused it and it works like a champ no issues.

Will get it tested an report back

I would imagine it was the alk if it was really that high

 

[sfin52]

I bet is the alk

My money is on the Alkalinity. Should be between 7 and 10...

The only thing the Purigen might do that is likely to be a potential problem is, like GAC, possibly reducing the yellowness of the water quickly. That can result in a sudden increase in the light intensity penetratign the water, and might shock a coral.
