Filter sock makes skimmer go bizzerk

[Coralgurl]

I was cleaning out some stuff and came across a new filter sock. Since I'd been lazy and hadnt washed my other ones, thought I'd throw in my sump. Well my skimmer went nuts and immediately started to overflow. I pulled the sock out within a few minutes but the skimmer still hasn't settled down. It's been well over an hour since I did this. It's a vertex sock that comes in the box.

Socks are in the washing machine now. Is just because it's newish??

There might be some manufacturing chemical on new filter media socks,filter floss,pads etc.Temporary and most likely harmless.

Things have settled down now and all is good! Thanks

This always happens with my new-ish filter bags. Once I've washed then 8-10 times they don't do that anymore, bbut for the first several washings they do mess up the skimmer for a few minutes.
