I know there some very satisfied Purgen users on this forum. I've used it on and off for the past year with great results. however tonight when I was cleaning out my FX5 the Purigen was a bright green color like jade...I've never seen this before , just the usual brown color indicating it needs to be recharged....Any idea of why this one turned green and it's not algae..Is it safe to recharge?

.I wrote Seachem an email , I'll let you know if I recieve a response...
