I do rinse my frozen always, I'm a big believer in it I'm beginning to think that when I crashed my fuge with the accidental Hyposalinity lazy dumb mistake. That it affected the SB and this is just a result from that. Last night I cleaned out as much of the slime as possible and lowered the timer from 8hrs to 6hrs. Also thinned the chaeto a bit more. As for a GFO reactor, it's going to have to wait for a bit longer. I've other priorities at the moment (Thank You Chuck) LOL.
