Just wondering if anyone has used or is still currently using a Sicce voyager 4 power head ? I'm getting one from a friend next week, and I just wondering what to expect. Since it's free, I'm not going to say no. But I'd still like to hear any experiences with this power head. Mainly should I put it in my display or just use it for mixing salt. I'm trying to find replacements for my koralia's.

Thanks
