    I have a Danner Supreme mag drive utility pump, hard plumbed into my sump in the basement back to my display. I needed to fix an electrical issue in my house, and turned off 2 breakers, one of them being the line my tank/pump is on. I fixed the issue, turned everything back on, and all is...

    I am looking for a new pump for my sump. 50g salt FOLR for now with a sump setup in a 20g tall acquarium. The "mag 9.5" has been recommended to me for the volume turnover as well as the low noise output. However, doing a little research, are Danner and PoolMaster Mag 9.5's the same thing...
