The bubble blaster pumps are good IMO
. That was an upgrade I was going to do myself get a bigger bubbleblaster pump for mine but I don't really need it now since the scrubber. I'm trying to remember the model pump I have . I want to say it's a sicce psk 1500 or 2500 I can't remember so I would stay away for that pump . It is a tough decision to make I was lucky enough to get a recommendation from Mr x so I just went with it and It's been great with that one exception .
