Sorry to derail your thred Mike however here is the mods
Mike I changed to the second Water blaster and all I can say is wow. My tank is DEAD quite and seems to push as much or more water than the magnums. I am sold!
So are you still liking the Water Blaster pumps? I'm in the market for a couple new ones for my 300g as well. have a reeflo on it now that is way too loud, bought some quiet ones but they are loud so into the fish room they went
Specs on the water blasters look pretty good!
