Can anyone here recommend a very high output RODI system? I've been using a 300 gpd "Mako" model from AquaFX with a booster pump (I'm on well water). Works just fine, but I'm filling two 300g storage tanks and need to do so in much less than 48 hrs if at all possible. AquaFX has their "Blue Marlin" model, but before I just sink another $1k + into that I thought I'd see if anyone had any better ideas. Thanks in advance!
