So my booster pump has up and died and I have been planning to upgrade my entire RO/DI system for a while now. I currently have:
1. 50gpd RO/DI for FWP tank, drinking water, and ice maker
2. two side-by-side 60gpd RO/DI for my reef.
3. one 96g RO/DI holding tank
4. one 96g SW mixing/holding tank
5. one LiterMeter III to dose display reef, and one gravity fed float switch to top-off the grow-out/QT tank.
This systems performs OK but is on the outer limit of my needs. I currently top-off 9 - 12gpd to the display, plus change out 90+g/week, so my best guess is that I use about 200g/week just for the reef. The problem is that leaves me with little to no backup. While I always have the SW mixing tank full and ready to go, that is not enough in any kind of emergent situation and I do not like to introduce "fresh" SW that has not been aged.
Waiting in the wings is a 200g fiberglass tank that I plan to install for RO/DI holding...so enough back-story, let's get to the decision.
I have tried to go "commercial" and been beat back by rediculous prices for not much additional flow.
So I am considering the following and would appreciate any input regardig these devices, their installations, quirks, etc., or any additional units that I should consider:
1. GE Merlin: http://www.ge-merlin.com/ I would install this and follow it with a large amount of DI resin.
2. SpectraPure MaxCap RO/DI: This in theory would increase my output slightly but I just don't think that is is enough. For the price difference, it seen the GE unit would provide a lot more flow and lower the efficiency of the DI resin slightly.
Please keep in mind that this is for a large system that may grow, and simplicity is a good thing! Any coments?
