Is this RO Unit worth getting?

SpectraPure® CSP RO System Details

Seems like a deal but I'm not very knowledgeable of RO unites. I have a 75g FOWLR and plan to keep it that way for some time, no coral or anything like that, will this fine? I've seen others with more stages, so I’m not sure if this isn’t enough or will be okay. I've never hooked up an RO unit before, is this easy, could I simply hook it up under my sink or something?

Thanks
Dave

No. I don't think it is. Find a unit with DI as well. RO alone cannot get TDS to 0. More importantly it can't remove all the silicates in the water alone. If you get this unit you're going to be kicking yourself in the butt for not getting one with an accompanying DI unit (like I am now)

Yeah I just noticed it didn't have a DI stage.

Something more like this?

Captive Purity Deluxe RO/DI Filter System - Clear Canisters

It's 35 gallons per day, but 25% water changes on my 75g is right about 20 gallons, so I'd imagine this would work out okay.
