RO/DI System

[NC Reef Guy]

I am looking for an RO/DI System. I see various mentions of sytems but am lost in it all. I will have a 120 gal tank, and just need to make the initial water and then just the water for water changes and such, so I don't think I need a huge number on the gpd, but I'm not sure. I heard that the higher the number the lower the quality of water coming out, but again not sure if that's right.

Filter guys, kent marine, spectrapure are the ones I've seen but don't know one from the other.

So I'm looking for some input and/or reviews of systems that people have. Looking to stay under $200 on this system, if possible.

Thanks for the help.

Depending on the amount of water you're making, how bad your local water is, and if you have chlorine... excess stages are not necessarily a good thing.

...and your water pressure is key too. Mine is 45psi and despite what some "experts" told me, it is not enough and I had to buy a booster pump to get any realistic production (i.e. my unit is not hard plumbed so I can't leave it in the tub for 14 hours to make 4 gallons) and be careful with the waste water ratio. I think I clogged my membrane because I didn't know how to use the restrictor valve so I had to shell out another $60. for a new one. I have the Aquasafe Maximus from ebay.

I might also add that it works perfectly now and produces close to 100 gpd at 000 TDS. For about $40 you can also get a dual inline digital readout TDS meter that takes all the guess work out of "bad" water to "good". I've learned all of this a bit late, good luck.
