RODI

Does anyone suggest a good RODI unit that can do about 150 to 200 gallons a day?

Honestly, I would start over before spending any money on what you have since it is a nonstandard system and would cost you much more to modify or upgrade than buying a new reef quality RO/DI system for $125-$150.

Do you really need that much capacity?

Keep in mind you need 65 psi to operate a dual membrane system.

If you can get by with 90 gpd it's $125 or $160 with a complete set of replacement filters plus DI cartridge, a low range chlorine test kit and a handheld TDS meter.

There is a link to the second one mentioned above in post #2.

I have the RO Buddie 100 gpd which I can get a bit more than that. I've known many to get BRS units which has a few you can look at. Like someone mentioned, PSI is key. I learned that when I first purchased a unit. There's a bunch of options just consider price and look at reviews. Good luck

Thanks for all the help everyone we are thinking about a 75 GPD system but we are going to shop around

Unless you have a huge reef or space constraints on being able to store water I would stick with the 75 or 90 GPD system. Dual membranes have their own issues and needs. If you really want more than a 75 or 90 the best way to do that is with an Aquatec 8800 RO booster pump, you can just about double the GPD and best of all is it also increases the rejection rate so DI lasts longer too.
