Best RO/DI unit and why?

[Pigpen80]

I have a 55 gall reef setup and I am purchasing a unit tonight based on the feedback I get.

What is the best unit to get in all of your expert opinions?

I was thinking around 75gpd. Is it beneficial to have a membrane flush valve? What about a pressure gauge set up?

I have scoped out: the filter guys, air water ice, buckeye field supply, and marine depot.

I am hoping you guys can give insight to the unit with the most bang for your buck, and honest feedback regarding the best company to buy from for service.

I would like to stick with a business that goes out of their way to support all of us reefers.

Thank you

Flush valve will greatly extend the membrane life, imo. I flush for 1 minute before each use & only use the unit once a week. I make enough water for top off & changes. I'm on about 10 months & readings are still 0-2ppm.

I'm partial to Bulk Reef Supply. Their products & customer service have served me well. They have a good rodi unit & supplies are reasonable & can be bought in bulk. They also have some good videos that explain their rodi & many other products they sell. It's worth checking out. Otherwise any of the 1st three companies you listed have a good rep on here for their rodi units.
