RO/DI units

I have a 300 gal reef setup I am working on. What would be the best RO/DI system to buy....I want to get the best deal I can but in the end I would rather pay the extra money now then have to upgrade later.

I have looked at bulk reef supply and have debated between the RO/DI 5 plus or their 6 Deluxe.....any thoughts......I didn't know if the extra meters/gadgets on the 6 deluxe are worth the extra $60. I know I would still need to buy a float valve for the 5 plus though because the water is going into a Brute storage container. Links are below.

Also I didn't know if a brand like kent or spectapure is a better del or not. Any help would be greatly appreciated.

I just got a Spectrapure unit and love it. I think they have some of the smallest filter sizes, as far as microns go, and have the best RO membrane. I know AZdesertrat did a test with a bunch of different brands and found Spectrapure to be the best. If you have any questions, he's the guy to ask.

 

I've heard great things about Spectrapure. I got my unit from TB Aquatics, and I really like it. It was a great price and seems to work well!

 

i picked up the 5 stage on bulk reef supply imo its a good unit

 

ive been running a 5 stage air water ice for a few years now and love it. great service they have float kits my tds is always at 0ppm.

 

The Spectrapure MaxCap is the best RO/DI on the market hands down. For a 300 GPD tank I might look at the dual membrane version, I owned one myself and it was awesome. No one else individually hand tests and guarantees their membranes to be better than 98% rejection and mixes their own DI resins based on years and years of testing. My Spectrapure systems have all been over 99% rejection since day one, the current UHE is averaging 99.35% rejection with RO only before DI and my tap water TDS is over 800 going in. Resin lasts almost forever with performance like that.
