Compare RO/DI Units

[chromakey]

Good Day:

I have been looking for a RO/DI unit for my two small saltwater aquariums and for home use.

I am considering:
Vertex Puratek,
Aquasafe Systems, and
Spectrapure.

I was wondering if anyone has good experiences with one type over another.

Thanks,

Michael

I have the Aquasafe system, I use a 55 gallon storage tank for the RO tank water and also have a drinking water tap.

The Vertex unit makes all of those other ones look like they were engineered by grade school students.

Seriously, best value out of an aquarium-related product on the market, BAR NONE.

got my vote

the vertex come with booster pump, nice tds meter, auto flush in one package so it got my vote as well.

Really? I just bought and installed a Spectrapure MaxCap 90 from Reef Supplies. I had in installed in less than 30 minutes and was cranking out 0 ppm TDS water in bucket-fulls in no time. I can assure you it does not look like it was engineered by grade school students. Seriously.

It's fine to offer a system with a booster pump.... but if your house water pressure is better than 60-70 psi, you don't really need one. In my area the water pressure delivered to the house is between 110-120 psi and the plumbing code calls for a PRV in the house to regulate/reduce that to the standard 60 or so psi for home plumbing. By tweaking the PRV I have 100 psi going into my no name RODI system. Why would I want the added complexity & expense of a booster pump?

As I mentioned in my previous post, a little pre planning & research into what comes into your house can save you from spending extra money you don't need to. I suppose I should add that my no name system was purchased from an outfit in Ontario that's no longer in business. Despite that, it's still a great set up for my needs with standard 10 inch, clear pre filter housings, a DOW filmtec 75gpd membrane that's still going strong after almost 4 years & thousands of gallons produced with a tapwater TDS of approx 210-220. It doesn't take a rocket scientist to put together (or design if you wish) a RODI system using generic components that have already been designed & have been on the market for many moons. It really boils down to the quality of a single component, the membrane itself & possibly the carbon block.

I'm not really a fan of the auto flush feature either. I flush manually before & after each production run & that's served me very well over the years. Auto flushing too often uses up your carbon while wasting water down the drain. I've also found that at each flush, there is a TDS spike which takes a few minutes to get back down. All the while, your DI will be working harder to give you that 0 TDS you want for your aquarium.

Yes, seriously.

What makes you think the Vertex isn't 100% better than the Spectrapure for the same money?

Compare:

http://www.reefsupplies.ca/online-st...ectrapure.html

• Four stage RODI
• Two Dual-Probe Inline TDS meters
• Manual flush valve for longer membrane life
• Auto shut-off with float valve

Okay, so consider that the Vertex has that plus the following:

• 1:1 water ratio
• Automatic backflush control and membrane monitoring
• Solenoid controlled back-pressure sensor
• 100% unit shutdown when unpowered
• Local Canadian support

For the $20 difference, I'd say that is a much better value and a much better product.

I'm very happy with my Vertex. Worth every penny.
