Ebay RO/DI filters

[catfisher]

I'm looking into buying a RO/DI filter. I've been buying jugs of RO too long!

This is one that I'm looking at on Ebay...

They sell these at purewaterclub.com as well.

Does it look like a good filter?

Anyone?

I would pass, for numerous reasons.

First, it has a horizontal DI chamber, which allows for channeling -- not a good thing.

Their math is very suspect,

to removes 98% to 99.99% of all chemical and harmful dissolved elements and 99% of all bacteria

And yet,

Water Purity Reference: (1.)Tap or well water(300 PPM), (2.)After RO system(20 PPM)

That would be a 93% rejection rate, not the 99% that they listed in my first quote of theirs.

Would be better off getting an unit from one of the sponsors.

I'm not sure about that one, but this is the one I've been using for almost 7 years now. Mine only has the 1 DI and came with a carbon at the end, which I removed after it was spent. I also turned the DI resin, so it flows vertically up. Every year I buy standard replacement filters. No complains from it. And it was much cheaper than the Reef name brands.

The PureWaterClub RO/DI units are popular, but not the best quality. You do get what you pay for. On the other hand, they do work.

I have been using a purewater club unit for almost two years now. I'm currently setting up my first SW tank but all the water I have filtered (45G per week) has been used on my 72 bow front planted FW tank and my 8G planted FW Painted fire red shrimp breeding tank. I love these units!!!! I have never had any problems with my unit EVER. One thing I would look into is getting either a hand held or an in line TDS meter.

To handle the channeling comment....I have had this happen with mine but if that's the case you haven't packed in enough resin. When you get the right amount you will not have this problem. Funny thing is that the filters the company sent me with the unit I think were better than the ones I purchased after they were spent (mainly the DI resin). I find that the resin provided by the company when I initially purchased the unit lasted almost 8 months before sending out water with recordable TDS. After it ran out I purchased DI resin from BRS and it maybe lasts a month before changing colors and becoming exhausted.

I like that the eBay one (a few posts above) has two DI canisters.

I don't like that it has one 5 micron sediment filter, and then nothing smaller. That leaves a lot of junk to plug up everything else.

Thanks for the input guys!

I use this exact one and like Falconut, placed the DI canisters vertically. 0 TDS water is the goal. So as long as you get that, you are good. I'd also invest in a inline TDS meter so you can tell when you need to change something. Clear housings are also a MUST IMHO.

I also use these replacement filters.

Works pretty well and averages about $16 bucks per replacement set with Free shipping. I Get the DI resin from BRS during a group buy.

if i was going to purchase one id go with the vertical canisters,i currently use a spectrum new life max cap system,i guess your getting a decent filtration system for the money,but i believe in spending a little extra to get allot.also 5 microns may seen tiny but the .5 micron carbon blocks remove much more sediment.
