Ro/Di Unit

[Gizmoh]

Just looking for some input which would you get?

MC spectrapure (http://www.reefsupplies.ca/online-store/MAXCAP-90GPD-RO-DI-SYSTEM-by-Spectrapure.html)

Or

Vertex Puratek (http://www.goreef.com/Vertex-Deluxe-Puratek-4-stage-RO-DI-System-100GPD.html)

I hear the spectrapure is better unit just looking for a little feedback!

Thanks

Justin

I've been using a puretec for a couple years now with no issues, the addition of the booster pump is a welcome feature and may produce better performance pending on the water pressure in your area.

X2. That's what I use, and I'm very pleased with it.

The aquasafe membranes is rated for 1000 gallons versus the 6000 gallon with other units like BRS. You will be changing it quite often. Take that into consideration.

Where did you get this info from? Their website says the pre and post filters should be changed every 1000 gallons on their aquarium combo system that comes with 6 sets of pre/post filters to last the membrane lifespan.

Membrane, carbon & pre filter change schedules will be very dependent on the source water, which can differ greatly according to where it comes from. i.e. where you live. No sense getting too hung up on numbers from manufactures that are based on specific conditions which may or may not correspond to what will actually happen when you hook their unit up to your water source. Many variables, temperature, pressure, TDS, chlorine, chloramine and on and on. Most units are built using relatively generic components as far as the housings go. Whatever you decide on, make sure the membrane & carbon block are premium quality. The rest of the hardware is generic 10" stuff with each manufacturer simply stamping their name on it. I think some manufacturers individually test the membranes before assembling & shipping their units. This comes at an extra cost & if you're willing to bear that, go for it. For most of us, a brand name membrane will do just fine.

Sorry that is a typo. I didn't mean membrane but on the sediment filters.

Any GE membrane is the way to go for replacements

Just make sure what you buy takes the TFC style as I believe they are the most popular / easiest to find

And, for Justin, I bought a Vertex ( not your linked model ) and am happy with it

I have the Vertex you linked to. 2 years now, never had a problem. It has a booster pump (so I get 1:1 good water to waste water ratio) and a built-in backflush system as well as a built-in TDS meter.

Good bang for the buck.

Any unit will work just fine, I would recommend a 100GPD membrane, and make sure you have DI resin in there somewhere. All the other features may be fun but historically turn out to be not that accurate and to stop working over time...the two units I use now are both bare bones, all produce 0 TDS. I recently bought a few units from the site below, they are in stock and ship quick, they will even do custom stuff at reasonable prices.

I'm looking into an RO/DI as well.

I was looking at either the Bulk Reef Supply setup vs the Vertex )http://www.jlaquatics.com/product/vt-ro100di/Vertex+Puratek+Reverse+Osmosis+Deionization+%28RO+ DI%29+Filter+-+100GPD.html _

I've found these two to be quite cost effective. My small but important concern would be cartridges. Other posters have mentioned that they all they all use standard filters but I'm still doing some research. My TDS out of the tap is about 8 most days so I'm not really concerned of having to replace them right away. Like other posters have said, it depends on your water for length of life of the filters.

I just would hate having a system where I wouldn't be able to find the filters that fit properly or not have a choice of buying filters of other brands or elsewhere (ie will the BRS filters fit in the Puratek system...etc...etc...)
