RO/DI System

[Tim Marvin]

Carol, like I said I use a GE RO unit from Home depot with the same results as my fancy one.

Thanks for the info Tim...I'm a wholesaler in the beauty industry...and there are also a limited amount of mfg'rs...but there are "name carriers" for those manufacturers. Makes sense as that is what I do. ;) Appreciate the heads up on that one...

Ken...no prob...been busy myself...I did a 10% water change today...since I have started adding my animals, etc. in the last month and a half, I think I'm seeing what happens when I "need" a water change. Before, since I only had a few zoos...polyps...mushrooms, I didn't have to do water changes as often. My levels are ok...I keep a good check...but noticed in the last few days that my "water quality" wasn't as good. Everybody is healthy and happy in the tank...will keep an eye on the algae. The only question I have now is with good water changes...will these "algae patches" go away or stay? Don't like 'em.. :roll: Or will snails eat it? Will be adding a Lawnmower Blenny here soon...will he "mow" it? ;)

Learning....and appreciate the feedback. Like the thread I started...I am trying to look into a RO/DI system cause I don't think the "quality" of the water I pick up in the machine at HEB is that great...which I feel is part of the algae prob I got. Once I do that, I'm sure I'll see a big improvement in the water quality also.

Unless you recharge them, those *lone* DI unit are expensive to buy and replace.

You've seen my setup, I use RO/DI for my reef tank.

I don't know how this guy on Ebay does it for so cheap.

http://cgi.ebay.com/ws/eBayISAPI.dll...category=20758
United States Shipping and handling US $27.50
Shipping insurance per item (required) US $5.00

His price is even cheaper then AirWaterIce's price. I paid over $200 for my RO/DI setup w/ the RO storage and drinking faucet. He sell out of Canada, so when you convert to US dollar, it might even be cheaper. I'm not sure, probably not.

That price from ebay is even cheaper then the unit from the local hardware store or Sam's club.

I wonder if he uses John Guess's fitting for easy operation/maintenant.

Only thing about this system is the SMALL DI filter.
He only lists it good for 538 gallons of 0 TDS water. Of course the filter is only half used at that point. But even 1000 gallons from a DI isn't that much. Most larger ones are rated at 7500 gallons for a comparison.
Otherwise, a GREAT deal.
$99 for a 5 stage, then $25 S+H, is still a great deal. Even if the DI is not the longest lasting one.

IF this is a re-useable canister, you can do a group order buy in DI filter for cheap couldnt' you?

[Hammer]

It's not a reusable cartridge.
And the ones that are usually have a short lifespan as well.
DI cartridges are re-chargable btw. And the chemicals may be harsh, but at cheap, and looks like an easy process.

Hmm, of course if MAAST did a bulk order on DI resins. That could be a lot cheaper
