Does anyone have one of those RODI under the sink kits with tank?

[larryandlaura]

Im looking into the RODI kits for under your sink with storage tanks. I can use it for drinking water and topping off my reef. I want a 75 gpd with a 55 gallon storage tank. Any suggestions? And should I just go with a 90 gpd and a storage tank in the laundry room?

[Kmurraylhs]

I am very happy with my system from Air, Water, & Ice. I have two 55 gallon drums in basement one for RODI water and one for saltwater. Makes water changes a breeze. I am thinking of purchasing a storage tank to hook up the frige to it.

[larryandlaura]

Gotcha I want the one with drinking water. The best of both worlds.

[Kmurraylhs]

They sell those too.

Yeah Im looming at the typhoon kit. I was wondering if anyone has one here on CR?

I sold a Typhoon III to buy a Spectrapure system and have never regretted it, no comparison in performance or cost of ownership.

You will find is is cheaper and better to buy a reef quality RO/DI with a drinking water kit rather than buying a drinking water system and trying to adapt it for reef use. My first system years ago was a Watts Premier from Costco that I eventually modified for my reef systems at a much higher cost than if I had bought a ree fsystem to begin with. The filters are different quality, the membrane is usually a different GPD and often quality, you need to add an additionl canister ancartridge for the DI plus things like tees, check valves and more and it adds up quickly.

I started with a Typhoon (under-sink), but purchased a larger BRS system (http://www.bulkreefsupply.com/store/75-gpd-ro-di-5-stage-deluxe-system.html)exclusively for reef use. Much better overall performance.

I agree with AZD, it's better to add a drinking water kit (http://www.bulkreefsupply.com/store/products/reverse-osmosis-filters-and-systems/reverses-osmosis-deionization-systems/drinking-water-systems/add-on-drinking-water-kit.html)to a high quality RO/DI.

Ok thanks everyone.

I'm looking at the hurrican dual home/reef from air water and ice. Upgrading to the 5.2 gallon tank though. What do you guys think?

[AZDesertRat]

You can do much better.
Looking at it you see it is only a 50 GPD, vs 75 or 90, uses a very coarse sediment filter about as effective as a screen door so has to use two carbon blocks to trap what it misses, has a small horizontal throw away DI filter, uses the less efficient fixed flow restrictor, all pretty lame.

Compare that to a true reef quality system with a 0.5 or 1.0 micron sediment filter, a single 0.5 or 0.6 micron carbon block good for 20,000 gallons of chlorinated or chloraminated water all by itself since it is protected by the better sediment filter, either a 75 GPD or treated and tested 90 GPD RO membrane, a true 10" vertical refilable DI filter filled with reef specific DI resins, a capillary tube flow rfestrictor, an inline pressure gauge and more.

[larryandlaura]

Gotcha so I guess ill order a rodi that's 90 gpd or better.

DO NOT buy a system with a 100 GPD Dow Filmtec membrane, its the worst possible choice you could make. Its only 90% efficient versus 96-98% efficient. The reason this is important is for ever 2% you reduce the efficiency, you cut your DI life in HALF. A 6 to 8% decrease would get very expensive in resin replacements.

THe 75 PD Dow Filmtec is the most popular choice of membranes by probably 100 to 1. Spectrapure starts with that 75 GPD then specially treats it and tests it for quality control.

+1 Great advice!

Great info as always...thanks AZ

Thanks for the advice. Im looking at a spectrapure 90 gpd. Doing a little research and getting some much needed advice. Thanks all for the input.
