RODI vs DI water

[cestep6]

Hi Folks,

I"m setting up a 180g Reef tank.

My issue is that I'm space limited for storage tanks for and RODI system. Most systems I'm finding will create 75-150 GPD

Does anyone have a suggestion on a system that I can use that does not require tank storage? In other wards that has a direct in/out that I can use on demand?

I do have one company who delivers Ultra purified water (12 stage filtration, UV sterilized) in 5 gallon bottles.

Any ideas folks?

Thanks,

Carl

If you can store their 5 gallon buckets why cant you simply store the RO/DI water in a 5 gallon bucket? It's not a good idea to run your RO/DI water directly into your tank with a float switch, when you make very small amounts of RO/DI water it uses a lot of resin because a lot of impurities get by the RO membrane when it is just sitting without a pressure differential. There is also a big risk of overfilling your tank with fresh water if the float switch gets stuck.

I agree with the above. FWIW I use a 30g brute can for mixing and a 10g for the ATO. My RO/DI is a 75GPD unit.

Let me clarify, the bottles would be delivered when I'm ready to do a water change. Once I do the change, the company picks up the empty bottles.

That sounds fine for planned changes. But, there have been a few times of the years that I have needed water in a hurry.

Gone, you hit the nail on the head. is when I need the water in a hurry.

I've gotten suggestions from others to you a portable DI water tank, but not sure that's cost effective. The ones I've found are for car washes and don't look like they last long.

Has anyone used this "ultra purified" water? not sure how it compares to RODI water.

Thanks,

I am curious is it the actual RO/DI unit that your space limited on or containers???

Before I was able to keep RO/DI & storage area together. I stored a brute can on one of those wheeled platforms made for the cans in my garage. I would roll it around to the RO/DI to fill and mix then roll it to the tank for the WC. Hope that is not to confusing.

It's the container storage that's the issue. I don't have the room to do a storage tank that can store the water until I need it.

The reason why there is a need for storage container is 75/150 gallons sound a lot but it takes a long time to make that much water. Takes about 45mins for me to make 5g and that's with the 150g upgrades.

Look at it like this, your tank fails, you need 45 mins to make 5g, then an hour to mix the salt(should be much longer but emergency scenario)That's 2 hours before you can change just 5 gallons

Gone,

This is why I'm trying to find an alternative to the storage tank solution and looking for an on demand type of system. I've learned the hard way with my 75 gal reef that treating tap water is not a viable option.

I kept one of these in my garage when I live in Connecticut. I insulated the outside of it and had a pump in it to recirculate during the winter. I would fill the 30g brutes then transfer to the tank. Pull of the tank when needed. It was a PITA but it worked.

Forgot to mention they have other sizes and shapes as well. Maybe one could suit your purpose??

Thanks Tony, wish i had the room for a tank like that.

How can you not have room for a 5 gallon bucket of water I am so confused. You don't have room for an 18 inches bucket 22 inches high Think that's 28 gallons.

Someone may be able to correct my spelling, but a very successful LFS here used a Kold-Stero system that required no storage for their Reef systems. Bertoni may be able to clarify and advise.
