Have a new 45 tank but live a long ways from a LFS. Thinking of taking the plunge (yes the pun was intended) into a RO/DI Unit. I haven't a clue how to evaluate. I of course don't want to spend anything but I don't want something useless either. LOL Any good advice?
 
Thanks guys. I have a pull down decorative faucet in my kitchen so will have to go with the garden hose. But that isn't a big deal. I already adapted the cheap filter I bought at Lowes to fit the garden hose.

Here are another couple question for you. How long do this unit take to make about 5 gallons of water? How much waste is produced? To make 5 gallons is it using something like 7 gallons? Not a big deal but just curious.
 
It takes me about an hour to get 5g of water. The waste is at least 3 to 1 though. I fill up an entire 32g garbage can in less than 6 hours. :)

You wont need an adaptor if when you order you tell them to include it, they give you one for free. :)

If you are using the garden hose you can run the waste water to your flower beds or lawn, thats what I do.
 
Good info. Thanks. Now I just have to figure out where I can store water. Garage would be easiest but with 110 degree heat in the summer and below freezing in the winter that isn't a good option. LOL Guess I will have to take over the coat closet off the kitchen. My wife is going to love me. Oh well, I can always fall back on "It is your birthday present dear". Hehehehehe
 
I keep mine covered on my outside covered porch. I do get alot of evaporation but the lid keeps most of it in.

With a 45g tank you should only need about 10g a week taking into consideration top off water as well as water change water. :)

I have 5g jugs that i keep in the hall closet as backup for my garbage can of water, it's my just in case water. lol I'd look into those jugs. I got mine from an lfs that sold water for like $6 a piece.
 
Home Depot has 5 gallon plastic buckets with lids for like a buck or something. I was planning on picking up some to help with water change and dirip acclimation. I may just get a couple extra and do my water in that. One for old water coming out, three or four for new water storage and one for acclimation. I was beating my head against a wall trying to figure out the best way to do the drip acclimation until I saw an LFS doing it. He angled a 5 gallon bucket so the water collected on one side then used an air line and two way air valve as his siphon. Needless to say, I bought air line and valve before I left the store. LOL Cost me all of $4.00.
 
Home depot also has in the paint department buckets which have the gallons printed on the side for easy mixing. I have 4 of those for out water and four for ingoing water. For acclimation they have smaller painters buckets, maybe a gallon or a few quarts that I use. The lfs never gives you enough water so it will be really shallow if you go with the 5g buckets. :)

just another tip I picked up. lol
 
I was thinking of the paint bucket but my concern was that it might fill up too quick while drip acclimating. From what I have heard you need to drip for a least a couple hours right? (was getting ready to start reading up on that since I am finally about to start adding some fish). :) My other concerns were "Jumpers" but I figured I could cut a hole in the lid to run the drip line through and that would stop jumpers.
 
I just dump the water if it get too full. I acclimate fish for about and hour and a half and shrimp for at least two hours. :)
