I don't really want to shell out 250 dollars now for a ro/di unit is it ok to buy distilled water from the grocery store?? I was even thinking it may be easier to have it delivered for like 5 dollars a 5 gallon container.. From my understanding of ro/di units you have to change the cartridges every 50 gallons or so. When you factor in the cost of that wouldn't store bought water be pretty close to the same cost?? about 1.00 a gallon or even cheaper when the water is on sale.

Distilled water will work just fine but test it before you put it in your tank. If you have an LFS see what they are getting for RO/DI, it should be anywhere from $0.25 to $0.70 a gallon. I pay $0.29 a gallon at one of my LFS. I have a 55 gal and evaporate 1 gal a day so it can get pricey if I were paying around a buck a day.

Not so. Cartridges should last around a year depending on how "dirty" your water is. Depending on your needs you can get a good unit for much less than $250. Still cheaper in the long run to get your own filter by the time you factor in the price of gas to get the water, time spent, etc, etc, etc........

I already rue not getting an ro/di unit. It's actually my next purchase since i've almost spent enough to buy one on WATER. lol

Wow! I am really getting ripped off then . The only place around here that sells RO/DI water charges $0.97 a gallon , so I had nothing to compare the price to. Thats how I have had to buy it. I can't wait until I can afford an RO/DI unit. lol.
