A question about RO Units...

[jmerk]

Hey, I am planning on setting up my tank in a few weeks and I have heard that I should get an RO Unit. I was wondering if really NEEDED it. I know of a good one that does 10 GPD, which is enough for the tank I'm getting (2.5g) I don't know if I should get one or not, they are quite expensive and my budget isn't that big

So I am not wanting to get one. Could you tell me EXACTLY what they do and their benifits. I would also like some alternate methods too (if there is any).
Thanks
Jmerk

If you are only going to have a 2.5 gallon tank///IMO it is not worth buying a RO system. Just buy water from LFS if available.

yea get the distilled water or at least the reverse osmosis but not the natural spring.

At the rate that you will be using RODI water for your tank, it doesn't pay to invest in a purification unit. You can buy RODI at many stores such as WalMart, etc, or from many lfs. But - don't get lazy, always use RODI!

For that size tank you could buy your water in one gallon jugs. One gallon would probably last you a month or so.
