Water Change Question

[bigsnuff]

I cannot afford a RO unit at the moment. I just put out quite a bit of money for a new protien skimmer and light setup. Would it be ok to use Distilled water to do my water changes? I have a 90 gallon fish only tank and like to do a 20 gallon change every month. Thanks!

You'd be better off to buy the RO/DI water from the machines in front of WalMart. It's cheaper and RO is more pure than distilled. There is also the probability that the distilled water was distilled through copper tubing, which could accumulate in your tank.
