Distilled water?

[SigEpLucas]

Are there any negatives to using distilled water in a reef tank?

I think it's a little less pure than ro/di, but you'll be fine using it.

Distilled water if fine.

I was thinking it was more pure than RO/DI water.

Dunno, maybe.

But whenever I see someone ask which of the two is better to use, people always say RO. So I just figured...

They are just different ways to get the same result. It is just that there are home RO units so it is a bit more available. Distilled water is water that has been condensed from a steam so since steam isnt capable of holding impurities, when condensed, it is pure water

Aluminum machinery is generally used to produce distilled water and your might get some high levels of it in the water. Oceanic salt already has high levels of aluminum in it. But I've never heard of anyone having serious problems with aluminum. Isn't it kind of expensive in those 1G jugs at the grocery store?

it is 99 cents a gallon but so is the ro water at the lfs and the guy that works there is a @$$hole so...

I only use distilled water for water changes and top offs. My tank has been doing just fine so you'll be ok.

For the first seven yrs of my reef tank I used distilled for top offs. It`s much better than tap but not as good as RO/DI.

Distilled is fine to use, as far as being better then RO I guess that would depend on the RO system, a 3 stage system will deffinatly not be as good as distilled etc.

You are looking for the least amount of TDS "total disolved solids" its best to be below 5
