Topping off with distill water.

[locnload]

I've been topping off my 12 gallon nano with distill water for sometime now. I don't need to use very much because there's not that much evaporation.
Anyhow, does anyone see a potential problem with using distill water to top off?
Thanks

I use distilled water also and have not had a problem with it.

I don't see a problem either .... second choice behind RO IMO.

I Was using distilled water for the longest time it never caused a problem i don't think but i just recently swapped to RO water and everything seems to be doing better and the water looks crisper...it's actually cheaper too. I just saved a caralina water 5 gallon box and fill it up at the LFS everytime i need to.
