I have just started a 14g nano tank, and I am wondering if I can use store bought distilled water for the water changes--until I can afford a RO/DI filter
unit?
I don't see why not as long as you know that the place you get it from is a reliable source. Also, if your interested I have a 3 stage 24 gpd Coralife RO unit for sale. Just shoot me a pm. LMK.
