seabass Posted January 15, 2019 Share Posted January 15, 2019 Walmart's purple cap (at least that's what they were when I used them years ago), gallon jugs of distilled water are fine to use. Quote Link to comment
Gourami Swami Posted January 15, 2019 Share Posted January 15, 2019 I've been using only distilled water from cvs with no ill effects. Have barely any algae after a few months using it Quote Link to comment
Kellie in CA Posted January 15, 2019 Share Posted January 15, 2019 Distilled is all I have used for 15 years. Quote Link to comment
RemoGaggi Posted January 15, 2019 Share Posted January 15, 2019 I just bought some Walmart distilled water a few days ago. It has the purple cap. I just tested the water with my inexpensive TDS tester and it measured "0", whereas my tap water measures "122" with the same tester. 2 Quote Link to comment
Clown79 Posted January 15, 2019 Share Posted January 15, 2019 I've used distilled from various stores. It's safe to use as long as it's not remineralized. Distilled will say ozonated(that's part of the distillation process) Says 0 fluoride, 0 minerals. If its remineralized it will state it on the bottle 1 Quote Link to comment
Newstead Posted January 15, 2019 Share Posted January 15, 2019 Plain distilled or CPAP water is safe - I have done TDS, nitrate and phosphate tests on them. Just avoid "baby" distilled water - they add minerals back into it. Quote Link to comment
Lula_Mae Posted January 15, 2019 Share Posted January 15, 2019 I used Walmart distilled for years. It's fine. Quote Link to comment
starkschicken Posted January 15, 2019 Share Posted January 15, 2019 I would recommend the "great value" green cap purified drinking water 89 cents / gallon UV filtered, RO Quote Link to comment

Purple cap distilled is a better option. 2 Quote Link to comment

It's not pure. Adding tds and minerals you don't want into the tank. Why switch, the op is using RO water already. Quote Link to comment
jeepseahawk Posted January 17, 2019 Share Posted January 17, 2019 I have used distilled for over 3 yrs, whatever says distilled on shelf at store. My tank is only 24 gal so easy enough. 2 Quote Link to comment
