The Opae ula shrimp Forum and online store

Hi there. I'm planning to set up my first opae ula mini and I read you can use RO water or distilled water. The only LFS in my district that sells RO water is a few km away and I don't have a car, so I'm thinking of using distilled water. My supermarket sells distilled water intended for domestic appliances and car batteries. No fragances or other additives that I can see in the label (they also sell a fragant one intended for ironing). My question is, can I use the "normal" distilled water intended for car batteries? Many thanks.

I use "Car Grade" distilled water from Tesco for top ups and it's been fine for ~3 years now. Just mark your tank's level with a marker pen, and make sure you slowly top it up via the drip method.

Ok, thanks!
