if you have a chance to use aged tap water, than its ok. With Moina I use mostly the water that I get out of my tanks when doing water changes. Its still ok for Moina. I just add a little tap water to make it less acidic. I do that becouse cross contamination with other food organism from my tank never caused problem with Moina. On the other hand I never do that with Rotifera cultures, as mainly cross contamination with Moina can destroy the culture very fast.
