this might be a stupid question but I will ask anyway:

I am now in a good routine with my new RO/DI unit hat I purchased from air,water & ice two weeks ago and I have a couple of simple questions.

1. if I filter water and store it in capped 5g jugs, is it alright for the water to be stagnet? and how long can I store it at room temp?

2. the oceanic salt that I use seems to mix very fast ( about an hour or so ) how long should I wait before using the freshly mixed saltwater for water changes?

thanks!
