    Fwiw, knowing what we know about rodi water and how reactive it is, I just store my test tubes filled with rodi water all the time with the lids on tight. When it’s test time, I rinse them with tank water as to not have any dilution in the sample.

    I have these and they have worked out. I like DIY, but time is limited.

    Somewhat off topic, but I have a small pump and about 8 feet of hose that I use for water changes. I recently noticed what looks like mildew in the hose. I soaked it in vinegar and it cleaned it out, but I need a way to dry the hose to prevent things from growing in it again. Anyone know how to dry out 5/8″ ID vinyl tubing?
