    No. Depends where you are. But rain drops pick up various nasties from the atmosphere. And bird crap from your roof too.

    The only time you can safely use rain water is if you still put the water through a RO unit.

    There are a couple of reefers that use rain water but firstly they check the TDS of the water and if it is under 10, then only use it, secondly it has to be collected in a way that no chemicals get added IE: roofs, gutters etc.

    So generally it becomes more of a difficult exercise than it is really worth.

    Guys just remember, all these creatures and fish that we keep in our little glass boxes once lived a happy life in the sea with no "bad" water quality and people experimenting with water etc.
    Please, if you wanna keep marine creatures then use the best water possible to keep them happy. Just as you would like to drink clean water and bath in clean water let your fish and inverts live in clean water.
    They didn't ask to be there in your tank in your house, so the least we can do is by providing them with the right type water - RO WATER with a TDS of 5 or less.
    If you're not prepared to buy a RO unit or buy RO from a LFS, then don't keep marines!

    and this is not aimed at anyone specific - it is just my general opinion ;)
