    Yes, I killed about 40 adult fish by adding rain water.

    Re: Ph going down!

    if the ph is caused from particulates such as salts, calcium, magnesium etc the RO will remove a percentage of these compounds (membranes are designed for specific applications, they can be designed to remove from low percentages of compounds on to up to 99. 75% of a particular compound. they are used for seperation of whey, removing dyes, detergents and on and on) removing the buffers will create water with a neutral ph. If the ph is cause from chemicals that are too small to be removed, but will pass through the membranes, such as some gasses in solution and solvents, it will not be able to correct that problem.

    they were originally designed for desalinization, there are membranes made from both organic and non-organic compounds. if you do go RO make sure you have a system that reprocesses the water more then once with a recirculating valve, you can have a system that can recover up to 75% of the water otherwise you will be wasting most of the water.
