I just do 50% pure RO water changes until I achieve the desired TDS. This can take 3 or 4 water changes...
I have a breeding pair that I want to reduce the TDS in the tank from @ 300 to 60-70 for breeding. I have a RO system. How fast can I drop down to the 60-70's - and not harm the fish.
Thanks,
John

I have dumped fish from aged tap into 100% RO without ill affect. Don't worry about it just do what you need to do to achieve the TDS you are looking for.
