A couple of weeks ago I bought about 30 gallons of RO water like I always do. (I haven't bought a RODI system yet) I usually use the water for top-offs during the week and changes once a week on my 37g tank. I have been noticing that my green watermelon mushroom colony has looked bad, all shrunken. When I went to do a water change, I put 5 gallons of water in a bucket, put a heater and power head in and added the salt. I let it run all day. Last night I checked the salinity of my tank and it was way high! I then checked the water in the bucket and the swing arm went all the way to the top! So... I checked the water in my containers and what do you know, They gave me already mixed saltwater instead of RO freshwater and I have been topping off the tank all week with saltwater! I never thought to check the salinity of the water. I had to break down and treat tap water last night to bring down the salinity. I hope that my mushrooms recover! Everything else seems okay.
So, if you buy RO do you check to see if you get what you ask for? I definately will in the future!
