Ok here is the deal,

I work for Oldcastle Glass and we have all kind of different glass type, some have a special coating that requires special water quality, well to my surprise i just discover we have an enormous water system, i knew we had but i never care before i had a marine tank, so it looks like a ro/di unit, well, the shape of it but its like 1000 time biger !!! on the low settings it produce 20 gph, but i dont really know if its ro/di, so is there a way to know it, even if it is one, what kind of test can i do, like PH GH KH NO2 NO3 NO4 etc, can i test it with the water test kit i got ?

And if it is a good water source and i want to change my water how can i do this in a 20 gallons tank that is 2 weeks into the cycle ?

Thanks for your help.

Gee.

check the GH, that will tell you if its a water softener or RO unit. (sounds like its a water softener)
