My sole purpose was to show others its depends on where you live on quality of tap water... time and time again i see poeple vein blasted for using it .. in my area no one uses them.. in fact i hadn't heard of a ro / di unit untill i started visiting this online forum.. don't get me wrong im completly aware of the issues with tap water, however with bi weekly water change and suddle subtrate replenishing I've had no issues.
To each their own.. i just wish poeple would word it as in my area the practice is to use to use ro water or ro/di ....distilled what ever it maybe because of the quality of the tap water.. rather tap water being a big NO NO... not everyone gets their water from the same location .... best bet is for someone to join their local marine aquarium club and see what everyone else uses before proceeding with tap water.
