this might be the stupidest qestion i have ever asked but oh well,,,,well how do you know where and how to connect all the parts like is there a instructions page
no kidding
but if you are looking to hook up an ro filter
it just gets hooked into your plumbing(cold water line) and nothing else, yu then use it to make change water for the tank, but do not hook it up to your tank, you just dispense from it and then make up salt water, then after aerating for a day or 2(at least), you add this water to your tank
don't know if that helps you any
I don't believe there is any such thing as a stupid question, no matter how simple it may be---but you do have to ask it in way so we can help-no one has any idea exactly what equipment your talking about and what exactly you want it connected to----you're going to have to spell it out a little more clearly--I'm sure someone here has had experience with whatever equipment you're working on. God knows there is alot of equipment that goes into these tanks of ours-with a million different tubes and hoses, and valves--the back and bottom of my tank look as bad as behind the entertainment center or computer!!
I don't think anyone meant to sound mean but you need to give us more to go on.
Good Luck
