anyone ever used one of these?

i never had to use anything like that... what kind of nutes are you using? most nutrients have some sort of ph buffer in them that keeps the water at a pretty decent ph... it shouldn't be moving very much, unless you have a very small reservoir.

Sorry, I couldn't resist ;-)
 
I've found that enlarging reservoir sizes immensely helps stabilize ph. If it's feasible, you'd save a shitload of money.
