this is the most trouble i have ever had with a skimmer :angry .. it's the Aqua C EV120... twice now it has gone nuts and dumped 5 gallons of water on my floor and my ro/di has replaced it with nice fresh water (of course while i'm at work for 10 hours :blink ). i don't get it..... it will run producing almost no bubbles and then out of nowhere skim out over 5 gallons in just a few hours. it is an injector style and i have tried overdriving it ,underdriving it.. it simply will not produce a stable foam.. its either nothing ,, or 5 gallons.... :wacko does anyone know if they smell bad when you set them on fire? it's 3am and i don't want to wake the neighbors
