OK....just my 2 cents here...

Nobody has yet to mention the safety issue of having ph's placed in the tank. Can be a "shocking" situation if something faults and you do not have the right protection in place (GFI outlet for example).

I am a "purist" as well when it comes to tank appearance. I would rather go with a cl and a sump than have a single ph or heater in my display tank (which is the way I am planning my 90 g).

As for current...does anyone here run a SCWD cl? Is it worth it?
