The ballasts most people want to control with X10 add noise to the whole system. as do all eelctrical devices on the line. The farther from the source(controller) the more noise you get. In a house with a few lights turning on or off it works. in most cases. I know of houses where that doesn't even fly.. But with a reef tank you may be able to controla few devices sucha s top off pumps or powerheads heaters fans etc. But once you try to put too many items on the system you will start having problems.

Victor.. The whole controller idea is something Shane and I are thinking about. I am still making my little unit for controlling ph's and heaters and fans.. maybe lights.. the rest is a bit down the road. [img]images/smiles/icon_biggrin.gif[/img]
