View Full Version : media and soleniod

I want to make a large media container to hold phosphate remover and carbon. I don't want it to run all the time and I would like not having to replace the media every week. Has anyone used a solenoid valve to control the flow through the reactor? Any suggestions?

You could just put the pump on a timer, but I'd be afraid about the water in the container becoming contaminated with anaerobic decay compounds if the flow is turn off for too long. Maybe three hours off at a time would be fine.

That was my same concern.
