I have an Aqua Medic KS-1000 that I used for about a year and a half on my frag system to keep it stirred. I have since shut down that system and am no longer going to need the stirrer. It is rated for 200 gallons and worked amazing on my 80 frag system. The plug dropped and is now pushed in. You could possibly fix it or purchase a new one from battery warehouse or online easily. It sells new for $300 and I paid that 2 years ago. I am asking half that $150+shipping because of the plug.
