I've been running this thing since mid July and so far it has worked flawlessly. You just need to figure out the dosing. The timer has 2 settings, A&B. Setting A allows you to dose 1-4 times daily, but each dose must be the same duration. For my 18'rd using 12.5%LQ, I'll either let it run for 4min. in the morning right after the pump comes on, or I'll have it run 4 times for a minute each time, spread out during the day. Setting B allows you to give another bump either daily, every other day, 3rd, 4th, day etc. If you want to add more because of a stretch of hot weather or a pool party it takes literally seconds to change any settings once you learn how to use the timer. Although you need the timer you have the option to buy without it, it's just an Orbit sprinkler timer you can get at HD or Lowes, but I'm not sure if it would be cheaper that way. If you have an AGP with a short amount of head, you will need to restrict the flow, just like some people needed to do with the Liquidator (see my previous post). The timer needs to be protected from the weather so there was some digging involved, in my case to the shed where I have an outlet inside. The other expenses I had was a roll of thermostat wire, a couple of bullet connectors, pvc conduit to go from the timer in the shed to the unit by the pool and a 5ga bucket with refillable lid, bought mine here

I would definitely recommend this unit. If you decide to order one and have any questions, a better way to contact them is "

Hope this helps
