I liked that 1 too until the eyeball went wacky....ask my wife how that went.... ha. Well if you ever are in the market again...cant get ANY better. Hard to spend the $ on it but I'll never go back. I would at least think about looking at avast's ato sensor. Alot like the Spectrapure one, there's no electronics to fail. Works off of pressure vacuum instead. Flawless design. Avast is probably my favorite small aquatics company because there products are pretty much bulletproof and well designed. Not too bad a price either.
