This is the Avast Kalk K1 Stirrer, I used it about a year and a half and it works great. I replaced it with a DOS when my CA demand got too high because I couldn't resist all the SPS.
I'm also breaking down my big tank, so I'll cut you some great deals on coral while you are here if you are interested.
I'm at the highway 76 and I-15 intersection.
I paid $160, selling for $60. Here is the link:

This is what I'm selling, it will come clean with vinegar:
