Calcium reactor id

[JSpen]

Ok so found this reef octopus calcium reactor at my lfs store for $99. I’m trying to figure out the model so I can find the manual. Let me know if it’s a good model or if I should pass. Thanks guys and gals!

I think it would help to get the reactor size. 4", 5"?.that would help with a Google search trying to figure out out.
But seems like a good deal..reef octopus is a well known name
