Can someone help me I'D this UV sterlizer?

It's big but I want to see if it's enough to run a 300 gallon system. Also need to know where to buy the bulb.

It looks just like one that I had longgggggg ago on my old 300. Don't quote me on this but I think it's an old Coralife brand (maybe Turbo Twist)??

If my memory serves me correct, it's the contact time that the water has with the UV light that determines what size aquarium it's good for, to an extent of course. For example, when I downsized to a 100 gallon I just increased the flow rate through the UV to compensate.

I don't think that you need to figure out the exact brand, just find a matching bulb for it. The Coralife UV bulbs look like that one in the pic. Good luck!

Hmm the biggest turbo twist is 12x but doesn't look like the one I have at all
