I Have the queni koi 35 drum. Has anyone fitted the Amalgam submersible UVC, What fittings do you need and what size UVC will fit, pond is 5500gallons so looking at the 40w version. Anyone fitted one or any advice.
I still need to buy one yet so if you are a supplier send me the costs and any fitting instructions

5500 gallon, running through 2 x Aeriated bottom drains through 4 inch pipe to Drum filtration onto large Bio unit feeding to 2 inch pond returns, 1 return going through 15kw Heat pump, 1 going through Bakki shower dropping half back into Bio unit and returning to the pond. Heavily stocked.

I have a stainless profi, I bought one of the coastal koi uv's, have to say very good units. Can order from them with fitting for either drilling the drum if you have PVC drum or in my case i attached via a 4inch -> 1 1/2 inch rubber boot via one of the 4" outputs.

Found that the UV on the clean side helps keep bio film off the drum mesh.
