Thread: Amalgam uv placement

Hi All.

Just in process of planning filter house pipe work on new pond build (2400 gallon, bottom drain to Nexus 220, skimmer to Cetus sieve returning over Bakki shower.

The problem I am having is where to put Amalgam UV.

Was originally going to put a t piece vertically with the side t leading to a 90 into the sieve. However, if I do that to fit the ball valve and associated pipe work pre sieve would need a depth of 1275mm below base of sieve (similar with nexus).

Every option I think of is no good.

Does anyone have similar setup with an answer to problem?

Thanks in advance for replies.

Somewhere between the pump and the pond after the Nexus would be the most ideal location.

I’ve got a similar set up and put my amalgam in the sieve, so the water flows around it before going over the weir. Works great, but guess would depend on how much flow is going through your skimmer.

Saw this photo and instinctively looked away from the light lol.

Assume that location is fully UV resistant?

I now know parts of my drum aren't!

Relative to above?

My son 3D prints some parts for me to use in my filters and pond. He's just got me to buy ASA 3D Printer Filament for some parts I need, the only type of UV stabilised material ATM, and more than twice the price of normal ABS, PLA etc. etc.

Well see - but not soon

Can I ask what modal UV that is ? I need to add more UV but cant stomach the cost of an EA one right now

Know what you mean about the light! The sieve had a lid on so not a problem normally. Believe the ultra sieve 3 are resistant.

It’s a fully submersible one.
