Butler sink for a wildlife pond?

[Georgie]

I'm thinking of making a raised wildlife pond (I've read up on how to do it) and I've just seen on Freegle that someone is offering an antique butler sink.  This sounds like a runner to me, what do you think?  And if I'm lucky enough to be offered it, what would you recommend to seal the plug hole/overflow.  Thanks.

if t'was me i'd use silicone /

[Georgie]

Right thanks.  Can you expand a bit on that, please.  Do I fill in the holes with some kind of cement and then use the silicone to seal or just use silicone?

we used aquarium glue sealant on ours georgie,the stuff you would use if you were to repair a fish tank

apply a thin smear of silicone sealant (fish-tank grade) to the plug, the weight of the water will ensure a water-tight seal. leave the over-flow open, to allow for overflowing when (if) we get a down-pour..

Thanks both.  Still no news on whether I've got it.

Want to ask (after I've googled, looked at pix, still can't find the answer ) what's the diff between a 'butler's sink' and a 'belfast sink', please?

PS...my sink, whichever it was & which I dug up as a 'treasure' in my garden x years ago, I tried sealing with silicone, as per grotbag's suggestion - it wasn't 100% successful & so I planted it out with rockery stuff..

Regardless of where it was made it is a butler sink. Belfast butler sinks have overflows other butler's often don't, others are often shallower too.
This article explains it better if you're interested.

Someone else got it.   

Back to the drawing board.
