Don't ask me about koi ponds/pools - we all know what I did with our koi pond/quagmire 
Either way Dave, it's a case of "Eish, we hef a prrob-lem"

I was thinking the same thing, but I'm certainly no expert.Yes. Silicone will not help as it is not good at filling gaps. A buddy of mine tried it with threaded water pipe and it didn't work fot that either.
I wouldn't even make the gap bigger. First use a clean wire brush to remove any surface grime and loose stuff, then apply putty as previously mentioned.
Good luck!!![]()
That's probably the smartest thing to do - ask somebody who should know.Silli I think I would have to make the crack a bit bigger as in some places it is so narrow that I don't think the putty will actually really fill the crack and I don't want it to be a huge lump on the side as I would like to use the other filler that is white to cover it up after the putty has dried. I am also going to have a word with the pool guys here as the one guy at work mentioned they actually have some type of stuff to do this and it is white. It is that stuff they put between the chipped tiles once they have them all done
