Liner algae to point of rock

[lukes pond]

Guys my liner is prob 15 years old. As a consequence the inside of the liner has gone almost like white rock/

I'm trying to renevoate my pond area but didn't put in a new liner.

Is there a solution for this guys?

Cheers,

If by white rock you mean the residue left over after water evaporates called limescale.....Vinegar or lemon juice will usually remove it if that is actually the issue with your liner.

I was going to say the same thing - sounds like mineral deposits. If it really bothers you, you could remove it. Or just leave it - it won't hurt anything .

@lukes pond
I just used an old liner I had for a new frog pond and it had that on it too. Not worried about it as it will soon be covered w/green carpet algae which is a good thing!
