Hi Carl,

Not easy, as I can't source a good test kit up here in Canada, nor many of the suggested chemicals.
I very nearly couldn't find muriatic acid! Luckily, Rona carries it! (No-one else does!).

I can't monitor cyanuric acid levels, nor borate.
I only have test strips.

We also have very hard water here in Calgary, so not using 'Secure' (which I think helps address the damage hard water would otherwise do) is not yet a wise thing as far as I can see.

How does the BBB system address limiting the damage of very, very hard water..?
