My old chemical regime used a liquid called Spa Life 'Secure' (replaced with Aqua 'Cop-Out') on a weekly basis.
The bottle says, "For the prevention of metal stains and scale formation".
How does the TFP / BBB system address similar stain / scale prevention?
Or is it the case that, if the water is balanced as specified in aforementioned systems, then such staining / scaling simply won't occur..?
I'm pretty sure that you guys will have an excellent reason negating the need for this ancillary substance.
My curiosity is keen to hear what it is.
With the gaining of such knowledge, my mind grows ever more aligned to the Ways of the TFP...
