Hi

Can anyone please tell me some alternatives to the really expensive chemicals sold by the hot tub chemicals.

I'd like to use Soda Crystals (Sodium Bicarbonate) as an alternative to Total Alkalinity increaser. From what I've read here, I think that's OK.

Is there an alternative to the Anti Foam on sale?

What do people use to clean their filters which is not the oh so expensive Filter Cleaner on offer?

And for anti-scale?

Thanks for your help
