Re: Charcoal filter question
Hi... Yes i don't mind filtering out the brighteners, im aiming for a total filter through. Can you tell me is it best to heat the soloution or strain it through cold.
I would also like to know the best way to check the PH value, would i be right in saying.... bubble the liquid for a short period & then cease bubbling then test with liquid (cold)??
Any advice on the above would be great!
