Did you just drop the denture tabs in the bottle? Anything thing else I should do etc, mines not working but I can still hear a pump so want to try this before replacing pumps etc.
I broke them up first, as long as they dissolve though it'll do its job. I also put them in with hot water, it may take a day or 2 to take effect. Mine was still working just not very well so not sure how well it will work but for a £1 pack of tablets its worth a shot.
