Quell, quell st, finest but too name a few.
Anyone know in relatively plain English what the difference is between them all?
One i believe is just a carbom filter but can anyone confirm?
Also total vs temporary hardness and TDS meters - used to use a drop test kit and tried a tds meter. Meter readings were miles out (lots higher) so im unsure which would be correct? Are there 2 drop kits around in the wild - one is temo and one total?
If Brita can’t answer the questions about their differing models, then I wouldn’t have much confidence in them.
Total hardness (AKA GH) is the calcium & magnesium (responsible for scaling) in the water.
Temporary hardness is the buffer/bicarbonate/alkalinity/KH, in the water. This is the most relevant value.
TDS (total dissolved solids) is everything in the water.
TDS reading will usually be higher than the other two alone. You could add total & temporary hardness together and it exceed TDS, so they are terms for different parameters and there is no predictable relationship between the three.
Please check out one of the other water threads.
Is there a digital meter for ‘hardness’ alone?

For greater accuracy, test using 20 ml water and (no of drops x 17.9) / 4 to get your total hardness and alkalinity in mg/l.

Not that I know of
