Likely you will end up concluding as I have that the brand known as "Cheap" is preferred. @ about $15 from e-bay. Don't see any provisions to change the battery on it from what I can see either. Hopefully as seldom as I use it, the life of it will exceed a year at least.
The problem I seem to have with this issue is that the ingreedients of those things which you would use to raise the TDS level are listed vaguely at best on those products. I am not one of the fortunate ones who can spend whatever they like on my hobby. I (think) I can see that those ingreedients are exactly the same as MGSO4
and CaSO4. If these cost $4 per pound, then why would I buy "Equalibrium" for $6
per OZ ? But since Equalibrium says..."contains Calcium salts" I really don't know they are the same. So I hessitate to use them instead of Equalibrium.
I simply can't use a $6 per OZ product every time I change water. So the TDS meter
serves what purpose ? Believe me that if I was to buy shrimp that cost $49 for five of them I would also buy Equalibrium. But as long as I just keep RCS...
I looked it up and the store on e-bay which I bought mine from @ $8.95/free shipping was "podvillage"...
The shortest distance between any two points is a straight line...in the opposite direction...
