   I'm looking to buy an inexpensive TDS meter as I need to start mixing my own water. If anyone has one that will be attending the tank tour Sunday that would like to sell it please let me know. Thanks

   Usually when you get an RODI unit you can throw one in for just a few bucks. I like the dual inline units. They're a little bit more than the basic TDS meters, but you can put them in to take measurements at different parts of the filtration process to see how efficiently all the filters are working.
