>>Anyone know where to get a conductivity meter at a decent price also what is a decent price???<< Hanna Instruments has a model on sale until the end of the year for $15. Many fish folks use it and have good reports on it. Their web site is: http://www.hannainst.com/products/promo/usa/usaprmo.htm#pH BTW, There was a long thread on the killies list last month on using meters and water chemistry in general. One of the main contrubutors is writing an article for JAKA that promises to be required reading for anyone keeping fish. I'll try to remember to send a notice to the Apisto list when it's finally in print so your clubs can ask for reprints.
