Hello All, Not to sound dumb here, but I have never tested for cal or alk before and want to start. That being said, what brand of test kits do any of you reccomend that are pretty simple to use??
For Alk & cal, Salifert kits, no question they are one of the best. Click on Dry Goods to the left. SWF.com has the best price around. And I've checked a lot of places.
