I’m getting back into the hobby after several years out. I can’t seem to find the refills for these old test kits. Are they still in business? Anybody know where to find them? The photo is the Ph refill (expired 2005). Thanks.
I switched from Nyos test kit to the Hanna testers. If you cannot find refills you might try one or get one you do not have a test kit for to try them. I have the Alkalinity, Nitrate high range and calcium testers. At the time I switched the refills for Nyos were about 1/2 the price of the Hanna tester. I have a Milwakee phosphate tester and I do like it but got it before the Hanna testers were out.
I did, thanks. For those, it looks like you add a liquid media to a tube, swirl, etc. The ones in the photo i posted, you add a dry media, shake and compare to the color scheme next to the sample. It was really easy and worked great. It doesn't look like its around anymore.
