Looking for a 2 or 6 month supply unopened. If you have some let me know.

Hi, I've seen a lot of people selling Hanna checkers recently, along with a lot of people having issues with contradictory/fluctuating readings. My question is are they actually worth the money or has the initial excitement about multicoloured eggs worn off?

this one has me baffled! I have and Alkatronic and have been trying to mix reagent. it's a simple 4 to 1 mixture. I also have several bottles of Premix reagent from Coralvue. Also got concentrated reagent from Coralvue for the Alkatronic. Using CoralVue ready to use reagent in my Alkatronic...

Has anyone used these reagents from www.abcreagents.com for their trident? Supposedly they work just like the Neptune reagents but obviously they are much cheaper. If people have any experience with these, please comment. If they work well, this will definitely be a game changer!

There is a way to hinder the Hanna alk to show lesser and lesser dKH (or ppm for that matter) with age of open reagent bottle. I had the same story as many have reported here - my reading decrease from a new open bottle with time. Double check with another method show that there was not a real...

Hello I am purchasing a Xepta AutoBalance from Spain and am wondering does anyone know if the “reagent” used is just 0.1 N Hydrochloric acid or equivalent? It’s going to be difficult/expensive to get my hands on the Xepta brand reagent so I’m wondering what my options are for DIY reagent for...
