So I just spent quite a bit on a 25 pack of 5-in-1 test strips. After having gotten home and using 2 already, I realized that the precision of the strips is sorely lacking, and that I could have gotten a 100 pack for a bit less than I paid for the 25 on Amazon. Of course, I had looked before I went to the store and while in the store, but couldn’t even find that product online then. Now, having taken a college chem course, I know that there are much cheaper and more accurate ways of testing levels via titration, but I never paid enough attention to know how to do that kind of thing on my own. Does anyone know how to do something like this or have any experience doing any sort of DIY testing? I know reefing is an expensive hobby, but it seems like test kits should be able to be mass produced easily and, as such, are a massive rip off. What’s more, unless I want to spend a few hundred up front for a system that would measure the levels for me, this is going to be something I have to keep spending money on. Any suggestions would be appreciated.
