Like the majority of you knows , taylot test kit and taylor reagents are extremely expensive here in Canada. So I'm searching an alternative to test Total Alkalinity. What is your opinion about aquarium KH test product ? Something like this Alkalinity Test Kit - Aquaforest. Here is the pdf manual : https://aquaforest.eu/wp-content/uploads/2017/10/AF-TestPro_Alkalinity_manual.pdf. It can perform 78 to 100 tests. It cost 18$ CAD
