IMO, all hobbyists should only get test kits that are accurate, if not, what is the point.
Hmmm... if the accuracy is still quite close to the best rated brand of test kits, its a viable option for the less fussy hobbyist/budget-constrained ones.
I see a good alternative to the very ex Salifert for the KH, PH & nitrate test kits.
Too bad I don't have a sample to verify against my salifert calcium & dkh testkits and Pinpoint PH monitor.
