Review on 🐠 Enhance Aquarium Health with Seachem MultiTest Iron Test Kit by William Rothstein

Test kit works as expected but difficult to get accurate readings. Color differences at low levels are pretty hard to see (and low levels are what most people are likely to have, i.e. those using low-tech reservoirs and dosages). Testing for chelates and non-chelates at the same time is good, but the idea of reading one after a few minutes and one after 45 is confusing. Maybe it's all just the chemistry, but that's a question. I would rate it lower if they didn't add a calibration sample, which helps. It would be more helpful if they had a chelated and a non-chelated sample.
