Absolutely I always verify test kits with one from a different brand.Trust but verify!
I learned a very hard lesson not to 100% trust hanna alk checker. Apparently had a bottle of "bad" reagent and dosing tank thinking alk was low when SKY HIGH and believe that is why I lost ALOT of coral and fast. Just this past weekend I first "calibrated" my checker using "Marine Alkalinity Checker HC Calibration Check Set" then tested using reagent purchased in August and tested using reagent purchased in Dec. readings were VERY different, 6.5 using older bottle, 9.6 using newer bottle. I contacted Hanna and was told the reagent is good for one year as long as stored properly (cool dry place) which it is. I ordered another reagent should be here any day very curious reading I'll get.
So far 82.9% out of 41 people trust their Hanna alk checker
YesIs that good or bad?
Well it seems the majority trust their Hanna alk checkers as for actual accuracy your guess is a good as mine lolIs that good or bad?
Do you store it in the fridge?I trust mine as long as the reagents are fresh. I use a trident for daily testing so I only use the Hanna every month or so. I found after the reagent has been open the value drops drastically. For example prior to sending off an ICP I did a full batch of manual testing. Trident 8.4 Hanna 4.7 verified with a Red Sea and icp test that the trident was in the right range. Opened a fresh reagent bottle, and the test was much more accurate
Funny enough I recently saw a thread about that in the BRS Facebook group. I am going to start doing that with the next bottle I get. It seems like the reagent losing potency is a common issue and fairly well resolved by refrigeratingDo you store it in the fridge?
Yes, Lasse had a thread here a while ago about putting in the fridge.Funny enough I recently saw a thread about that in the BRS Facebook group.
