Test Kit reagents

[mrtian97]

Is it common that the test reagents went bad prior to the printed expiration date? I saw this with the Red Sea Magnesium, Red Sea Calcium and recently Red Sea Alkalinity test kit. Each time, the test results read lower than it should be (triple checked, including buying new Red Sea kit, which the new kit result is correct). And I see the bad testing only after 6 months from the first time I opened the reagents.

If this the common norm, could Red Sea consider smaller test kit, such as 40 instead of 75 tests.

Thanks

That' a good question.... I have jaye the red sea cal, and mag tests and I have had bad readings with the mag even after I spoke with the company and they sent me new reagents. I now use seachem and others to do my testing.

This is actually very common (from what I've experienced personally) with the alk and calc red sea kits. After about 3 of so months of them being opened, I'll usually get a lower reading compared to a newer refill. This is a constant (I wouldn't say issue) but dilemma that I've dealt with hence why I now only use red seas calcium kit.

My brand new NO3 Pro test kit arrived with liquid spilled all over inside, had to be coming from the "A" reagent bottle. Must not have been sealed well from the factory. Makes me wonder if quality is compromised.

Anyone knows if this is normal for the Red Sea calcium titrant? I received a replacement and looks more or less the same but I don’t recall seeing the white chunks before...expiration date is 1/2020. Thx

I have white chunks also in my Ca reagent, reading is ok so far
