    Hanna vs Red Sea Nitrite Testing

    Hi all, nearing the end of the cycle on a new tank. I have a Hanna Nitrite ULR tester that to-date won't give a reading as every test reports '200' (out of 0-200 ppb range). My Red Sea Nitrite tests are coming in between 0.5 and 1 ppt. I believe I should trust the Hanna (non)reading, but that's...

    Hanna Checker(s) Issues

    What? Every 10ml syringe I have, will fill about 1/8th" to 3/16" above the cuvette line (depending on how the water curves up in the cuvette) which is supposed to be 10ml. I've used 4 different syringes. Frankly, google searching "Hanna 10ml line not really 10ml" lead me to several pages of...

    Shelf life on API test kits?

    Does anyone know the shelf life on test kits? I did a test yesterday with an API and it turned blue as soon as I added the second reagent. I measured about a 2.0. I checked again tonight and the same result. I pulled out my Hanna checker and received a 0.00. I’d love to go with the Hanna...

    Another CA test gone bad

    I've read about others experiencing this but didn't give it much thought as I go through my tests well before their expiration date. My "old" -- less than 1 yr -- was off by 170 ppm. It was giving me a reading of 400 when I was really closer to 570. That got me to thinking, how many have...
