Okay so Hanna's Digital Salinity Meter requires calibration right? Could Hanna produce a Checker that did not require the purchase of calibration solutions? For example if a Salt Mix Pack says "Mix 1g of salt to 1 liter of water for 35ppt" Bearing in mind Hanna Calibration solution is 35ppt, you...

I have been using a 10ml syringe to accurately fill my cuvette for awhile with no problem. I recently bought new cuvettes from saltwateraquarium.com they came and they weren't the same as the old ones and fill past the 10ml line. I thought maybe I got some bad cuvettes so I ordered more from...

I'm a bit overwhelmed by the number of Hanna Checker for phosphate. I've opened a poll to see which one you guys use. Could someone correct me if my understanding of these three checkers is wrong? And maybe suggest which one I should get? The HI774 sounds like the best choice for someone who...

I was trying to make a drying rack for my Hanna Checker vials and was having a hard time finding the thread size for them. I tried calling Hanna and spoke to their tech department and they didn't know what the thread size was either. Any help would be much appreciated and thank you for your time!

Hey everyone. I just received my Hanna checker and honestly, I’ve confused myself on what phosphate level i should be shooting for. I keep reading that I need to be around .02. Today I tested with a .28 and started panicking. But I have no algae problems and my corals looks fine. If this level...

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...
