hanna

So, here is my dilemma. I have been testing my tank religiously with the Hanna DKH Checker for the last 2 years. I do not currently use a Salifert or any other brand DKH checker to validate the test results of the Hanna checker. I have prepared three 5 gallon buckets of salt water for a 15...

SOLD Price dropped to $175 We've switch our system over to Trident test and since then the Hanna is no longer being used. Works perfectly. You will need to order a few of the reagents since they are mostly gone although it still has the Nitrates reagents. Asking $215 shipped

I purchased a hanna nitrate checker and phosphate ulr checker. I wanted this because I'm currently fighting amphidinium dinos. My tank is roughly 4 months old, no Coral, 3 total fish with a bit of clean up crew. Nothing but rock and sand. No scrubbers or gfos to remove anything, no fuge. Even...

So I have a 32 Gal Fluval Flex that has been running for about 9 months now. Recently, I had a couple Zoas and a GSP that have been closed up for a few days so I decided to test my water. The results were: Ammonia: 0.0 Nitrite: 0.0 Nitrate 0.0 (checked twice w Hanna checker) Phosphate:0.37...

Hi all, Does anyone know what it means when the ULR Phosphate checker blinks 0.00? I’ve had a zero reading before, but never blinking.

I've heard about the problem of Hanna's Magnesium colorimeter reading high and recently learned that you can fill out a form on the Hanna website to get them to send out a new Reagent to correct the issue. But has anyone not had to do this and is getting similar results to other tests they do? I...

There are several threads accumulating on the forums of people having issues w/new marine magnesium checker HI783. There are also some similar reports on the AskBRS facebook page--results several hundred points higher. I wanted to start a thread here in Hanna Instruments sub-forum to give Hanna...

Hello , I need help to determine if my levels are good. I’m keeping mostly LPS and softies. Thank you

I picked up one of the new Hanna HI783 Magnesium checkers when they dropped last week, and after one or two mulligans I got it working pretty well. A little more complex than the basic hanna tests (requires 2 reagents) but nothing too bad, especially vs the other titration mag methods. The...

I was wondering if there was any Salinity testing equipment that actively reads Salinity in real-time, I use the Hanna Salinity Checker which I really enjoy but sometimes I get the feeling that it's not as accurate as a Refractometer.

Back when I was testing more regularly I bought a Taylor SpeedStir portable magnetic stirrer for use with my Red Sea titration tests. Even with a smaller 15mm stir bar I had to make sure the cuvette was absolutely centered or the bar would just bounce off of the sides and get stuck. It was a bit...

Ok, so I know this is a highly debated topic, and ultimately most people recommend both ultra low range checkers, but my question is for a newly set up tank where phosphate could easily be above the maximum range of the ultra low range checkers (0.9ppm i believe). Would it be better to get the...

Maybe I was the only one who was left in the dark, but some German sites show: HI783 Hanna Marine Magnesium Checker HI784 Hanna Marine Ammonia Checker I'm so glad I won't have to do any more titration tests. Anyone else is very keen to try out the new magnesium checker? The Magnesium one is...

Hi. I wonder if there is a way to determine the clarity of Hanna Checker Cuvettes, so that one can determine if it is time to change them. I imagine that the checker itself should be able to give you a value for the cuvette with RO water that you can use to determine its "clarity". No...

Just getting back in so not sure if to spend on the Hanna checkers for calc alk mag and phos or purchase something else like red sea or api or any other out there now
