For a thorough "How to" you really should have described that using the extended attachment for the syringe and aligning to the bottom of the plunger, no matter where the reagent ends up in the tube, to the 1.0 line is crucial. I only mention it because thats where I messed up when I first used the checker. But I do appreciate these videos. Great job.

Just be careful to buy the right one! BRS sells 2 Hanna Alkalinity checkers, one gives dKh, and one gives ppm, where you have to do an (admittedly easy) math conversion. I was so excited to get the checker that I didn't notice, and ordered the wrong one. Still love it, just wish I would have gotten the dKh one.

My favorite test because Hanna makes it so easy. Love my Hanna checkers!

Could you guys do a video on proper acclimation for us new to the hobby? Things like how to inspect the fish/coral when it arrives, doing a proper drip (can show off your accudrip or other gadgets), freshwater dip, and what to watch for when your new pet is in the tank so you know they're doing okay.

Thanks for all the helpful videos!

A few of my personal tips for consistent accurate readings.

I bought a digital pipette from Amazon that lets me dial from 1ml to 10ml. I think this is the best way to get not only accuracy but consistency on your Hanna and other tests. This way even if you're not on the exact 10ml line you will always be consistently off it so the readings should be more consistent day to day.

I also clean the vial prior to usage with a glasses cloth and handle it only with the cloth. I dont clean it again between C1 and C2 since any dirt that was there originally will have been taken into account on the C1 reading and could affect the C2 reading if it has now been cleaned off.

I also make sure that the 10ml on the vial is always at the front to once again keep consistency in the refraction of the internal light and any residual dirt on the vial.

Maybe a bit of overkill but I get very consistent readings and its easy when you have a specific system.

Muito bom! Rápido pratico! Essa coisa de ficar olhando cores é coisa do passado.

The water in the cuvette should be added until the bottom of the little bubble(meniscus) is at the line. Not the top of the water. Confirmed with Hanna.

A few years ago they had a nasty issue. Ive heard it's corrected. I hope so cause I loved using it, but have been hesitant.

[LucidComposureUk]

Bought mine months ago. Wish I had years ago.

The funny thing about this, my two refill kits arrived at the door that I ordered Monday when I got notified about this video. Is BRS watching me?!? Lol

[crowndroyal]

Od like to see how one tests for GH in a freshwater aquarium with the checkers.

Is there an even quicker digital alkalinity checker or probe that doesn't require reagents? You know, kind of like a ph digital meter or the Milwakee salinity checker. Something I can just dip in the water or put a few drops of tank water in it, push a button and get an instant result without the use of chemicals.

How about showing the most important step, filling the syringe.

[johnwilliams]

Is the second glass cuvett just a spare

[fishguru-]

Any need to 0 it with RODI after several uses?

[haithamkittana]

Dear BRS

Does it required regular calibration?
If yes, how often?

Thanks

[brandonreidy]

Lots of questions here! Can you explain why sometimes the checker takes longer to go from ON to C1 or C1 to C2 or C2 to Reading? Sometimes it takes what seems like milliseconds, sometimes 30 seconds? I am very deligent with making sure the glass is clean and also mixed well. Oh yea whats that nasty stuff that floats around? New bottle, old bottle, kept upright, kept on side, plastic removed, not removed, ive heard all those rumors. For me it seems to always show up! Does it change our readings? If we let it float to the bottom will it change the readings? Does it make our test solution more concentrated, less? Does it mean we shouldnt use the solution?

I have a question about this checkers accuracy.  when I tested with my hanna all dkh checker I get a reading of 6.2.  but when I check with my salifert kit I get a reading of 7.3.  which one is correct?!  how is it possible to be so far off?  I tested multiple times to see if there was any variations and there were none.  I don't know which one to believe!  Help me BRStv... you're our only hope.

[chowhuiming]

Hi, BRS! Do you attempt to remove the air and bubbles inside the syringe after filling up the syringe with water?

[jluusaltwateraquarium]
