Love the new intro Marc. One tip on the Hanna Checker. If you face the "10 ML" label on the cuvette towards you when checking C1 and C2 you will get a more accurate reading. That way the eye is looking at the same spot of glass both times. This is by far my favorite of the Hanna Checkers. Super simple.
Iike I told you before I test twice a week with all Hanna Checkers and never been more happy on how easy they are and how accurate, I can’t ask for more of this test they are GREAT I 💯 recommended. Great idea on having a RO small faucet to rinse them , I’ll copy that to my new house laundry remodel
I’ve been using mine for 12 months it’s great and the calcium phos too currently they don’t have one for mag. The cons for me are reagents size is a bit small and the curvete fill line rubs off over time. I highly recommend them. I just got the ph tester seems good.
I really like the Hanna checker, all except the Calcium tester that is. A few tips possibly for you. Hanna told me that the meniscus of the water should be on the line in the tester. Fiddling around each time with the exact level was a pain, so I bought a Lab mincro pipettor that is dialable from 1-10ml from Amazon. It is just set the required amount, draw the fluid and put it in the vial. This, in theory, should give me the exact same volume every single time I measure the liquid. I ignore the 10 ml on the vial. The reading is thus 'consistently' inaccurate with each test. The pipettor is great for all the different tests, and also is great for measuring specific amounts of various other chemicals we often need to dose (for example I dose 0.7ml of iron each day). Another tip for consistent inaccuracy is to use the 10ml mark on the vial and always point it to the front. This way any refraction errors in the glass vial are constant between the calibration of C1 and the reading of C2. Another tip is that I only handle the vial with a glasses cleaner cloth and clean it only prior to the C1 calibration. The theory being that any smudges are also calibrated out. Cleaning before C2 could possibly add inaccuracies. But a great video as always.

Thank you for the helpful tips, I'm sure others will appreciate your suggestions too. I'll check out that dispenser tool, sounds very useful compared to the ones we usually get which are sold in bulk and may not be as precise as we'd hope.
love it. the phosphate hanna checker is great too - but I wish the reagent powder came in a vial with a scoop instead of the annoying packets. picked up the calcium one too... its a bit more of a process.
Jase Poag - I would agree, and I dont like that it requires fresh RO/DI water as part of the process... means I have to carry a bottle of water with me now too when servicing my clients aquariums - BUT , I do like the lack of titration/color change and the digital read out vs. matching to a chart.
melevsreef - look forward to it! if you have a voice with hanna, please pass along the feedback that the packets are annoying and a jar with scoop like everybody elses kit would be preferred LoL
Wow, I didn't know about that part of it. I guess I could dip into my ATO reservoir every time I need to test, but that really sounds like a pain. Oh well, I only test calcium once a week. Titration isn't so bad for that. I'm just glad the alk test is so easy. That gets done every other day.
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.
Great video, one thing to add. For consistency you should try to position the cuvette in the same position in the checker between step 1 and step 2. I make sure the 10 ml is forward all the time. There can we subtle differences in the glass that can make the colorimeter read differently. I love them, I wish they had one for all of my testing.
I have neve r used that tip and also my syringe has a tiny tip hanging from the stopper not like the one you have. I sometime get a ai rbubble around each side of the tip and I have to pull regent out like 3, 4 times for it not to be there. Wonder if this is throw off my reading because I just compared it to my red sea that I havnt used in a while and red sea is over 1.5 higher alk! It crazy. I dont even know if I need to dose or not! Isnt it weird how different syringes measure ml differently? ! ml should be 1 ml no matter what syringe you use. I just started making sure I put back the right 10 ml or 5 ml syringe back in each box corresponding to the kit I use of it will throw off the consistency!
I just wasted basically 59 bucks on a red sea alk tester, havnt tried calcium and magnesium yet but alk sucks! Color change is so hard to detect from the light blue to green and yellow if you went to far! to many steps and if you have bad eyes like me its very hard to read the ml lines on the small syringe...lol. Big digital readout is perfect! haha. To bad these cost so much as i would love to have one for everything tested! My hanna salinity tester is my best friend, especially when you do weekly water changes on 3 tanks!
When checking DKH in the effluent drip of a calcium reactor reefers are looking for 25 to 30 DKH , but the Hanna checker max reading is 20 DKH , I am assuming one would need to dilute the sample , so i was hoping you could touch base on this or add any recommendations to test effluent in calcium reactor.
There are tests kits that have you drop one drop at a time into a test tube. The number of drops you add before the color changes is the dKh, so in your example 25 dkf would mean a color change at 25 drops. API makes a cheap kit that does that. It only has 1dKh granularity, but when you are testing your CA RX effluent, that should be accurate enough.
You made it seem so easy. I am always like what do I do again . lol My alk was low and at 5.0. I had been dosing like crazy to bring it up . then all of a sudden. I lost a birdsnest . dang sensitive coral . what buffer do you add to raise your alk when its low?
Since it was pretty low yesterday, I mixed up four heaping spoons of Soda Ash in a cup of RODI water, and I poured that into the tank gradually over a period of hours - not all at once. I haven't tested yet today, but will. And I'm going to refill my reactor with more media.
I bought one with a spare regent, to my disappointment it reads low from both batches of regent. I doubled checked against my salifert and I also tested against natural sea water. And I tested my LFS water which my frags came in. I decided to calibrate the situation by putting more regent in to get my control. However I know that 6.9 reading is 7.7 , did a heap more tests to double check, on both batches. Little disappointed, but I’ll just look for 6.9. The calcium is dead on, but man it’s a process and , Hanna listen up ! Get rid of the sachets! Give me a scoop or anything but those bastard sachets ! It’s like your dealing coke flicking that packet !
ive never had good luck with these. my alk checker with new reagent kept saying my alk was at 7.7-8.3 so I would dose more alk. test again still reads low. this went on for almost two weeks. corals started to bleach and a RBTA started to die. went to my LFS and had them check my water.... my alk was really at 17. so because of hanna I almost nuked my tank.
Same thing would have happened to me if I didn't also own a Red Sea test kit. I checked my Alk with it after not trusting the Hanna Reagent. The Hanna was showing my Alk way low which I knew wasn't true based on how I am with my tank. Hanna was good about it and sent me some new reagent. I've been in this hobby just over seven years so not super long but long enough. I've never had a bad reading from my Red Sea Tests. I still love my Hanna checkers but when my reagent runs out I find myself using the Red Sea Tests and putting the Hanna's away for a while. I buy more eventually to double check the Red Sea. Still hasn't let me down. The Alk and Calc Red Sea tests are so much faster and they're accurate enough when comparing the results to the Hanna Checkers. Calcium is pretty much the same and alk is .5 higher with the Hanna consistently.

Wow Marc thats easier than the phosphate test kit will definitely invest in one
Because of your review I ordered one and it should be here later on today😁👏
Love my hanna checkers.
Use them nearly daily.
That's a lot. What requires you to check so frequently?
melevsreef..... New toy syndrome. And I am holiday's at the moment. :)
@@melevsreef
You did the test wrong..... There is something you did wrong that you probably don't know.
Yes!! We love ours too. I just got our newest version Hannah Checker for Copper testing. This should be a big help for QT procedured
I really like the Hanna checker. I use it about 2X/wk. along with the Ca. Checker. Reliable, easy & accurate
That is my favorite tester . Love the DKH Hanna
Great product Demo ! Showing the open battery compartment , 5000 test per battery ! Auto shut off , Cleaning , Thanks . I's gotta get me one !

Love my alk checker. Well worth the investment. Wish they made nitrate and mag.
I use these a few of these kits as I have partial colour blindness due to age and I find them to be great.
Definitely!
I love my Henna Alk test kit its the most easiest and accurate test kit for the most important parameter...

I'll be doing both of those as well.
Been toying with getting the calcium one for ages, but I've always heard it's no easier than titration, so I haven't bothered.

Hanna is the only way to go. I have every one they make. If only they had a nitrate tester.

Soda ash, aka baked Baking Soda. www.melevsreef.com/articles/diy-make-your-own-soda-ash-cheaply
Is there a specific period of time you will build up your alkalinity up again? Or wil you dose your alk from 6,5 up to 8 or 9 in a houre or so?

why does water goes way above the 10ml line on cuvette even i try to measure with 10ml different syringes?
You could ask the maker of the device.
So you don't put the blk part on syruge on 10ml

I'm pretty sure this is not faster than my ordinary Salifert testkit.
I know this is an old movie but i think you need to pull the sringe to the end and not to the 1ml line. This is what hanna said on thier video
Where's the second video of Tammy's reef
That video will roll out in 2-3 weeks. It's going to be a big editing job, and I'll be out of town for a while.
