hanna

I used the tester a few times and, with proper care and calibration, it works great. However, I was given a hydrometer as a gift and have switched to using that so no longer need the digital tester. This also comes with about 25 salinity calibration solutions.

Hello All, I have a brand new unopened Hanna Magnesium Test Kit. I ordered about a week ago from BRS. I accidentally ordered two of the same kit. BRS has them listed for $64. I'll ship to your door for $50 or possible trade for other reef related items. Thanks!

Almost Brand New Just needs new reagent, then its good to go. I just switched to Salifert as it’s easier to use and more accurate $40 pickup $45 Shipped 19114

The weirdest thing has been going on while testing. So I have the hanna phosphorus ULR and the Phosphate readers. So I know they have a conversion chart for the phosphorus and for some reason I had a 200 plus ppb reading last night. So i was like no way something happened while testing. I said...

Does anyone know what calibration I should use for the phosphate checker Hl744-25? A picture of it or link will be great. Thank you.

Hi all! I have this Hanna Checker HI713 for Phosphate, the low range one. My issue here is that when i test, at the first reading after timer ends i have one reading, let’s say 0.26 ppm and as i always check twice, at the second reading i have always half or less from first reading. I perform...

Little story: Since my Hanna PO4 URL checker always turned on and appeared to work properly, I always assumed that, despite the glorious reviews, it probably wasn't that great. In fact, according the PO4 URL checker, both my display and my coral quarantine were always a random number between...

Anyone checked out or used this product yet? Hanna claims it tests like 9 parameters. quite a chunk of change at around 500 big ones. But if it does what it says and does it good. I may be interested. Seems very convenient and space saving...

I have an HI700 Hanna LR ammonia test kit, when I put the reagents in, the sample turns cloudy/milky (like a body fluid...). There's no discernible color like yellow. I've run the test 3 times, each time I get the blinking 3.00 (out of range result). To make sure I'm not crazy, I had my wife...

In the grind tonight. Wondering what others thoughts are on these Hanna checkers. Any lovers / haters?

So on one of my Facebook groups a guy mentioned he uses the API reagent in his Hanna nitrate HR checker. He was very vague and not helpful when I asked him follow up questions. Has anyone else done this with success? Getting 125 tests out of API for cheaper then 25 Hanna reagents seems like a...

Have three Hanna checkers, got them with a used tank set up and have duplicates. Thought I would give a good deal to you guys. $90 plus shipping. Would prefer not to part out, but if I get enough requests I will. Will also entertain trades for coral or other equipment. Hit me with what you’ve...

Hi guys I’m having a dilemma. I can’t figure out which ph reading to believe and it’s driving me crazy.. I have a Milwaukee ph monitor (mc120) and it reads 7.9-8 and I have the Hanna hand held color meter and that is giving me readings of 8.5 I want to keep it at Atleast 8.2-8.3 so I have some...

So I just got a hanna calcium checker and the instructions say I need to use distilled water. Is it ok to use RODI water? I looked around and I see that some people say it's fine while some people say it's not. Any thoughts on this?

I'm cycling a QT tank right now and I dose my tank with ammonia and fritz turbostart 900. I tested with salifert and my ammonia levels are 1.5, nitrite 0, and nitrate 0. I have a nitrate HR tester and I tested the QT tank and it came out to 19.4 nitrates. Which one do I trust? (I tested using...

Hello everyone! I was just curious on what everyone keeps their phosphates at in their reef tank?! I have a 15 G Nano tank with softies and LPS. My phosphates on my Hanna checker ULR is 0.06. Is this acceptable? Just looking for some opinions because I have seen mixed reviews online! Thanks in...
