Tips: Just buy the 774 and be done--no "progression" needed. I bought the 713 because of the "first year reefer" thing and the inaccurate statement of the max of 0.09 ppm. It's max is actually 0.9 ppm, she misspoke. Now I want the 774. The "pro tip" here is that the 774 tests up to 0.9 ppm and you don't want your phosphates ever anywhere near that high in a reef tank. Most people target somewhere around 0.03-0.1 ppm. The 736 is technically more precise, but the units are non-standard and require conversion or working in parts per BILLION and apparently it has timer issues causing it to shut off too fast. More tips: makes sure to immediately rinse your vials w/RODI water when done, twice. Then store the vials full of RODI water when not in use. Always wipe the vials clean with a microfiber cloth before testing to remove water, dust and fingerprints. Two vials are included w/each checker, but use the same one every time; you'll get more consistent results following these tips.
Plain and simple..Hanna checkers are just that easy to use... Makes my testing experience more hassle free.. From the monitor probes and Hanna. Can’t go wrong....Great know how too videos.
Hannah makes the best checkers hands down. But My biggest complaint is the packets being impossible to get all the powder out. They could either give you liquid reagent or a big bottle of powder with the same amount and a scoop
Question: I have a magnetic stirrer, instead of shaking for two mins can I use the stirrer and finally... do I have to take out the stirrer before putting it in the checker?
Someone kindly inform Hannah to increase the checker device auto-shutoff time from 2 to at least 3 minutes. How can you have a checker device auto-shutoff time of 2 minutes and a reagent shake/mix time requirement of 2 minutes???
The phosphorus checker reads in PPB instead of PPM. In other words, the resolution of the phosphorus checker is much more granular than the Phosphate checkers. This level of resolution really isn't necessary for probably 95%+ of reefers.
yea but for a 10g softie tank... I doubt I need to let phosphorus rise to 20 PPB. I aim for 10 or so. I could see if you have a large tank packed with corals. thoughts/feedback please and thanks? ps. I am currently tuning (cutting back lighting) on my 2.5g CPR hang on back fuge I bought from you guys. it's eating up all nutrients, showing dead 0 for everything. dosing neonitro/neophos daily 2ml/0.5ml and still 0's. plan on upping the dosing this week also.
Awesome info topic. I made the exact same progression from 713 LR to 774 ULR checker..as I kept getting 0.00 reading with my 713 LR checker. A couple questions: (maybe others are wondering too(?): -Is it true that the 713 LR Phosphate checker is not actually “certified” for Marine use? (Or if they all work for Marine use..Does that mean the “Marine” labels or certifications for the 774 and 736 are purely marketing based then?) -Are there other difference between ULR Phosphate and ULR Phosphorus checkers besides the built-in conversion factors? Ie: After factoring Ppb to Ppm, Are there different accuracy and resolutions between those two ULR checkers?
You guys should include the DIY hang on back refugium with aqua clear 70 overflows or any. I built mine for nano tanks and it works amazing and save money and one that fits actually
@@tomg5405 ive retested up to 3 times over and over from the same water sample " not gonna waste more reagents then that. They all came exactly the same. The problem with alot of people is that they dont clean the glass.
@@marcelrodriguez2067 I clean my glass very well.why waiste reagent you should take two bottles,one with water wihout reagent and one with so your sure tonuse them same prob and you can test multiple times without waiting.but maybe my hanna has a defect ,but they keep saying it works whennhe doesn.t
If you're trying to maintain 0.03 ppm phosphate with as little swing as possible, the Phosphorus PPB checker (then converting to phosphate) is going to be your best bet.
Really, the reading disappears after 2 minutes? lol Anyone stop to think that Hanna programs it to do that. I mean, I have a children's thermometer to check my kids temp that stores the last reading until it's used again. I can literally use it once a year and still know what was the last reading of her temp. I was thinking about getting these but kinda skeptical now. Now, i just need to find out how much the consumable is to make a decision.
I see the packets have a shelf life. How long typically is the shelf like of the individual packets - and does the shelf life of the packets vary depending on what type of test it is? (Phosphate, calcium, PH etc...)
The shelf life does depend on the type of reagent being used (some are liquid and some are a powder). Usually it's at least a year out. Reagents for the phosphate checkers are usually right around $10 for 25 packets, so about $0.40 per test.
LOL did hear what she said with glee? You have 2 minutes to read it or we erase it and you have to buy more reagent to check it again to see the reading that could have easily been stored in non volitile ram like 99.999 percent of devices out there.
I just want to get in the ballpark of where I need to be it makes no sense to make all of these type of checkers for checking the same thing it's total BS
Hanna kh checker is great, but the phosphat checker are a pitty.send it twice already back for fix, every time they say all is OK. Today I test my water prio to water changing, it showed 0,15, then after the water change 0,23 wich is impossible. Then I decided to use two bottles for the test one with the tank water, one with the tank water + reagent, I run the test 5 times with the same bottles, normally I should get close results but not each time I get different results from 0,14 to 0,04!! That is a big margin for error. I encourage you to do the test guys. It is not because a number is written on it that it is accurate. I not more trust Hanna, or my product have a problem and their customer service is incompetent or the product is bad as they say that it works perfectly. Believe me I did the test in the right way.
Have you checked Phosphate of your source water used for making saltwater? Also, you could purchase a reference solution to check the accuracy of your checker. (Hint: I always use two vials when testing with Hanna checkers. You can’t then have C1 and C2 ready to go instead of having to add reagent to same vial after C1)
@@Val_Halla777 hello yes I have check my osmosis water no phosphat. And if I test 5 time the same vials and it give me 5 times different results, the checker have a problem..

@2:02 Hanna ULR range upper testing limit is 0.9 and not 0.09 like incorrectly said in the video. In case anyone needs this info.
Was going to say same could sworn i seen mine lot higher then .09 when started out
Correct - www.hannainstruments.co.uk/hi-774-marine-phosphate-ulr-checker-hc-colorimeter.html
0-0.09 would be a pretty narrow range too.
the secret guy in gloves in the background did it :)
Yeah I noticed the same. Big difference

Thank you BRS as I was confused on which was which and why you would need each.

2:09. What does the Phosphorus ULR do differently? How is it for advanced reefers? Does it measure something differently? Range?

@@BRStv lol is that why it says 200 error since brand new p o c tubes to small spill regents nearly every time it makes me so angry lol
So i bought the phosphate HR checker can i still use it? Or do i need to go with the other three.
Some very good tips for accurate results. Hanna checker is my go to source
I’m waiting for the 2nd gen that will come with beeping noise when the timer is over

What happens if your trying maintain 0.03 ppm which is best because tolerance is 0.04 it's very confusing
If you're trying to maintain 0.03 ppm phosphate with as little swing as possible, the Phosphorus PPB checker (then converting to phosphate) is going to be your best bet.
Can't we use all 3 reagents in just one of these?
Each of these checkers utilizes a specific reagent. You'll want to pick up the right one for the checker you have.
@@BRStv Ok thank you....i was just wondering if all 3 checkers were the same with the exception of the different reagents, but I guess they're not :-(
Great but it would be more clear if you stated the model# instead of low range checker. I’m still confused which one to get. Sorry not being rude

Yeah that guy is so irritating I'm telling you
#9 use your cellphone camera to record the video of the checker because you know you will forget to look at the checker again after 1 minute.
LOL did hear what she said with glee?

ULR Range 0.00 to 0.90 ppm
yep 0.90 not 0.09 @2:02

Urghh i want to know about the high range
wait what the heck is phosphate and why should I care?
The answer is neither. Both of them aren't accurate enough to give you any results worth of knowing. The margin of error is too great to be useful
