We use the Hi713 in most cases as it is easier to use and read over the phosphorus which requires additional calculation to convert to phosphate.

It really is easy By Aaron on 7/18/2016Aaron wouldn't recommend this product to a friendI was hesitant to grab this because of a few reviews that stated it was difficult to get all of the reagent in the curvet but if you flick the packet a couple of times to get the reagent down to the bottom corner, cut the packet like instructed, and fold/roll one side to create a half funnel, it just couldn't be any easier.
Good By Niko on 4/3/2016Niko would recommend this product to a friendI like it!
Awesome By crocogator106 on 3/30/2016crocogator106 would recommend this product to a friendGreat piece of equipment. Exact digital readout-no trying to match colors and guessing. Very easy to use.
Hanna check ultra low By Nate on 3/20/2016Nate would recommend this product to a friendGetting accurate readings and working great. you need to make sure your glass vials are cleaned and use all the reagent. Then it will work like a charm.
Get The Phophous Test By Sunghoon on 3/14/2016Sunghoon wouldn't recommend this product to a friendThis one still doesn't read low enough. I should have bought the phosphorus test and done the conversion. Algae is still causing levels to be to low.
decent product deficient marketing approach By MaLi on 2/20/2016MaLi would recommend this product to a friendSeems to work well, but I was amazed by the fact that with the meter there are only eight (8) reagent tests. Strange and cheap given that a pack of 25 is only $9. In my opinion really bad marketing strategy. A bit of a ripoff. I will not recommend to others though I believe is a decent quality product. Hopefully marketing will learn something.
Easy to use, worth the price! By Jwill275 on 1/18/2016Jwill275 would recommend this product to a friendEasy to use, open reagent before pressing button 2nd time, gives you more time to empty reagent and mix. I always seem to have a small amount of residue in bottle but I'm very happy with results so far
Not for the Dain Bramaged By HANNAbanana on 9/21/2015HANNAbanana would recommend this product to a friendMine works great, consistently, and flawlessly. Just be careful, slow, and I have found that it helps to roll the test vial horizontally to help get rid of microbubbles before testing, if not, can cause the problems that most complain about. Also, cut the reagent packet on 2 sides.
poor function design By northerner on 9/3/2015northerner wouldn't recommend this product to a friendVery difficult device to use . Preparing the meter for sample testing is a crap shoot ( meter responds different every time ) , resulting in many wasted samples and time. The powder packets are a little difficult to use and the results are probably accurate if you ever get the meter set-up. Not user friendly.
Great results, poor design on regent By Zane on 8/19/2015Zane would recommend this product to a friendThe test works great and gives you very accurate results. I would've given it 5 stars if it was not for the absolute poor design on the regent. As many others have stated getting the regent into the vial without losing or missing some is almost impossible. The regent should come in something similar to the salt packets at Wendy's or other fast food chains. That way it would be rip the top, then pour into the vial with no chance of losing some of the regent. It would take a simple, but easy change to make this product perfect and more accurate since all of the regent would make it's way to the vial.
Good test By Scott on 4/16/2015Scott would recommend this product to a friendI think this is a great option for measuring the low phosphate levels typically found in a reef tank. Make sure you read the direction 'carefully'. I did not and ended up wasting 3 tests of the 6 that come with the tester. I also think they need to get rid of the packets of reagent. Those things are a pita. Hard to get all of the powder out and hard to make sure what you can get out ends up in the jar. That being said, I would still buy it again today and give it a 4 star rating.
Very accurate By Jason on 11/30/2014Jason would recommend this product to a friendI just received mine in the mail and it works great! It's very easy to use and best of all you can read the results. I have never been able to tell what my phosphate levels were using shades of blue test kits.
