**Be Aware** Not Suitable For Reef Aquarium Testing! By Julio on 10/16/2016

Not sure why Hanna doesn't just Discontinue this product even though they know it's more suited for "Fresh" water than marine usage. I've owned this for 6 months and never had the digits read above 0.00 ppm! Had the signs apparently of having phosphates with algae growing constantly on my glass! Went and purchased RedSea's Phosphate test kit and Salifert's test kit just to make sure and too my surprise not only I had phosphates present in my reef tank but that the results showed RedSea 0.8 ppm Salifert 0.07 but yet my Hanba HI-713 can not detect these units! I emediatly called Hanna Headquarters in Smithfield Rhode Island and to my surprise, they told me that the HI-736 ULR which is the "Ultra Low Reading" test kit would be more suitable for me, which really indicates that thier aware of this problem! IMO, maybe they just never made an attempt to recall this model of kit in in order to save tons of money they just went ahead and slapped on the "Fresh & Marine " label and kept it as is but clearly if you don't see a "Fish" label in front of your handheld with the "Marine" label as well than it's not suitable for Marine! Unfortunately this problem is not going away! Reefers Be Advised, purchase the ULR instead!

Hanna Phosphate Low Range Colorimeter works well . Fast and accurate
Great.. packaging needs improvement. By Yus on 9/26/2016

The product it's great and easy to use. Take away from having to match colors. However, the packages the reagent comes in need to be replaced with a scoop method because it's hard to get all the power out of the packages.
Unsure of accuracy By Mark on 9/3/2016

Iva had this a couple weeks now and have yet to get a reading above 0.00 after 4 tests. I run hc gfo but should still have some phosphates right?
Really only 6 tests By Jaimeadams on 7/15/2016

I am disappointed with the fact that it only comes with enough regent for 6 tests. Sure the digital read out is awesome and very helpful, but I really feel that for the price I should be able to test more than 6 times before having to give them more of my money

I hate trying to match colors on tests (ok, I'm also slightly red-green colorblind so that doesn't help!) and this makes it so much easier. Doesn't come with very many test packets so if you'll be doing a lot of testing you'll want refills but they're pretty inexpensive.
Dies right after warranty By SD Reefer on 4/6/2016

Problems with the light sensor the minute the 6 month warranty was up. Randomly worked and then completely dead. Tech support offered up $95/hour service or they said I'm welcome to order a another from them. Don't think so. The results I was able to get when it worked were extremely varied and I couldn't stand trying to get all the powder out of those tiny packets. Need to rethink design on those. Not pleased unfortunately.
Great Checker By KerryF on 3/29/2016

One star off for those silly packets for the reagent. Works well and seems very accurate. Lid seems to have a hard time staying closed with a vial in it the checker...no big deal really.
Nice for Accurate Low Range Testing By Michael on 3/18/2016

Like many other Hanna checkers this product takes the guess work out of phosphate testing. I have a special loathing for trying to decipher color coded phosphate test kits and this helps me solve that issue. I had to take 1 star off because getting the power into the vial is brutal, and I mean brutal.
It works, just have to get use to the reagents. By jay on 3/5/2016

Good too have two vials. One to set the checker, the other one to have the reagent all ready mixed.
