  1. Awesome Product don't hesitate when purchasing!!!! Review by TJHOWELL
    Product Rating:

    I don't know why people would waste any money on other products for testing phosphate. This is hands down the best way to test for it and the most accurate. Very simple, the reagent packets are a little bit of a pain but once you figure out how to get all the powder out its pretty easy. Don't waste anymore more money on other test kits for phosphate just buy it. (Posted on 3/15/2018)

  2. Great product Review by Sergey
    Product Rating:

    an excellent product, greatly facilitates the life of the aquarist, you no longer have to try to determine the color visually. the reading is 3-4 times more accurate than that of 713 (Posted on 1/9/2018)

  3. Never buy another po4 kit Review by GnarleyMarley
    Product Rating:

    Hands down best low range po4 kit available. I run a 120 sps dominant reef and i like to keep my po4 around 0.02 with this checker there is no more guess work, the digital readout ensures confidence, No more wondering if that color is supposed to exactly match the color card even tho it doesn't. Best purchase in a while! (Posted on 1/5/2018)

  4. Easy to use product Review by ABishop

  7. Great product to monitor Phosphates in the ULNS Review by PiscesPower
    Product Rating:

    I love my phosphorus checker. My Triton system runs very low phos and I like to keep a close eye on things, trying to get a little bit of phos but not too much. The ULR lets me manage it without big swings. (Posted on 12/8/2017)

  8. Detects phosphate but I don't have any Review by karlandtanya
    Product Rating:

    Using the HI713 I never detected any phosphate, so bought this one instead.
    NOTE--this one is calibrated for *phosphorus*, not phosphate, so is only about 4x as sensitive as the HI713.

    Anhyow, the HI736 still still didn't detect any phosphorus in my tank, so I made a dilute solution of TSP just to see if the thing even detects anything! Short answer--yes, the testers do report phosphorus/phosphate when it's really there.

    Anyhow, the HI713 and the HI736 *do* detect phosphate when it's present but reported more than I expected from my dilution. This was just a sanity check with Savogran TSP cleaner--not lab reagents, so don't expect accuracy (correct numbers)--just precision (repeatable numbers).

    For what it's worth, the HI713 and HI736 did report consistent (repeatable) resultss to 3 significant digits (after correcting for phosphorus/phosphate) when testing from the same sample. (Posted on 1/11/2017)

  9. Great product Review by Dan
    Product Rating:

    Simple to use and provides a nice easy to read digital read out. I have heard that it may not be as accurate as sme high end photometers but for the price and easy of use it is great and beats the color interpretations of other test kits (Posted on 4/8/2015)
