Elos Aqua Test Kit - Phosphate Information


Phosphate (PO4) build up in aquariums appears to be a fairly common problem in freshwater and saltwater aquariums. They are present in most tap water supplies and are also introduced to aquarium water through fish waste, uneaten fish food, and decaying plant and invertebrate material. Hobbyists end up with rising levels of PO4, leading to the appearance of algae that start to cover the tank panes, the substrate and just about anything else in the tank. The maximum value of PO4 in an aquarium is 0.01 mg/l (ppm) for saltwater aquarium and for fresh water aquarium is 0.5 mg/l (ppm). In deeply planted aquarium the maximum level can achieve up to 1 mg/l (ppm). The periodical analytical evaluation of phosphate in the aquarium should be considered by the serious aquarium enthusiast.

ELOS AquaTest PO4, as well as all the other colorimetric test kit of this line, grant very high precision thanks to several procedures like the use of "RealColor" technology, an accurate system to calibrate the color chart compared to the reagents; the validation of each reagent with NIST (National Institute of Standard and Technology) certified samples and the careful stock management to supply to our customers ONLY the freshest production batch. Our PO4 test, allows the determination of the Phosphate down to a level of only 0.01 mg/l (ppm) Phosphate presence.

  • Great for most reef and freshwater aquariums.
  • Range 0.01 - 1.0ppm
  • Color Scale (ppm): 0.00, 0.05, 0.01, 0.25, 0.5, 0.75, 1.0
  • Easy reading: "RealColor" technology.
  • High precision: thanks to the use of calibrated droppers
  • NIST validation: each batch of elos reagents is validated using NIST (National Institute of Standard and Technology) samples
  • "Safe reagents": reagents and testing procedures are based on Low Risk Reagents. None of our test kit are based on Toxic Reagents.

Comments: The test kit is very very easy to use, my only complaint is that the color chart can be a little hard to read to get more accurate test results. But I'm not sure there is a way around this. I would definitely buy it again.

Comments: The typical problem with these kits is the difficulty of matching the color through the tube and the paper. This kit keeps that tradition, but it was easier for me to read than most comparable kits. If you're looking for a quality testing kit with simple directions and quality of use - this will get you where you're going

Comments: Some of the grays are harder to distinguish between them in the lower PO4 levels. Best kit I've used with no false readings. As with and PO4 range kit, make sure to rinse test container well after test.

Comments: I find the kit very easy to use, fast, and accurate. The color change in the vial matches the color chart exactly. The results are not ambiguous at all. I would highly recommend this kit to a friend.

Experience Level: Intermediate

Comments: This test, like the others made by Elos seem to give incorrect results, are over priced, more complicated to perform (versus API and Seachem) and the lids to the vials do not even fit properly so when they expect you to shake them for 5 full minutes, you end up with about half the water left in the vial then you started with. I am very disappointed with the Elos testing product line.

Comments: the middle range colors look almost identical on the supplied color chart. i found it impossible to tell the difference. it was the .25 and .5 the colors range that i use would most often. the kit does supply an accurate syring measureing device but overall not stoked with the performance.
