Potassium: at least as important as iron!

Potassium is a macronutrient and at least as important as iron for a good and healthy plant growth. Therefore it is important to check the level of potassium to prevent too low levels and keep them in a healthy range ( 10-15 mg/l). The Easy-Life Potassium test is a color test with a color chart.

Optimum level for a planted aquarium

Aquarium plants benefit from 10 -15 mg/l (=ppm) of potassium. A level below 5 mg/l (=ppm) is not desirable and can lead to growth problems, yellowing of the leafs and deformations, Often lack of potassium is confused with lack of iron, also because potassium was very difficult to measure until now. If the level is too low, extra potassium will help the plants te recover soon and they will color deep green.

Very sensitive and easy to perform Phosphate water test

The very sensitive and accurate Easy-Life Phosphate testkit is suitable for fresh water and marine aquariums. There are two different ranges within the testkit. A low range from 0.00 – 0.10 mg/l (ppm) and high range from 0 – 2.5 mg/l (ppm). The Easy-Life Phosphate water test only needs 1 reagens!

Easy-Life Phosphate PO4 test

• suitable for fresh water and marine aquariums
• easy to use, reliable and ultra sensitive
• colortest, easy to compare with a color chart
• PO4 detectable from 0.01 mg/l (=ppm)
• low range: 0,00 – 0,02 – 0,04 – 0,06 – 0,08 – 0,10 mg/l (=ppm)
• high range: 0,0 – 0,5 – 1,0 – 1,5 – 2,0 – 2,5 mg/l (=ppm)
• testkit accounts for 75 tests

Note: For a phosphate content above 2.5 mg/l (=ppm) the water sample from the aquarium can be cut with water without phosphate (distilled water, RO water or tap water often). The PO4 concentration higher than 2.5 mg/l can be determined.
