  • Measures Phosphate Levels in Aquarium
  • Quick and Easy to Read Results
  • Helps Identify Excess Phosphates That Cause Algae

The Phosphate test kit from API is used to measure the levels of phosphates in the aquarium. Phosphates are necessary in small amounts for plants to thrive and should be present in planted tanks. However, excess phosphates can cause excessive algae growth and can harm fish health given high enough levels. It can be found in the water column of your fish tank from fish waste, decaying organic matter such as dead leaves or can even come straight from tap water. Ensure the level of phosphate in your aquarium is up to par with this easy to use test kit.

Useful Kit!

Phosphate isn't often talked about in the freshwater world but may be a useful parameter to monitor. If you have Black Beard Algae, Phosphate may be the cause. So check your water source and tanks for Phosphate with this easy to use kit to manage your aquatic environments at a higher level.

Great

Shipped super fast and didn’t realized that phosphates were off the chart, I felt there was something off about my aquarium thanx to Cory’s videos I didn’t even think about phosphates until I saw the video. Bought the kit from co-op because I like the service and products they provide. Learned that phosphates were way to high despite water changes and low feeding and decreasing ferts. Trying the their phosphate pad and hopefully that will bring it down

Must-have kit

It’s really good to know your phosphates especially if algae starts to show up. This kit helps you correctly balance water chemistry in a planted tank.
