Excellent, less expensive, better and more precise than test strips to test phosphate in clear or salt type pool water

I was surprised my API master aquarium test didn't come with this test. So, I had to order this separately. Phosphate is one of the important macro nutrients for live plants. I realized my tank had 0 phosphate (phosphorous) in it after getting this test. Now I make sure I have some nitrates and some phosphates in my water for my plants. I have to supplement the phosphorous, but not the nitrogen as I get enough of that from fish waste.Another added bonus. I used to battle green spot algae. That tough algae on the glass that would take 20 minutes of scrubbing with a pad to remove. I read that if you keep your nitrate to phosphate ratio at 10:1 it makes it hard for GSA to grow. Sure enough.... I now regularly test and adjust as needed to keep my ratio at 10:1 Usually I have about 10-15ppm nitrates and 1-1.5 phosphates(after adding phosphorous). After a good cleaning my GSA has never returned. So, this test is critical for me and I perform it weekly.

Good product, easy to use, good packaging, seems to perform as stated, but it's not meant for swimming pools, at least not pools that use salt. The "salt water" in a salt pool is not the same as the "salt water" in a salt aquarium. Maybe I didn't read the description well enough, but this is definitely intended for testing aquarium water. Pool stores seem to be pushing phosphate neutralizers these days for some reason. The store where I shop sold me $75 bottle of something to treat high phosphate levels in my pool water. After doing some research I decided they sold me something I didn't need, but I couldn't be sure because I didn't have a way to test phosphate levels myself. This was the closest thing I could find, but it's not comparable to the test kits the pool stores use.

I have a few API test kits and I get consistent results. Color charts are protected an instructions easy to follow. While you can cut the English instructions out on this test kit, it seems API could find a better way to do this across the board in their kits.

Im adding KH2PO4 for my planted aquarium and there was no way to know if I was dosing correctly without this test. It works great and Its very simple.

I have used the API test kits for years and am very happy with the results. More accurate that the test strips.

You must have one of these. Phosphate levels affect both plants and fish, and this doesn't add a minute to your weekly routine.

I have been in the hobby for decades and find API a quality test kit. I really like the ease of use and the quick directions on the back of the color chart with a more detailed instructions included. Check out their other water test kits like the nitrate and nitrite, these with the pH are must have's.

Very easy to use test. Very easy to read chart. Clear and easy to understand instructions. Called the water company to get their phosphate levels, checked my tap, got an accurate result. Now I can maintain my water properties for my planted tank with confidence.

Very happy with the API FW/SW PHOSPHATE TEST KIT. It is so important to test for phosphates to head off algae issues. The kit arrived on time and works well.

This test kit gave me the same results as the pool store's test. Therefore, I would say it's excellent.
