Which Hanna Phosphate checker is best?
The Hanna HI736 Ultra Low Range Phosphorus Checker is more accurate at low ranges than the HI713 Low Range Phosphate meter. Many reefers argue that the phosphorus checker is a better option for those reefers who are looking to maintain ultra-low nutrients right at the cusp of 0.00 ppm.
What is a good phosphate level in reef tank?
0.05 ppm
The optimal phosphate level, especially for reef tanks, is an immeasurable one, or zero, with 0.05 ppm-mg/l being acceptable, and an upper of 0.1 ppm cited as well. Having a good, reliable phosphate test kit is important.
Are Hanna Checkers accurate?
ACCURACY. Hanna Instruments HI755 advertises accuracy @ 25°C/77°F is ±5 ppm (mg/L) or ±5% of reading, which, in hobby level test kits standards, is highly accurate. To be fair, all good-quality marine test kits available on the market have similar accuracy.
When should I test my phosphates in my reef tank?
It’s important to measure phosphates weekly in a reef tank because if the levels get too high (over . 05 ppm) it can prevent coral calcification or cause excessive algae growth. (It’s also a good idea to test the levels if you notice an excessive amount of algae in your tank.)
Is 0.25 phosphate good for reef tank?
For most reef tanks that are no more than 2-3 years old, phosphate levels should be kept very low in order to avoid problems. You’ll find recommendations ranging from 0.02 to 0.05 ppm are the most common answer.
What is an acceptable phosphate level?
In 1986, the Environmental Protection Agency (EPA) established the following recommended criteria for phosphorus: No more than 0.1 mg/L for streams that do not empty into reservoirs; no more than 0.05 mg/L for streams discharging into reservoirs; and no more than 0.024 mg/L for reservoirs.
How long do Hanna test kits last?
Hanna’s line of calibration solutions have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened sachet.
