PSI | Pond Aeration |
Malibu Water Resources Directory 2 | 

---

To determinie how much PSI is needed
to get air down into water in a pond, use this calculation for water depth and PSI:

---

PSI: 2.3 ft = 1 psi
PSI = pounds per square inch of air pressure

---

---

1 psi = 2.3 feet
2 psi = 4.6 feet
3 psi = 6.9 feet
4 psi = 9.2 feet

---

5 psi = 11.5 feet
6 psi = 13.8 feet
7 psi = 16.1 feet
8 psi = 18.4 feet
9 psi = 20.7 feet

---

10 psi = 23 feet
11 psi = 25.3 feet
12 psi = 27.6 feet
13 psi = 29.9 feet
15 psi = 32.2 feet

---

16 psi = 34.5 feet
17 psi = 36.8 feet
18 psi = 39.1 feet
19 psi = 41.4 feet
20 psi = 43.7 feet

---

21 psi = 46 feet
22 psi = 48.3 feet
23 psi = 50.6 feet
24 psi = 52.9 feet
25 psi = 55.2 feet

---

26 psi = 57.5 feet
27 psi = 59.8 feet
28 psi = 62.1 feet
29 psi = 64.4 feet
30 psi = 66.7 feet

---

40 psi = 92. feet
45 psi = 103.5 feet

---

---

The Koenders air compressor, new from the factory
can produce 25 psi to 28 psi. That is enough to aerate a pond that is over 30 feet deep.

This is the Koenders air diffuser and foot valve assembly.
