Air Hose - Hakko Air Pumps



Air Hose

Matala Weighted Air Hose is a self sinking air hose designed to sink to the bottom of your pond without additional weight. It is available in 3 sizes; 3/8", 5/8" and 1.0". The black color easily disguises it on the pond bottom. You may purchase it in 10 foot increments or 100 foot rolls. The 1.0" is available in 50 ft rolls.

Below is a table showing the recommended hose sizes for our Hakko Air Pump products.

HK-25L HK-40L HK-60L HK-80L HK-100L HK-120L* HK-150L HK-200L HK-250L
3/8"
1/2"
5/8" X X X X X
1" X X X X

* The outlet on the Hk 120L is 1.0". Do not use smaller hose than 1.0" for the HK 120L. It requires this size hose in order to run cool. If you use a heavy duty 4 way manifold with the HK120L, you can use four 3/8" hose to deliver air to 4 diffusers. See the article Heat Control for Hakko.

Koi & Pond Tip of the Day
June 26th, 2017
The bacteria in a biological filter converts ammonia to nitrites and nitrites to nitrates. In a water garden with plants the nitrates are used by the plants. In a koi pond, or other pond with few or no plants, the nitrates just continue to build up in the water. Nitrate is far less toxic than ammonia or nitrites, but if allowed to build up for too long it will present problems. At least every 3 to 5 weeks a partial (about 10 to 20%) water change is needed to reduce nitrate levels in fish ponds.
