Koi & Pond Tip of the Day
July 25th, 2016
To clean a filter, all you need do is lightly rinse the media. You just want to remove any debris that is restricting the flow. A good way to clean many types of media is to slosh it in a tub of pond water or rain water. Fiber media can also be knocked against a surface to remove some debris. If you have multiple types or layers of media, you also rotate which get cleaned to help ensure strong bacterial colonies.

Hakko Diaphragm Kits

Hakko Diaphragm Kits

Our rebuild diaphragm kits are simple to install. Refer to our trouble shooting section for directions on proper replacement procedure.

Tools you will need:

- 1 medium phillips screwdriver

- 1 small phillips screwdriver

- 1 medium pair of pliers

Note: If your diaphragms are blowing out frequently, you most likely have an excess back pressure problem in your design. Check that your air delivery tube is large diameter and no kinking is occuring. Check your air diffusers for clogging. Ceramic style air stones need cleaning with muriatic acid every 3 months typically. Check that the number of air diffusers is sufficient to handle the air output of your Hakko pump. Too few diffusers will create excess back pressure. Read the article titled "Heat Control for Air Pumps"

Hakko Replacement Magnets

Hakko Replacement Magnets

The magnet is the part that moves back and forth with the diaphragm. It holds the diaphragm secure and vice a versa. Typically the magnet is very long lasting.

However if you run the air pump with bad diaphragms for extended periods you could wear down the magnet. If you open the motor for repair and you find dust or small metal particles you may need to replace the magnet. Always inspect the magnet for wear and tear when you replace your diaphragms. They are very easy to replace. Call us if you need help.
