Thanks for this - I nearly bought one, thankfully I watched this and avoided a ton of hassle with matching hose connections.

The sponges and foams in your pond filter are an important part of the biological filtration process. They are designed to be a safe haven for the good bacteria that forms in your pond which consumes ammonia and other toxins and converts it into substances which are less harmful to fish.
This bacteria takes 4-6 weeks to grow. When you clean your filter sponge with chlorinated water, such as water from a mains tap or garden hose, all of the good bacteria in the sponge are killed by the small amount of chlorine in the water.

One obvious question I have is why you bought and installed a 4000 model for such a small pond? Seems overkill? What's the model number of the newer big one you purchased ?

[johnshaw]

Are you not supposed to be able to divert the output and clean the foams without opening the can up?
