Hi Akasha,
Many thanks for your reply. My filter looks exactly like your photo. When I took the pump and housing out I could see that the intake was blocked by weed. I did not manage to remove the pump from the housing but clearing the intake has cured the problem.
Many thanks for your help...
Hi my name is Michael and I am new to the forum.,
I have a 2ft. Juwel tank. It became infested with a weed, a bit like the blanket weed that you get in a pond.
I have got rid of it but I think some may be obstructing the pump. The output is very much less than it was.
I have cleaned or replaced...
