How to slow down fish pond pump

[portisheaddan]

Hello everyone in here. I am new to the forum so saying hi!

I am after some advice regarding an electrical garden fish pond pump.

I have bought a pump that is quite honestly to big for my pond. Its pumping too way to fast - twice the speed i need. Although I have a knob on the side that I can turn to restrict the output, this wont slow the pump down and will still consume too much electricity.

My question is - Although the pump is sealed - Is there a component/components I could get at say maplins etc that I could solder or put in line to reduce the power or voltage to the pump ?????

Make any sense?

Is there any way or doing this? It has to be cheapish other wise I may as well buy a new pump.

Thanks everyone

What you describe is a "brushless motor" ...... usually very reliable bits of kit

mine has been in use 24 hours a day for 19 years. because I don't use a pre-filter but pump unobstructed to my filtration system it does pick up grit etc. I have replaced the impeller 4 times. I bought 6 replacements with the pump as I know how reliable they are.

I can't imagine that throttling the flow back on one of these back would be any problem.
