Pond pump/filter

Hi

Have small pond, that has a pump and fountain at the bottom of the pond and a filter box next to the pond.

Is it possible to get something that doesn't need to be in the water (pump).

Have to clean the pump a lot, was hoping I could get a filter and pump all in one?

Why are you having to clean the pump a lot, is your pond full of debris?
You could always try putting a plastic mesh pot over the top of your pump (weighted down with a stone/brick) so it acts as a debris filter before the water gets to the pump? a lot easier to quickly pull the mesh pot out to clean than it is to clan the pump. https://www.bradshawsdirect.co.uk/a...gs8WYi5pvkO2mKlyeFEl1EjC_UpSEz-gaAhWEEALw_wcB

I currently have to pumps in my Koi pond and i've never needed to clean the pumps in roughly 3 years since they were put in.

Another pond owner here. Can you give an idea of what happens? What is blocking?

For example my pump is 1.5m down but the waterflow and the full sun causes string algae to grow - that acts like a filter and slowly clogs up. The pump then needs cleaning.
My canister is fine for a two week cycle when I give it a “cleaning cycle” (switch output and rotate the handle) and a yearly open up completely.

Hi

The pump isn't blocking up as such, it's just when I have checked it, it's got brown sludge build up and covered in green algae?, since then I like to check often (once a month) and clean it just in case it does actually block up altogether. Perhaps I haven't got anything to worry about and this is normal.

My pond is only small, have gold fish which are very old and frogs, I have some plant life in the pond as well such as lilies and a grass that grows very tall which often needs to be controlled as it spreads quickly.

Perhaps I could do with a better pump, it was only a cheap one I believe but has lasted a long time.

Any other tips to keep the water clean that may prevent the sludge build up at bottom of pond?

Thanks very much

Can’t get photos yet, but the filter box gets sludged up quite a bit, we hose the filter sponges down , maybe I need to get a better filter box.

If you can work out the volume of your pond in litres (width*height*depth*1000 - using metres) that should help you figure out your filter needs. Also see my note about not using a hose from earlier.

I have a multi-stage fibreglass filter, like the below (different manufacturer mind). They provide different chambers with different levels of filtration. Not cheap, but they get the job done. I do use a hosepipe on the filter brushes in the initial chamber, but the rest I just clean in pondwater to save the bacteria.

Thank's for the information, will check all that.
