Simply Koi and More Koi

Hi,

I have a pond that holds 3750 gallons and i use a nexus 200 filter, the pond is not very heavily stocked but the filter does struggle and i have to clean it every day otherwise the filter overflows and i loose loads of water quickly. i was thinking of puting a vortex filter before my nexus, but my nexus is pump fed, and my local shop says i can only use a vortex with a gravity fed sysem? is this right??


Regards

Jason

Hi Jason,

Welcome to Koi Quest

There must be a reason why the filter is blocking so fast so we may need a bit more info is it and eazy type and how is it set up and size of pump

What is it that is making it block is it waste or blanket weed

Hi thanks for the reply,

i have an aquamax 12000 pump its an easy and although there is a bit of blanket weed it seems to be normal pond waste, i have tried to clean the outer chamber via the small valve at the side but it does not drain it and am wondering if its blocked up some how. the filter runs fine after its cleaned?

regards

Hi Jason
What size air pump do you have in the Nexus?

your pump may be to much, i know you will have some head loss the nexus 200/210 max flow is 10,000, that is perhaps why over time it over flows.

If you have lots of short bits of blanket weed breaking off and sticking to the outside of the Kaldness screen, this will cause the water level to rise in the entrance channel and the pond side of the filter, I stuck a long brush in between the screen and the wall and it does give you little extra time before your clean. But the only real answer is to get rid of the algae.
