Hi Russell,

Do you have fine mesh or screen before the pump? That got us into trouble
when we first had a pond. Constant clogs from algae and muck. Post-filters
and no fine mesh has solved that problem entirely.

We have a 5 gal bucket around our immersed pump.
Hundreds of 1/2" holes in the bucket. (Pump can handle 1/2" junk)
The water rises through 55 gal barrels that grab big junk in strapping tape.
The barrels are drained each year via 2" pipes in the bottom.
The water moves through 5' pools (12-18" deep) of plants and back over our
falls.
Pools collect muck and are drained each spring.
We have never had a clog.
We have no fine screening or mesh to clog. The slow move through the plant
roots does what the screening does

Jim

I live in Maryland and my pond is about 5 years old. Last summer I
had to clean the pump filters once a month as they would get so
clogged the water falls would stop. I replaced the UV bulb last
summer and have inserted new filters with no improvement. What can I
do to prevent this from re-occuring this year?
