Filter Clogging Problem

[sailmike]

We have a Tagelus high rate sand filter for pools and spas for our pond here in Southern California. Also, there is an underwater pickup going to the filter with a plastic strainer on it to keep out large matter. The pump is a 3/4 hp Hayward max flow rated at 11/5.5 amps. The waterfall flow rate keeps going down to a trickle every 3 or 4 days and we have to backwash and rinse it every other day to keep the flow at a good rate. This is my parents pond and I don't think that's normal. We shouldn't have to backwash and rinse so often. So, how do we fix this?

Thanks,
Mike

low flow running to polish the water they do the job.. full time filtration, not so good. build a bio filter..
