Hello fellow members !!!
I have a 2500 in-ground pond in the Florida sun.
Filter is an old Nitramax by AZ Ponds. ( A converted pool sand filter )
This filter doubles as Biological and Mechanical filtration but it doesn't filter very well mechanically and it doesn't back wash unless I manually stir the media with my arm before switching the valve to back- wash mode.
Lately the filter has been showing its age. I thought about rebuilding the valve but it is fairly obsolete.
So my options as I see them are as follows:
A Pricey Koi Pond Filter such as the Ultima $$$$
A new pool sand filter that I would adapt to koi pond duty by changing to a koi pond media instead of sand.
A DIY design such as those floating around the web.
Any filter I decide to implement will change the basic lay-out of the pond as far as the filtration goes…. I will change the location of the filter, reduce the number and angle of piping bends to and from the filter, add a pump pit so as to lower the pump below the pond water level, add a pre filter and or possibly a Siff style filter.
An absolute MUST in this project is that the filter be able to back-wash.
I’m a little undecided about the DIY type since I’m not aware of any of these that truly back wash.
Any ideas, comments etc greatly appreciated. J
BTW For some reason I’m not able to view photos in this forum .
Thanks in advance for your advice.
