Hi James
Looking at the demensions for the size of your pond you are looking at around 3,000 gallons or there abouts, I would recomend the Aquamax 10,000 or the sequence (750) now know as the 10,000. Both of these pumps have been very reliable for many people over the years and served them well.
The Sequence is a pump which has to be run dry, Where as the Aquamax can be run submersed or as a dry pump. I must point out the Aquamax 10,000 is the old model which has been replaced with the 8,000 or 12,000 pumps but i have heard it say a lot of people prefered the older models.These older models can still be purchased at a few koi dealers up and down the country at a very reasonable price now.
I have 2 Aquamax 5,500 on my pond which i run dry and a Aquamax 10,000 on the skimmer which is also run dry.No problems yet but then a again mine is a new pond and only been up and running for the last three months.
The reason i put two 5,500 on the filters instead of the 10,000 was because if there was any kind of pump failure on one of the pumps,i still have one running while the other one can be repaired. Iknow the initial out lay was more but in my opinion was well worth it for peace of mind.
Forgot to mention the Aquamax has a 5 year guarantee and 10 metres of cable.
The Sequence has a 1-2 year guarantee i think but dont quote me on that,may be someone else on here could confirm that.
Hope this helps.
Regards Shaun F.
