I have a garden pond with about 30 goldfish. The depth is 2ft and capacity 1000 gals approx. My old pump was a Trident Otter Maximus 5000 and has lasted 4 years. Can anyone recommend a pump which I could get as a replacement that they have and have found satisfactory with a good flow rate and minimum maintenance. I am a bit tottery on my pins so like to keep the amount of time working on the pond to a minimum. Thanks for any replies in advance all are very welcome.
