I’ve not had that exact brand, however I know from experience and googling the filter itself, it will not cope with the size of your pond.
Your issue is going to be, in a years time you can’t return it and you will be looking for a new one, you will likely be able to return it and pick a 2nd hand one up for half the price which will manage the size.
If you don’t want to take the advice of myself or anybody else on the internet.
Try and find someone locally who has a similar size pond and ask them what they think.
Cheers,
Pond Man
