Hi everyone I have just built a little larger pond it’s 6ft x 5ft approximately 1600 litre I am having a waterfall blade what size filter is recommended it’s about 3ft across bottom of pond and just over 2ft up to blade from what I’ve read it’s says about 4000 litre per hour needed is this right my present filter is 1500 and I don’t think it will be powerful enough any advice is appreciated
