As per the title, looking for any endorsements for a pump with good head height for regularly doing 300 litre plus water changes (or more precisely the refill part of the process).
Needs to be able to clear 150cm height and be able to pump at least 600lph at that height to keep refills to under 30 minutes or ideally a lot faster. Happy to stand there and direct the flow of water if it takes sub fifteen minutes (1200lph @ 1.5m height). Adjustable flow rate would be even better, start slow to not disturb substrate then whack it up once tank is half full.
I know there are other methods but will be refilling from barrels warmed to temp and dechlorinated next to the tank. The goal is to make this as slick as possible and the component that is missing to achieve that is the speed of the refill.
Really just interested in any product that anyone has tried and tested. Doesn't even have to be the cheapest it just needs to be reliable and fit for purpose.
Thanks in advance
