Una excelente marca,y he visto el crecimiento de mis tilapias

UPDATE 6/27/21: Since I most recently purchased the same brand pump at a 4500gph, but it won't let me review another gph pump, it will only let me update my review on the 1600gph pump: the 4500gph pump at 2 foot lift is pumping nowhere near 4500gph. Maybe 2000-2500gph. While that is an estimate, I compare it to the temporary 3800gph utility pump i put on the waterfall while waiting for this one to be delivered and the 4500gph is pumping out way less than the 3800gph pump did, so....I don't think this pump is anywhere near the 4500gph it claims to be. I would need to double that size if it's only really pumping half the gallons it says it does. Love the sturdiness of the pump and they have good longevity, but up the size if you want what you are looking for as far as output goes. This pump (1600gph) is so amazing I bought two! I use them in my koi ponds to pump water from the bottom of the pond up into a filtration system and out. This pump is tough and barely loses any gph when pumping at 5' head. Highly recommend it. Ran without issues 24/7 since I bought it in the spring, though I did remove it for winter shutdown, of course. It's pretty much maintenance free and easy to clean if needed (I never needed to) and it's outflow nozzle is adjustable; which I like. You can take the cover off, but it takes some finesse to do so as you have to line up the pump just right to detach the plastic cover. No need to cut it like others have said, you just have to take your time and figure it out. My only suggestion is that they make the step attachment for the outflow bigger so it can accommodate large tubing if needed. Other than that, A+

Great pump works great and very well built.

nice size for a waterfall in a small pond.

It’s not extremely strong before a 500 gallon pond it does a great really turns over my pond in 19 minutes. Amazing I could see all the poo getting sucked up right into it.
