how many of you use a sump filter for your pond? i see alot of DIY gravity-fed filters, and some pump driven filters, but anyone have a good experience with a sump filter for their pond?
 
I think people use sumps on tanks because they can be hidden under the tank in the stand, and when the pump shuts off and the water drops an inch or two its not that many gallons. On a pond if you wanted to use a sump you would have to compensate for the large surface area of the pond. On a 10'x25' pond if the pump shuts off and the water drops just 2", over 300 gallons would flow into the sump, so it would have to be very large to keep from overflowing.
 
a sump would only work on above-ground ponds, not in-ground ponds...
 
hmmm. well the pond is mostly in ground. the water level will be 3 feet i n the ground and one above ground. but the edge is 2 feet above ground, put it in ground for the insulation during winter.
 
im debating between 13,500 (30x10x6) and 20,200 (30x15x6)..... depends on if i do another pond or not, could go larger if without another pond, then it would be 20x40. but ive seen some sumps for up to this size, they base them off of surface area i think right?
 
man, if youre going something that big, id run dual pressurized bead filters...
 
Why rule out other ways? does it have to be a sump for a special reason?

As your building a foot above ground then gravity will offer a lot more flexibility down the line

may be 4 feet into ground, really depending on how much volume i want, not sure yet, but at least 30x10 for surface area, and probably at least 4 feet deep. so about a minimum of 9000 gallons.

i wanted to do a sump because i think that if i did a diy gravity system, i would lose track somewhere of what i was doing, and then i would just be left with a bunch of parts.

but if i did do a diy, it would be gravity fed. dont mind building the little extra pit to do it in, i probably wont be installing this pond, probably going to have it built, so it can be poured in as solid concrete.
