So, speaking of pumps . . .

[JPaul]

Still in the planning stages, but the basic facts are:

• 10' x 6' x 2.5' Pond (~1120 Gal) to be filtered largely by 8' x 2' x 1' Bog (~ 120 Gal)
• Assuming pump at the far end of pond relative to bog, distance to be pumped is approximately 10 linear feet and 3 vertical feet
• Not planning on any other waterfall needs other than the overflow from the bog

So, I want to go ahead and purchase a pump. It sounds like I want to have a turnover of at least 600GPH, but given the configuration would 900 be sufficient?

And if so, would something like this be a good choice? http://www.amazon.com/Laguna-Max-Flo-Waterfall-Filter-Pump/dp/B000HASBHC

I would think the gph would work, but I don't use submersibles, so can't help you with that.

I don't have a Laguna submersible at this time. I have a Pondmaster and it is good but the Laguna is the one I want for the future. It takes less electricity. I have a 2500 gal pond w/ a 2400gph pump and I want a 4000 gph Laguna or whatever size it is, might be a 4200 gph not sure but I have a waterfall that I like the water to come out faster and harder but for what you want I think the 600 or 900 would be fine. You could go bigger and just use a y to divert excess water to a spitter or a fountain or whatever else you would want in the future. You can always tone them down a bit but you can't make them flow more once you buy the smaller ones.

But you can always buy a small pump, use it, then buy a bigger pump later, giving you a backup. I don't regret having a spare pump in my shed one bit. Gives me peace of mind.

I absolutely agree with buckry on this one. I actually have two pumps running constantly in my pond and an additional one in the garage should one fail.

We have three in the basement, on standby, just undo the rubber connection, stick in a new pump, down for minutes, well might be a little longer than minutes.

 

[JPaul]

Thanks, all. I never would have thought of having a backup until it was too late.

 

[buckry]

Now I have 2 backups, replaced my last 900gph with an 1800gph, just to make the waterfall look beefier. Very happy with the look, and very happy to have 2 backup pumps. Although, that's going to be a really bad day when I use my backup and my backup backup pump. Probably never happen.
