100 gallon pond

[MartinJ3]

I have a 100 gallon pond (no fish) and from what I've read I should use a 50 GPH submersible pump. I really only want to keep the water circulated so it's not breeding mosquitoes (nothing fancy). When I plugged in the 50 GPH pump it barely circulates the water. What size pump would you recommend, 100 GPH? I'm obviously new to this. Thanks for your help in advance.

Usually , turning the water over at least, once per hour is recommended....so a 100 GPH. If you're not going to have fish, then it would be up to how you like it

With a pond that size, an air pump and with an airstone might be enough water movement.

and some times may be cheaper to run but if you want a fountain then not as good

True @sissy - but for water movement it would work.

I started with a 35 gallon tub and a 260 gph pump. I didn't feel that was too much water movement in a little fountain. Neither did the fish. But with what you have, just get what looks nice to you. You can probably find a 200-300 gph pump with a dial to restrict flow if you find it's too much.

The amount of water flow depends on the diameter of your tubing, the length of the tubing, and how high the water goes before it water flows out. This is referred to as the head. 50 gph may not be 50 gph.

Since you don't have fish, I don't think it matters. I had a 250 GPH pump for my 3500 GPH pond forever until I added fish. You just want something to move the water around so it doesn't stagnate.

What would you guys think is a suitable GPH pump? The 50 GPH offers almost zero water flow

What are you pumping the water through? Do you have some kind of fountain or spitter?
