The pond is 10' long x 2' wide x 1' deep. The pump is at one end and water is raised 1' to a buried garden hose that is maybe 12' long and then at the end it goes up 2' to release the water over some rocks. I had a 330 gph pump that worked well but died. That size has been discontinued. Go smaller or bigger? DON
bigger is ALWAYS better when it comes to this application! do you run your water through a biological filter medium of some sort? the ideal circulation rate for biological filtration is 3 times or more per hour that the entire volume of your pond water to be circulated.
the pro's for having a liner is which you have greater freedom to create your person pond and how that's formed and the intensity of it. The con's are somewhat that it takes some paintings, quite in case you're digging it by potential of hand. With an pre-shaped pond, the paintings is greater basic yet you're constrained to the layout and intensity by potential of what's given to you. some pre-kinds do no longer supply sufficient room in case you will desire fish and vegetation and ornamental freatures like rocks. My opinion is to place a pond in with a liner. I somewhat have build some and it grants greater freedom to create. I make certain I somewhat have the pond deep adequate. in case you will desire a water lily, some desire to be put in 2 ft of water. in case you will desire fish and desire to over wintry climate them interior the water, they ought to have a minimum of two a million/2 ft of water (nevertheless I deliver mine in during the wintry climate in a tank I somewhat have interior). I additionally desire to have some shallow areas in my pond. Birds can bathe and drink the water and that they seem to be a good allure to the pond. reckoning on the dimensions of the pond, you should make certain you have a huge adequate pump and filter out equipment. To small of the two, and your pond will seem undesirable. One pond I put in did no longer have a filter out equipment in it and that i had a lot of alge and the pond grew to become into merely a multitude. I put in a filter out the subsequent 3 hundred and sixty 5 days and it grew to become into an incredible purchase greater useful! putting in a 'liner' pond would fee a sprint a sprint greater and be a sprint greater paintings, yet think of that's somewhat worth it. this way you're unlike every person else that has there little 'insert' pond.
Hi Don, In my point of view it depend on the final effect that you want to create. If you are in the mood of water theraphy, mean that you like to the sound of the water fall, you may want to consider a pump size that a bit higher than your previous ones, and vice versa. In a nutshell you should be able to determine the effect of the waterfall you need since you already have your previous old pump running before.This should be your best guideline to check the size of your new pump needs. There is a bit of extra caution needed if you are thinking of using a bigger size of pump, you should ensure that the pump are not sucking to fast of the water. If this is the case you might be end up having your pond drain half tank. You can get the circle time for the water flow base on the pump size from the catalog.I'm sure your hardware guy are gladly assist you in understanding the matrix conversion Pond size over the pump size,since I can't explain in detail here about the graph reading. But in most cases I just relatively using the first option of comparing the old pump size with the new one. Hope that help. Fazla
