Envirascape stone pond the pump is not getting water up to fountain

impellor stuck. not sure if you can get to it though

It is presumably a submerged pump. Cleaning the pond could have accidentally blocked the pump inlet or damaged or dislodged the supply pipe.
Time to wade in and take a look...

I need an instruction manual. I got this for my birthday but when I wanted to put it together there were no instructions to be found. You can send it to my email [email protected] thank you.

You have some debris floating around somewhere. If you are pumping from a pond or a rain-barrel, you might have debris clogging the inlet. Or maybe you have a stone in the impeller - if your outlet is on top of the impeller a stone will sink to the bottom so you could have flow initially, but the stone would be carried up to clog the outlet within a few seconds. Or you might have stone in the hose feeding into the impeller - that stone could roll back down the hose even though you don't loose prime.

there is traped air in there you are going to have to lift the edge of it and let the air out

Check the strainer at the pond. Prime the pump and see if it pumps anything.

You don't need a bulkhead if your liner is EPDM. You can use a boot that is attached with adhesive that will seal you pvc piping. I don' t see a problem with dirty water going thru the pump before the filters. for some diagrams of settling tank installations see:

The best solution to ice in garden ponds is to keep the water moving as moving water will not freeze. Depending upon the size of your garden pond you may try adding a fountain. All major pump brands carry small fountain pumps that include various fountain spray nozzles/heads or you can buy the pump and then purchase a Fountain Head Kit separately. The fountain will provide 1 - movement of water at the surface, 2- aeration for the pond, 3- pleasing sounds year round, not to mention the 4- aesthetic value. The added bonus is that you will not have to worry too much about shorts if you use a submersible pump. So try dumping the deicer and go for a fountain.

I live near Memphis TN so don't have that pesky "frozen water" problem. However, I do aerate my 2,500 gal goldfish pond with a Oase Biosys Skimmer (free standing/ floating skimmer) which is powered by a Laguna fountain pump. I attached a small pipe on the discharge end of the pump & set the pump so that this pipe is a few inches below the water's surface. The discharge provides a small fountain effect that keeps the surface moving while aerating the water. The skimmer keeps the leaves / debris off the top of the water the pump keeps the water moving...and moving water will not freeze. Hope this helps

There are basically two types of pond pumps to choose from - externally mounted and submersible. External pumps were traditionally used in water gardens. They sit outside the pond, with a hose that leads from a strainer in the pond to the pump. From there the water is forced either to a waterfall, stream or fountain. Because external pond pumps are often noisy and require extra plumbing, they are usually not suited for most backyard ponds. Due to easier accessibility and ease of repair, however, external water pumps are often the best choice for larger water gardens and public installations. Submersible water pumps are usually preferred by most do-it-yourselfers. They sit underwater where they are quiet and unseen. These pumps are easy to install, require no priming and stay cool thanks to the surrounding water. Submersible pumps draw water from the bottom of the pond, either through a strainer or biological filter. A hose attached to the outlet then feeds water to whichever water feature you have installed.
