300 Gal Stock Tank


The house we moved into has a 300 gal. Rubbermaid stock tank surrounded by landscaping stone near the deck. I'm thinking about setting it up this spring and using this pump/filter/ fountain kit by Pond Master:


The 1500 model pumps 500 gal/hour.

I don't hear much here about submersible pumps so I'm looking for opinions and input.

I would go with more water movement than that. Also, I am not too fond of those boxes in the pond. IME the roots find them, and the sponge filter gets invaded pretty fast.


This company's products are good, and can be purchased at Ewing Irrigation and probably other landscape supply places.

OK. There are models that pump a lot more gph...

The link offered seems to have a lot of products, which are you suggesting? I'm looking for simple. What if I just take the filter out and inspect it once a week?

Be patient, it is a big catalog.
Look at page 10. See the 'concept' drawing. The box with a cut away view into the interior. The pump is not just in a box, but there are also baffles that keep the roots out, and trap debris.
This product is intended to be placed outside the pond, next to the pond, using flexible pond liner. Something like it, but smaller, works better inside a hard surfaced pond (stock tank or other). The idea is not just a mesh box with a sponge, but a better intake system.

Then scroll to page 11. See the tower-like thing on the far right? It has a grid-like thing attached at the bottom. The pump fits in the tower. The lid can be submerged or not, whatever fits. The grid-thing extends along the bottom of the pond. This is where the roots would get in, I am afraid, but at least there is plenty of room for them to grow before they are a problem. Can go longer between having to clean out the roots.

Or, go with the style you pictured, but yes, monthly or even weekly cleaning when the plants and fish are highly active. Mine needed weekly cleaning and I could not keep up. Burned out the pump. If you start with something like this, perhaps add another box with coarser media around this box.
Here is one possible box. I have also used the crates that grocery stores get milk and similar products in, and a Matala sort of mesh as primary filter.

OK. After thinking about the outer box idea, I get you. I need to keep the cost down and the setup I found is around $100, but I could add the crate and mesh around it.

Sock - I ran a small 300+ gl pond for several years with a silent giant submersible pump. Wasn't the prettiest and I'm sure not the most efficient but, it did work year in year out. I had the pond running April to Oct.

I ran the water into several incarnations of a gravity trickle filter. Hardly a NASA inspired design. Course foam over a pile of lava rock, pea gravel & out to the pond. Overflow 2" above the Foam all in a 5 gl bucket
