Our Picks

Sand filters are generally marketed as swimming pool filters due to the misconception that they are not suitable for koi. Despite this labelling, they are perfectly safe to use if your water quality allows for it and generally regarded as quite good filters. Let’s take a look at a few and what specifics make them great for koi pond usage.

Suiting up to 21,000 gallons at a time, this filter is powerful and quite effective. The Rx Clear Radiant Complete Sand Filter System is a potent set up that operates as a complete filtration system in one.

With an easy to install, 6 input valve system and a clear port view to allow you to see the debris that is caught within, this filter is easy to use and maintain, regardless of installation location.

An economical option, the powerful filter minimizes water waste and helps save you money by using a low electrical input option.

This all natural sand pump offers six function valve control to allow the user to easily and efficiently filter, backwash and rinse, recirculate, drain and close the system.

There is a built in 24 hour timer and a strainer basket to easily remove waste from the filter, preventing the need for heavy maintenance as frequently as some other models.

The brand claims that the filter needs almost no maintenance, in fact, aside from the sand being replaced once every five years.

Also included is a pressure gauge so you can monitor things closely as the pump moves over 3,000 gallons per hour in its fast setting and almost 2,500 gallons in the slow cycle.

Engineered to provide an optimized flow cycle, this filter packs a powerful punch despite its small size.

Easily concealed among rocks and other pond decorations, the XtremepowerUS filter is a great option for small to midsize ponds.

The seven way valve gives the ability to filter, backwash, winter, re-circulate, closed, rinse and remove waste from the tank and creates an easy maintenance routine. Plus every single tank is tested and ensured to be 100% usable and of the XtremePowerUS standard.

You can rest easy knowing your pond filter will not fail when using these products. They’re tested to the max to provide the best possible result!

Available in both top and side mount sand filter options to assist in better blending the device with the surrounding pond decor, the Hayward filters are a fantastic option to maximize the aesthetic value of your pond without sacrificing functionality.

All models in the series are anti-corrosion coated and have self cleaning laterals to keep everything spotless and clump free.

Hayward guarantees even water distribution over every square inch of the sand, providing a thorough, deep clean unlike any other. As a complete tank, this is a solid piece that will work wonders in most pond set ups.

Suitable for water temperatures between 32 and 113 degrees fahrenheit, this product works well with all pond environments, as they should be kept between such range.

Hydraulically balanced laterals maximize the water flow and filtration, keeping your water clean by pumping it through high quality, clean sand.

The brand does recommend, as a precaution to keep the filter running at peak performance, to use only #20 Silica Sand or ZeoSand in the product to prevent clogging and potential poor filtration.   


Sand filters, though frequently overlooked and a bit controversial in the fishkeeping world, are a fantastic option for those with high quality water and a good bacterial cycle already established.

These are extremely low maintenance options and are great for the koi keeper on the go or those who want something a little easier than a traditional pump without sacrificing power and effectiveness.
