Best Pond Filters for Maintaining Clean + Healthy Water

Best Pond Filters

Pond filters are important if you want to maintain a healthy water supply within your pond. These filters removed harmful chemicals that appear when the waste of fish begins to break down. When the waste from the fish starts to break down it releases toxins such as ammonia and nitrates.

It’s also crucial to have a pond filter to get rid of dirt and debris that could be dangerous to your healthy pond water.

What to Consider When Buying a Pond Filter

There are a few different factors that customers should consider when purchasing a pond filter. The first factor you must consider is how many gallons of water your pond holds. You want to make sure you’re getting the right size filter for the size of your pond.

Another factor you will need to consider is the amount of plants that are in your pond, since plants are beneficial in helping clean out the water. If your pond has at least 50 percent plant life, then you won’t need a UV sterilizer. You also have to think about whether you want a mechanical filter or biological filter.

The pump also comes with an impeller shaft that is made from polished aluminum oxide, which is non-corrosive. There’s no copper exposed which means it’s very safe for fish and it’s going to be more durable out in the elements.

There’s quite a few pros with the Simple Deluxe 400 GPH UL Listed Submersible Pump, with durability being a huge pro. Not only is the impeller shaft made from ceramic aluminum oxide, but the motor components also are encased in epoxy resin.

You’re able to place this pump either horizontally or vertically, depending on which works better for your needs.

One con about this product is that there are some components that are delicate and could break with little force. The flow adjuster is the biggest issue since it can easily break as you are trying to adjust the flow, even if you’re not using much pressure. Other issues people seem to have is that for some reason it just stops working after a period of time. It appears that within six-months of use, the pump just goes out without warning and without there being an obvious cause.
