Best Aquarium Sumps of 2020

Why do I need a sump for my fish tank?

In some cases, like a smaller Fish only or FOWLR set up, you don’t need a sump. However, if you have a tank that is going to have invertabrates/corals, or is going to be on the larger side, adding a sump to your set up is your best bet. Any time you have a protein skimmer (also needed for the invertabrates) or a reactor for nitrates or calcium, you will also need a sump. The sump will help to catch excess waste as well as provide storage for additional equipment/filtration.

Factors To Consider for an Aquarium Sump

Aquarium Set Up

Heaters come in various wattages, ranging anywhere from 10 W to 1,000 W, and in some cases even higher. A heater’s wattage is directly related to the size aquarium it is equipped to heat, so you’ll want to take the size of your aquarium into account when deciding which heater to purchase. It is recommended to use around 5 watts per gallon of water in your aquarium, but you may need more depending on how much you want to heat your aquarium.

Space for the Sump

Pending your aquarium set up, the next thing you’ll need to figure out is where your aquarium will live, and thus how much space you have for a sump. This may impact what type of stand you get for your aquarium as well. Understanding space available will allow you to narrow in on the best sump for your fish tank.

Your Budget

You’ll definitely want to consider your budget when deciding which heater to purchase for your tank. There can be a wide range of prices for heaters, so making sure you have a strict budget in mind will make your buying process simpler. Check out our list of top recommended heaters to see which one best fits your performance and budget needs.

Best Small Footprint Sump

Eshopps Cube Nano Refugium Sump


Pretty quiet and coming in a nice cube shape, this Eshopps sump really gets the job done. You will need a small protein skimmer to fit into this nano sump, but that’s the point of nano, right? It even has a refugium, although that is also a little small and you may need to modify the water flow to it a little in order to get a stronger flow. That said, this well built cube sump is highly recommended when you are working with a smaller space.

Trigger Systems Platinum Sump
Best High End Sump

Trigger Systems Platinum Sump

The crown jewel of the Trigger Systems Platinum Sump is the automatic filtration changing method. You heard that right, this sump will change the filters for you utilizing a fleece roll method, and a roll will last 4-6 months. That’s a lot of time and money saved changing filter socks. Tested up to a 3000 gph flow rate, there will also be plenty of flow for both the skimmer and refugium sections. An adjustable water level with a self adjusting top platform and laser engraved wall markings will help you keep a precise water level. Plus, the platinum comes with all the other bells and whistles like 4 dosing tubes, a moveable middle partition wall, and a magnetic sensor slider. You’ll spend the money for this sump, but it will hopefully save you both time and money in the long run as it keeps your aquarium’s water crystal clear.

Frequently Asked Questions about Aquarium Sumps

Why do I need a sump?

You need a sump when you want to add a protein skimmer, calcium and/or nitrate reactor, or other pumps to your system. You also need a sump if you have an open saltwater system. Sumps aren’t a must in your aquarium, but if you plan to house corals and/or invertebrates, you will likely want one. In a freshwater system, a sump can allow you to avoid the big, bulky canister filter.

What does a sump do for my aquarium?

Sumps will allow you to hold equipment as well as filter your water for a cleaner system.

How big of a sump do I need?

You should make sure before purchasing your sump that it is rated for the size of your aquarium, but a general rule of thumb is that the sump should be at least 20% of the size of your aquarium.
