Aqueon vs Koller Products Aquariums: Side-by-Side

This comparison sets an Aqueon glass tank against two Koller Products plastic kits and three replacement cartridge listings made for Koller filters. The two research listings were checked on 12 October 2026, and the other four were checked on 18 October 2026. Every figure is what the listing states on the day it was checked. Where the title, bullets and spec table disagree, both values appear side by side.

The Aqueon listing is a tank only, and the Koller kits include a filter and light. Read the included parts before you compare prices on the Amazon pages, because the two brands sell different sets.

Quick answer: which tank to look at first

If you want a glass rectangle with a center-braced frame, the Aqueon 20 gallon long is the only glass tank in this set. Its listing gives a tank volume of 20 gallons and a product size of 30.25 x 12.5 x 12.63 inches. If you want a complete kit with a filter and light, both Koller listings are plastic kits. The 3 gallon 360 kit is the smaller of the two, and the 6 gallon AquaView 360 kit has a built-in light timer and a 45 gallon per hour filter.

1. Aqueon Glass 20 Gallon Long Tank

The listing describes a glass tank for freshwater and marine aquariums with clean silicone edges and a black trim. The spec table gives the tank volume as 20 gallons, the material as glass, the product dimensions as 30.25 x 12.5 x 12.63 inches, and the item weight as 24.6 pounds. It gives a limited 5 year warranty and the model number 100552739.

The bullets say the larger sizes have reinforced center-braced frames to prevent glass bowing, and they list 20 gallon high, 20 gallon long and 29 gallon options. One bullet gives a second set of dimensions, 34.0 x 16.2 x 17.0 inches with a net weight of 27.0 pounds, which does not match the spec table. The included components field names only the tank, so the listing does not include a filter, a light or a hood.

2. Koller Products 3-Gallon 360 Aquarium with LED Lighting and Power Filter

This is a clear plastic cylinder kit. The spec table gives 3 gallons, a product size of 9.5 x 9.5 x 13 inches and an item weight of 2.5 pounds. The shape is listed as cylindrical and the specific uses include betta fish, fancy guppies, ornamental shrimp and tropical fish. The bullets describe LED lighting with 7 color choices, from daylight white to red, and a power filter rated at 25 gallons per hour.

The bullets give a second size, 10.25 inches in diameter and 14.75 inches high, which does not match the 9.5 by 13 inch spec table. The filter bullet names Koller XS replacement cartridges, so the cartridge listings below are the ones that fit this kit. The listing describes the plastic as impact resistant and says it does not leak, which is the seller’s own statement.

3. Koller Products Plastic 6-Gallon AquaView 360 Aquarium Kit

This kit is the largest Koller set in the comparison. The title gives 6 gallons and a clear plastic tank, and the set name is an aquarium starter kit with four pieces. The spec table gives a diameter of 11.5 inches and a height of 19.5 inches, a model number of AP360-6FFP and a one year manufacturer warranty.

The bullets describe LED lighting with the same 7 colors as the 3 gallon kit. The built-in light timer can run the light for 4 hours, 8 hours or continuously. The internal power filter is rated at 45 gallons per hour, and the bullets name Koller S replacement cartridges as its filter media. The age range is listed as all life stages.

4. Small Replacement Cartridges, 12-Pack (SW Products)

This listing is a 12-pack of small cartridges with a three-layer design: a cotton layer for large particles, an activated carbon layer, and a final cotton layer. The spec table gives the brand as SW Products, the model as SWP10FC-120, the size as small and the item weight as 4.8 ounces. The bullets say the cartridge fits Koller Products 3, 5 and 6 gallon tanks.

The bullets say to replace each cartridge every 3 to 4 weeks, and they say the cartridge needs no assembly beyond a rinse in cold water.

5. Small Replacement Cartridges, 6-Pack (FKBYM)

This 6-pack is listed under the brand FKBYM with the model AQ10FC-60. The spec table gives an item weight of 2.46 ounces and a package size of 6.3 x 4.09 x 1.18 inches. The bullets say it fits Koller tanks of 4 to 10 gallons and a betta filter kit. The listing describes a dual-layer microfiber cotton with coconut shell activated carbon, and it says each cartridge lasts 3 to 4 weeks.

The same listing then says the 6-pack can be used for about 8 months in total. That figure does not match the per-cartridge interval, as the worked example below shows.

6. Koller Products Small Replacement Filter Cartridges, 6-Pack (SW Products)

This 6-pack carries the Koller Products name in its title and is listed for Koller Products aquarium kits with power filters. The spec table gives the brand as SW Products, the size as small and the item weight as 2.39 ounces. The bullets say the cartridge suits 3 to 10 gallon aquariums, and a separate bullet says it fits Koller power filters for 4.5 to 7 gallon tanks.

The bullets say the cartridges come ready to use, that a rinse with water removes surface dust, and that each should be replaced every 3 to 4 weeks. The bullets also note that the product may ship in white packaging depending on region.

How we chose these six

We kept the Aqueon tank and both Koller kits because each lists a tank volume and a size. We kept the three cartridge listings because each names a Koller tank or Koller filter in its title or bullets. The cartridge brand fields name SW Products or FKBYM rather than Koller Products, so they are listed as compatible items.

  • Volume or size: each tank states a volume or a dimension in the spec table.
  • Koller fit: each cartridge names a Koller tank size in the bullets.
  • Stated interval: each cartridge listing gives a replacement period.

Worked example: cartridge life against the stated interval

The FKBYM listing says each cartridge lasts 3 to 4 weeks, and it has six cartridges. Six cartridges at 3 weeks each give 18 weeks, and at 4 weeks each they give 24 weeks. That is about 4.1 to 5.5 months, since a month is about 4.3 weeks. The same listing says the pack can be used for about 8 months in total. The two figures differ by roughly 2.5 to 4 months, so the listing does not agree with itself.

The tank sizes give a second comparison. The Aqueon listing gives a footprint of 30.25 x 12.5 inches, which is 378.1 square inches of floor. The Koller 6 gallon kit has an 11.5 inch diameter, which is about 103.9 square inches of floor. The Aqueon footprint is about 3.6 times the Koller footprint, while the Aqueon volume is 20 gallons against the Koller 6 gallons.

What the listings do not say

  • None of the listings compares the Koller kit with the Aqueon tank on water clarity or fish health.
  • The Aqueon listing gives no light, filter or hood, and the spec table does not name a stand.
  • None of the three cartridge listings gives a cartridge capacity in gallons or liters.
  • The listings do not state whether the Koller cartridges are made by Koller Products or by a third party.
  • No listing gives a water temperature range for the Koller kits.

Frequently asked questions

Which Koller kit has a light timer?

The 6 gallon AquaView 360 kit. Its bullets say the light can run for 4 hours, 8 hours or continuously. The 3 gallon kit lists LED lighting with 7 colors, but its bullets do not name a timer.

Which cartridge fits a 6 gallon Koller tank?

The SW Products 12-pack lists Koller 3, 5 and 6 gallon tanks. The FKBYM 6-pack lists 4 to 10 gallon Koller tanks. The SW Products 6-pack lists 4.5 to 7 gallon Koller tanks.

How often should the cartridges be replaced?

All three cartridge listings say every 3 to 4 weeks. The FKBYM listing also gives a total of about 8 months for its 6-pack, which does not match the per-cartridge interval.

Does the Aqueon 20 gallon tank come with a filter?

No. The included components field names only the tank. The listing does not show a filter, a light or a hood.

Are the two brands the same size?

No. The Aqueon 20 gallon tank is 30.25 inches long and 12.5 inches wide. The Koller 6 gallon kit is 11.5 inches in diameter and 19.5 inches high. The Koller 3 gallon kit is listed at 9.5 by 9.5 inches with a 13 inch height.

Conclusion

For a glass tank with a stated volume of 20 gallons, the Aqueon listing is the only glass choice here, and it is a tank only. For a plastic kit with a light and a filter, the Koller 6 gallon AquaView 360 is the fuller set, and its light timer is the feature the other listings do not name. The cartridge listings only fit Koller filters, so check the tank size against the fit range before you buy.
