Aquarium Gravel Vacuums Compared: 4 Listings
As an Amazon Associate we earn from qualifying purchases.
This review compares four aquarium gravel vacuums and siphons from the source packet. The keyword sets two brands against each other, but the packet holds only one gravel siphon from the Tetra side and no gravel vacuum from the Aqueon side. The packet’s Aqueon item is an algae scraper, which is a different product type, so it is not ranked here. The four listings used here share one product type, and they state their tank sizes, flow rates and parts in different ways. The figures come from the packet dated 2026-10-20 and were not checked against live product pages.
Quick answer
The Tetra siphon is the only listing in the set that states a tank size of 55 gallons, and it is the only one whose bullets describe a 30 percent water change every 30 days. The minilake AGC01 states 80 GPH of adjustable flow and a tank range of 3 to 10 gallons. The Carefree Fish listing states a 3 to 8 gallon tank range and a 16-inch maximum working depth. The ECOSUB AQUA states 132 GPH in its title, the highest flow figure in the set, but it gives no tank range. For a large tank, the Tetra listing is the only one that states a size above 10 gallons.

Tetra Water Cleaner Gravel Siphon
The Tetra listing is a gravel siphon sized for aquariums up to 55 gallons. Its bullets describe moving the siphon through the gravel to lift debris and say it takes about 30 minutes to replace 30 percent of the water every 30 days. The package includes the gravel siphon, a priming bulb and a clip for the bucket. The highlight line repeats the 30 percent figure and adds that the product makes water changes easier.
The spec list gives a liquid volume of 55 gallons, a weight of 9.52 ounces, and dimensions of 5.5 x 3.38 x 13.75 inches. It lists the item form as a siphon, the pet type as fish, and the item type name as Water Treatment, which does not match the siphon form. The included components entry reads See label, and the warranty entry also reads See label, so neither can be checked from the listing data.

ECOSUB AQUA 132GPH Aquarium Gravel Cleaner
The ECOSUB AQUA title states 132 GPH, which is the highest flow figure among the four listings. Its bullets describe a four-function kit for gravel cleaning, water changes, debris removal and glass cleaning. The 6-foot flexible hose has a bucket clip, a flow control knob sets the water speed, and the unit needs no power because it works by hand pressure. The extension hard tubes adjust in length from 16 inches to 33 inches.
The listing says a built-in 3D filter net blocks small fish and gravel from being sucked out, and the suction head rotates 360 degrees. The spec list gives a weight of 1.2 pounds, a blue color, and a package size of 11 x 8.5 x 4.3 inches. It does not state a tank size range, so its suitability for a given tank has to be checked from the bullets and the product page.

minilake AGC01 Small Gravel Vacuum
The minilake listing is a manual siphon for 3 to 10 gallon tanks. Its bullets describe a flow control valve that gives up to 80 GPH, a thick silicone bulb of about 0.45 inches that starts the flow in two to five squeezes, and a 6.5-foot drain hose. The listing says the dual lock and clear tube help with observation, and that an anti-suction structure helps protect small fish and shrimp.
The spec list gives a flow rate of 1.33 gallons per minute, which matches the 80 GPH bullet (80 divided by 60 is 1.33). It lists a weight of 11.3 ounces, plastic and stainless steel materials, a black color, and a submersible style. The model number is AGC01, and the listing does not state a warranty.

Carefree Fish Small Gravel Vacuum Sand Cleaner
The Carefree Fish listing is a three-function siphon for tanks of 3 to 8 gallons. Its bullets give a maximum working depth of 16 inches and say it works with gravel particles up to 5 millimeters across. The package includes a wide gravel tube, a flow control valve, a hose fixture clamp and a 6-foot drain hose. The bullets describe a silicone squeeze bulb that is squeezed three to five times to start the flow.
The spec list gives a size of S (3 to 8 gallons), a weight of 7.7 ounces, a black color, and a warranty of one year from the manufacturer. The material entry reads Other, while the bullets describe ABS construction and a silicone bulb. The two entries describe the same parts in different terms, so the product page should be checked before buying.

How this review chose its products
The packet held twelve research listings and three extra listings for this keyword. Most of the research listings are aquarium kits, filters, water conditioners, test kits and decor, which are different product types. The Aqueon item is a magnetic algae scraper, which is also different, so the Aqueon side of the keyword has no gravel vacuum listing in this packet. The four gravel vacuums and siphons used here share one product type. The packet does not include a price or a rating for any listing, and this review does not add either. No unit was bought or used for this post.
Worked example: a 30 percent water change at each listed tank size
The Tetra listing says the siphon replaces 30 percent of the water every 30 days. For its top tank size of 55 gallons, 30 percent is 16.5 gallons per change. The minilake’s top tank size of 10 gallons gives a 30 percent change of 3 gallons, and the Carefree Fish top size of 8 gallons gives 2.4 gallons. These figures apply the 30 percent number to the stated tank sizes, so they show scale rather than a tested change time.
The flow figures show a similar spread. The ECOSUB AQUA states 132 GPH, and the minilake states 80 GPH, so the ECOSUB figure is 1.65 times the minilake figure (132 divided by 80). Neither figure is tied to a hose length or a bulb squeeze count in the listing, so the flow numbers cannot be turned into a tested drain time.
What the listings do not say
None of the four listings states a test of drain time, a noise level, or a tested water volume. The ECOSUB AQUA gives no tank size, and the Tetra listing gives no flow rate. The Tetra spec list says See label for its included components and warranty, so those items cannot be confirmed from the listing data. The Carefree Fish material entry reads Other, which does not match its bullet description.

The title states 132 GPH. The listing does not give a tank size range for that flow.
Does the minilake AGC01 match its flow figures?
Yes. Its bullet gives 80 GPH, and its spec list gives 1.33 gallons per minute. Those two figures are the same flow rate in different units.

Conclusion
Among the four gravel vacuums and siphons in this packet, the Tetra listing is the only one that states a tank size above 10 gallons, and the ECOSUB AQUA states the highest flow figure. The minilake and Carefree Fish listings are both built for small tanks, with stated ranges of 3 to 10 gallons and 3 to 8 gallons. Match the tool to the tank size you keep, and check the parts and warranty entries on the product page, since several of them are incomplete in the packet.
