Best Aquarium Cleaners of 2025

"I recently purchased the Aqueon Aquarium Algae Cleaning Magnets for my small glass tank, and I am absolutely thrilled with the results! The magnets are incredibly powerful, making algae removal a breeze. With just a few swipes, my tank glass is crystal clear, and I no longer have to struggle with stubborn algae spots. The design is intuitive and user-friendly, and I appreciate that this product is also suitable for acrylic tanks. Overall, these magnets have made tank maintenance so much easier and more efficient. I highly recommend this product!"

"I've been using this product for a few weeks now, and it does an excellent job at removing algae from my 40-gallon fish tank. I use it once a week to keep the glass clear and beautiful, allowing me to see my fish. The fact that it comes with two different types of cleaning pads is a great feature, as one is good for heavy residue and the other for light residue. I can see this product lasting a long time!"

"This cleaner works well for my 37-gallon fish tank. As a parent, I sometimes struggle to keep up with tank maintenance, but this product allows me to quickly remove algae from the glass. I notice that the algae doesn't come back as quickly as before, which is a huge time-saver. Definitely worth the money!"

"My fish tank always gets dirty, and this cleans it up in seconds. The quality is super great! It's perfect for 10-gallon tanks, and I love how easy it is to pump and use without any leakage."

"I have a 10-gallon tank and needed something inexpensive for cleaning. This little tank cleaner works great! The siphon creates a lot of suction, making it easy to clean the rocks and refresh the tank without adding it to my husband’s “honey do” list. It's a win/win for us!"

"This product works as expected; it sucks up water and debris quickly. I appreciate the long hose because it allows me to drain my tank directly into the sink without needing a bucket."

"I really appreciate the tough plastic handles and how well this cleaner works on algae. It's perfect for my tank!"

"This cleaning sponge is great! The thick handle makes it easy to use, and it's 15 inches long, which fits perfectly in my 20-gallon tanks."

"I switched from a magnetic algae cleaner to this one, and while it doesn't clean as effectively, I still manage to get two-thirds of my tank clean after a few tries."

"I use this on my saltwater tank. Best method is to spray, wipe, let dry a moment, then wipe again. Works as described and I’m not worrying about unwanted chemicals in my tank."

"I had low expectations, but I was shocked when I tried it on an old tank with tons of junk stuck to the glass. I sprayed it down and let it sit, and almost all of it came off! It's definitely the best I've used so far, and it's safe for the fish. I found it easiest to use during water changes when the water line is lower."

"I didn't think this would work since it's safe for fish and plants, but it does! To remove the hard water stains, I sprayed the product and used the rough side of a sponge. It took me about 5 minutes to get the stain out!"

"Overall, I find it works great! The multiple brass fittings made it easy to connect to my sink. I did have a minor issue with the connection point to the vacuum part blowing off once, but I managed to handle it quickly. Now, I just leave the end open when switching modes, which minimizes any spray effect. This product has really streamlined my water changes, and I highly recommend it—even if it's an off-brand. Just watch a few YouTube videos if you're new to water changers."

"I strictly use this for refilling my tank. While I find the suction a bit slow, it's easy to hook up to the sink with no leaks. It's a significant improvement over my previous methods."

"This product has been a life saver for me! I used to rely on buckets and the traditional suction method, but now I can clean my tank in half the time with less stress. I keep the adapter on my faucet so I can quickly attach the hose next time I use it. It's the perfect solution!"

"I found this product easy to use and it was effective in controlling algae without harming my fish. My tank looks so much better!"

"I regret not reading the small print. While it killed all my black algae and my fish were fine, my live plants are slowly dying. I'll be doing water changes to fix this."

"I’ve used this before and got it from my pet store. I was pleased to find a better deal here. It really controls algae and keeps the water clear."

"I purchased this based on the stellar reviews. Unfortunately, I was highly disappointed. The product feels flimsy, and the hose length is inadequate for my 55-gallon aquarium. I managed to clean only a small area before struggling to siphon water. I won’t be keeping it."

"As a first-time user, I found this product very easy to use. It made cleaning my new Betta's tank a breeze. I'm really enjoying it!"

"I never write reviews, but this cleaner is amazing! It effectively cleans the gravel and makes water changes super simple. I had to share my experience because it works so well!"

“I found that by placing the siphon straight down into the gravel, it cleans very well and quickly. Just watch your bucket, people! Lol. I’m very pleased with its performance.”

“Using the Laifoo 5ft Aquarium Siphon Vacuum Cleaner for the first time was a breeze! The priming bulb made starting the flow super easy, and it efficiently removed debris from my tank. The adjustable flow control is a great feature, ensuring that I can clean without disturbing my fish or plants.”

“I wish it came with a longer siphon tube for deeper tanks, but overall, this is the best siphoning equipment I’ve used. It effectively pulls up dirt while leaving the gravel intact. Great job on the design!”

"I found the product to be high quality and well priced. It really looks and feels like it will last a lifetime. Plus, it arrived ahead of schedule. I would definitely choose this company again!"

"The product isn’t anything fancy, but it seems well made. I just hope it lasts a while. I did notice that the handle could be longer, though."

"Honestly, just take a look at it. It's an excellent tank scrubber and taint scrubber. There's nothing worse than a dirty taint in need of scrubbing!"

"It works just fine. I have to say, I preferred my old Aqueon one; it felt much sturdier."

"I was surprised by how easy it was to use this tool! Unlike other siphoning cleaners I tried, this one didn’t make a mess at all. It worked flawlessly!"

"After trying multiple cleaners, I finally found a winner. The suction is controlled, allowing me to target the mess without draining my bucket too quickly. I'm really impressed with its performance!"

"I usually don’t write reviews, but this tool blew me away! In just 20 minutes, it transformed my tank. It’s efficient at removing debris from the gravel, and I couldn’t be happier!"
