Customers say
Customers find the aquarium filter quiet and effective, particularly for 29-gallon tanks, with one mentioning it works well for a 55-gallon tank. The filter is easy to clean with a removable design, has plenty of space for media, and is easy to set up and maintain. While some customers consider it worth the price, others feel it’s overpriced.

Quiet and Amazing
8/19/2021: I’ve had this filter for a few months now for a 40-gallon and it’s doing a great job of keeping the water clean. I test the water every now and then and it’s doing great against nitrites and nitrates. The Seachem matrix combined with the sponge is doing a great job, and there’s extra room so I added a carbon pad. It’s also super convenient when it comes to cleaning. Maintenance is such a breeze with this. I clean the media basket once a week with a water change, and clean the impeller if the water in the filter basket looks dirty.The filter is extremely quiet. When I first started using it there was a buzz from the motor, but it gradually disappeared and now I cannot hear it unless I lean in. I had the same experience with the Seachem 35 so I’d say not to worry if the filter is a little noisy at first.This one has a waterfall sound when the water flowing out hits the aquarium water. Not super loud because there is a flat surface that breaks the speed of the water before it enters the aquarium. It’s just like a trickling kind of sound. I find this sound relaxing. I work from home and the aquarium is close by so I enjoy hearing it in the background. The Seachem 35 does not have the trickling sound, maybe because the water force is not strong enough to start with.I originally bought this as a backup to an Oasi canister filter, but now I realize I should never have gotten the canister filter. The canister filter was a nightmare to maintain. Weekly water changes were OK because Oasi makes it easy to clean the pre-filter, but further maintenance was such a pain. You have to clean the tubes with a super long brush and clean all the sponges in the canister. I usually did this with a bucket of filter water in the bathroom and usually it was a mess and a lot of hard work. Those days are so over. Listen, I took have watched a lot of Youtube videos of people taking about what a breeze it is to maintain a canister filter. Well, it’s not a breeze.One day I hope to upgrade to an 80 gallon, and if and when I do, I plan to get two of these going instead of a canister.I highly recommend this filter.

Excellent Design by Seachem
SEACHEM TIDAL 55 : The design of this filter is fantastic. Unlike all the HOB filters Iâve used in the past, the pump and impeller on the Seachem remains submerged in the tank allowing it to self prime. Just plug it in and it immediately begins to push water into the filter housing. This setup allows the pump to run at full speed continuously with flow adjustments that allow the user to control the rate water is released back into the tank from a trickle to full blast. Also, there is an adjust that allows you to use the filter as a full time skimmer or full time, down piped intake filter or any combination of both. That feature is very cool because normal skimmers included with other filters attach to the intake pipe and rarely pull enough water to work properly. Another feature is the pull out basket that holds the filter media. Just release a sturdy plastic lock and the entire basket pulls out. Allowing you to walk it to a sink or trash can to dispose of the dirty media and reload. No dripping water all over the house and no mess. They even include a universal heater clip and wire guides to attach your heater to the filter for a clutter free, compact tank setup. This filter is affordable, well built, runs silently and is completely serviceable including the pump and impeller. The Seachem design is a big step forward for HOB filters.Highly recommend.

Quiet, lots of media, smart design, easy cleaning, Fit my 20 gallon hexagon tank.
Pictures attached are 1 day after install.Tank: TopFin 20 gallon Hexagon(8.5 inch slot on back for filter was perfect for this one).Replaced: TopFin 20New Filter: Tidal 55Tank age: 1.5 yrs.Stocking: (max/ overstocked) shrimp,10 rasboras, 1 guppy, 3 khuli loaches, 4 Ottos, 88 bladder snails & ramshorn snails.Substrate: 2-3 inches aquasoil and corse sand.A Quiet Win for My Tank and My Wife! Seachem Tidal 55 was an easy replacement for the stock TopFin 20.I upgraded my barely over 1 yr old noisy Top Fin 20 HOB filter to the Seachem Tidal 55 for my 20-gallon hexagon tank, and itâs great! My wife loves the silenceâno more rattling to ruin our TV dramas. I canât even hear it from the couch! It cleared my tank up overnight, leaving the water crystal clear and my fish, shrimp, and snails visibly happier. The flow is adjustable (had to dial it down for my dumbo guppy), and thereâs about 30% more media spaceâI fit all my old media plus the bio-rocks it came with. Itâs the same width as the Top Fin 20, so it swapped in easily. Cleaning is a breeze and with the in-tank pump it self primes (less mess and power outage leave of mind). .A solid 5 stars so far for this efficient, quiet filterâmy tankâs looking great so far. And Iâll update this if it gives me any trouble. 05.06.2025

Great HOB filters except the skimmer.
I think these are great HOB filters.They last, they have great features such as the pull-out media basket, the pump in the tank so restart works without worrying about a dry filter, and the heater clip is a good idea.The only thing I donât like is the skimmer feature. I have a couple of these filters so I plug up the skimmer with aquarium silicone sealer as soon as I open the box. Problem solved.

Tidal 55, upgrade to 5 stars
After 24hrs the rattle resolved itself. Very nice filter……………..I have a Tidal 35 on a planted tank — no problem, it is quiet and works great. BUT, my new Tidal 55 has a rattle I can hear across the room.The key feature of these filters is they are quiet. Unfortunately, this one is noisy. Only one moving part (the impeller) and it rattles away even at lowest flow.No, it is not a rattling lid. I have kept fish for 40+ years, I’ve been around many pumps.The Tidal 35 is fine, but the Tidal 55 is disappointing. I like its many features, but the noise is unacceptable.

Silencioso, tiene buen espacio para material filtrante. Los materiales son de buena calidad, tengo con el ya casi un año y no ha fallado.

One of my local pet shops just replaced all of their AquaClear filters with these. So I decided to try out a 55 tidal just to see for myself.I’m running one Tidal 55, Aquaclear 50, and an Aquaclear 20, on my 75gal aquarium.Definitely a large improvement compared to the Aquaclear 50. A larger media compartment without larger outer dimensions. Greater water flow, and a lot quieter pump. The water outflow is lower in the tank too. Allowing you to have lower tank water levels. The intake is variable in length, and can be removed if you only want to surface skim.The filter primes every startup. Unlike the aquaclear filters. Which sometimes don’t prime, even when full of water.The motor was a little noisy when I first installed the filter. But has become completely silent after a week of operation. It measures in at 32db average. Whereas my aquaclear 50 measures at 43db.The black plastic blends in nicely with a black aquarium background. But the bright blue dials stand out in the tank. If they were also black in color, it would definitely look better.Another minor downside is that the surface skimmer cannot be fully disabled. It’s always drawing a little bit of water. This could be a problem if you have lots of duckweed. As the plant can be sucked into the filter, clogging the foam quickly.Overall, it seems to be the new top HOB filter. Same cost as an Aquaclear. With greater media capacity, quieter operation, greater water flow, and reliable self-priming.

Je suis vraiment satisfait!!!Ce filtreur mâa été fortement recommander et jâétait un peu nerveux à lâidée de lâacheter à la lecture des reviews sur le bruit du moteur, je me suis dit que dû à leur forte popularité la qualité nâétait plus celle du début mais loin de la!! Le moteur a fait un peu de bruit pour environ une semaine et maintenant plus aucun son. Si je nâentend pas la chute coulée jâai lâimpression quâil ne fonctionne pas. Le panier pour les média est spacieux et très facile pour la maintenance, le détail de pouvoir lâattacher dans le couvercle donne lâimpression que ça ne sert à rien mais câest réellement utile. Jâai enlever lâajustement du bas et boucher le trou avec une mousse noire car je ne voulais pas de bleu dans mon décor et ça fonctionne parfaitement. Je suis vraiment satisfait de mon achat et jâen achète un autre à coup sûr vu que mon bac a deux filtreur!!
