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.
Using it in a saltwater tank. Used Fluval C4 and Aquaclear in freshwater tanks but had issues with the C4 after a year and the Aquaclear plastic is really cheap. This filter is silent. If started out with a little noise but then went super quiet. I love the media basket and the leveling screw. The wire loop is great as well. I didn't like the heater holder so I took it off. And the self priming is so nice after using the other filters that didn't have this function. My only complaint is that the dial inside of the tank is bright blue. So I have a black background that my wavemaker blend into and then this blue wheel that stands out. Other than that it is a great filter.
I love this filter because you can put a lot of media of your choice in it. For beneficial bacteria, carbon extra sponges whatever your preference is. Can adjust the water flow. It's quite, can here a small waterfall but not annoying. has a skimmer you can turn on or off. Primes automatically. That is important for me during power outages if I'm not home I know my filter will run and not burn out like others that won't prime without adding water back in the filter. Would definitely buy again!
I had an Aqua Clear20 on my 10 gal. half moon tank and it worked great at keeping the water totally clear but after a couple of power outages, I knew I needed something else. The pump on it does not prime by itself so no restart. Luckily I was home the first time but the second time the power went out, I was on a weekend excursion in the mountains and when I came home, the fish tank was murky and the water was unfiltered cause the pump didn't restart for 2 days. So I ordered the Tidal 55. Its a bit of overkill for a 10 gal. tank but I didn't like that the Tidal 35 didn't have a down tube for the intake. I had to modify the opening on the tank cover and along the back framework of the tank cause the opening was just 6 inches and this new HOB is 8 inches in width. Not a big deal as you can see in the pictures, its a perfect fit now. I love everything about this Tidal 55. Lots of room for your media, runs absolutely quiet, set the surface skimmer at low and set the water flow at low and perfect. The pump started right away when I plugged it in so hopefully I won't have to worry when the next power outage occurs. Highly recommend it.
I have been a long-time fan of AquaClear HOB filters for about the last 25 years, and still am. However, I have two tanks currently running that needed a filter with a lower "waterfall" spout (where the water flows out of the filter into the tank). The ACs have very short spouts on their smaller models, and the evaporation on these particular tanks would cause the filter to create a lot of waterfall noise within a day or two because they didn't hang low enough into the tank. So, a year ago I tried a Cascade HOB, which was great until it totally died at the 1-year mark. Needing a new option, I set out to see if there was something else that fit my requirements - a low-hanging water outtake, adjustable flow, and super quiet at around the same price point as an AquaClear. I saw some great reviews on this Seachem filter and went with this model for my 33gal simply because it has the intake tube, which the smaller filter doesn't have and seemed odd to me. It's been running for a few days and over all, I'm very please with it. It is EXTREMELY quiet. It hangs low enough into the tank that I don't have to top it up every day to keep the water noise at a minimum. It is self-priming which is an AWESOME feature. It has a fantastic large media basket which makes it super easy to customize it as you need. I love that it's black, it basically disappears in the tank against my black background, though the dial that adjusts between the skimmer and intake flow is blue, so it kind of stands out like a sore thumb. My only complaint, and the reason I am giving it 4 stars, is that it has a minimum water level requirement on it that is only a few inches from the surface of the water, I assume for the skimmer function. Other HOB filters that I've used basically will operate as long as you keep the water level above the intake, so I've been able to do my weekly 50% water changes without having to shut the filter off or having it stop because of a low water level. This filter doesn't allow for that, so I had to unplug it to do my water change. It's not a HUGE deal, though a minor pain, because the filter is new and self-priming, so it starts up instantly again. I will have to see how this holds up over time - I know after years of use, the AC filters can start getting a bit hit-and-miss about starting up when plugged in if you have to shut them off, so I'm not sure if this Seachem filter will do the same after years of use.
I have been using other Seachem products but this is my first experience with their filters. As others have mentioned the lid doubles as a drip tray which makes this filter so easy to maintain. Comes with a course sponge and a bag of Matrix. There is plenty of room for additional media, I have added Purigen and a finer sponge as well and the water is absolutely crystal clear. I have fish that are sensitive to excessive water flow and it is so easy to adjust on this filter. The tank is in my daughters room and it is extremely quiet. Overall an excellent first impression.
Some comments compare this filter to the aquaclear 50.. I have both. In terms of water level, Seachem needs higher water line than the aquaclear otherwise, there is an awful suctionning noise. For the power of the filter system, the Seachem definitely beats the aquaclear. The real issue with the seachem comes from the filtering media coming with the filter.. the sponge is basically see trought and the worst to filter small particules out of the water.. Add some sponge media for sure otherwise it does an awful job at keeping the water clear... once this is changed, the Seachem beats the aquaclear 100% for keeping the water clear... first pic is the aquaclear 50 in a 20 gallon, 2nd is the seachem 55 with new filter media in a 40 gallons.. (the aquaclear was not powerfull enought for my 40 gallon so i put it in a 20 gallon)
I have been in the fish-keeping hobby for over 25 years. I also spent time working in the the tropical fish business, and even running a fish store for a few years. I have seen filter technology change (somewhat) over the decades, but this one is a game changer. The surface skimmer feature works exactly as advertised. My tank went from an opaque layer of protein on the surface, to crystal clear. The filter is exceptionally quiet, as well. I am going to ditch my noisy, unreliable and hard to clean Eheim canister for a second one of these.
En remplacement du Fluval Aquaclear 50. Aquarium planté. Belle amélioration notamment pour la chute d'eau et ses réglages, son ecumoir de surface, sa facilité d'entretien, son fonctionnement silencieux (après une semaine). Attention cependant, le Tidal 55 est plus gros et encombrant que l'Aquaclear 50. Matrix est inclus et pour le prix, Seachem pourrait également y ajouter Matrix Carbon et pourquoi pas Purigen. Recommandé sans hésitation.
Best HOB ever! I am switching all my existing Aqueon to Tidal. It is a great value filter. The filter compartment is odd shaped but big enough to fit most of the media. Motor is quiet and auto start is a bonus. It is bit ugly with the blue on it but doesn't bother me. Make sure to only use this for 60% of rated capacity. Like for 40g, use 75g model rather than 55g.
