These filters are top of the line. I have a 75 gallon tank with a Tidal 55 and a Tidal 75. The filters are virtually silent compared to most HOB filters. It glides effortlessly over the back and comes with an adjustable pin to ensure its level against many types of tank brands and sizes. The media capacity is like nothing else with plenty of room for multiple sponges and matrix to fit. It has an adjustable intake to virtually almost any level. For what you spend on this product you will get what you pay for. This blows tetra brand out if the water (no pun intended). The Tidals are reliable and long lasting products. The next step up would be canister filters in my opinion.

Powerful filter for my 29 gallon and quiet too! It has this low buzzing at higher levels but you can lower it so that goes away. The build could be better quality though, the emperor pro 450 which is my old filter has a thicker and stronger plastic and this one feels softer so it may not necessarily last as long. The durability in that way seems rather low and prone to scratching although I think that this piece is more function and customization over form, it is simple in a good way and not over-engineered. The size is excellent! Far smaller and fits the same needs in power to my old emperor pro 450, I highly recommend for a 29 gallon over the tidal 35 since it is adjustable. Ease of cleaning? This is the easiest filter to clean! It has a clip you push away and you can take the whole media basket out and click it into the filter top so water does not go everywhere when you are moving it to a bucket with tank water. Great filter! I highly recommend.

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.

My fish are happy. This is the first time I am using a Seachem filter for my 55 gallon aquarium and I am impressed by the quality. It was easy to set up, filter is adjustable and is running great. Best part is that it’s super quiet.

Took forever to get it and when it first arrived the filter looked like it was used. Really dirty, gross. Candy wrapper garbage in the box. The seller did offer to exchange it but I decided to try it. I don't enjoy returning things and I really don't have the time. The initial unboxing was disappointing but... I really like this filter so far. It has a large removable media basket. You can fit quite a bit in it. In mine I have the course sponge, matrix and ceramic rings, polyfil, and Purigen. The size of the media basket gives you the freedom to add whatever you choose for your aquarium needs. My water seems very clear and it seems to have quite a bit of power. We had the largest power outage in the history of my state last week and I didn't have to worry about being around to prime this filter. This filter primes on its own after power outages. My ONLY complaint is the skimmer. I have enough surface turbulence in my aquarium and I really don't need or want to use the skimmer. There is a knob to adjust how much you want to come in through the skimmer vs the intake pipe. But there's literally no difference at all. And if you have a planted tank like I do you would know why you don't want to use the skimmer. But that is really my only concern about the filter thus far. If your on the fence, try it. You won't be disappointed in the performance.

I've gone thru so many, so so so many, water filtration systems for my 40 gal. octagon tank. Seems like every other water change I have to replace the entire filtering system and was always struggling with getting it primed and water flowing. But SeaChem has changed all that! WOW! The self-priming actually works! And the water flow is controllable and fantastic! Very happy with this purchase.

About 5 months ago I decided to get back into tropical fish after almost 40 years. I still had the tank, but threw everything else out since so much time had passed I was sure everything was “new and improved “. I wasn’t wrong. I didn’t know what was good and what wasn’t so I relied on my LFS. I had a 20G but bought a 15G with a divider so I could have a couple bettas. My LFS sold me an Aquaclear 20 for the 20G and a Tidal 35 for the 15G. My 20G is a guppy tank with 15 guppies, a few nerite snails, and some cherry shrimp, so it’s not overloaded. My 2 bettas have a few nerite snails as well. I do 25 percent water changes every 4 days. The Aquaclear died after 2 months and I stupidly bought another one, but I wasn’t happy with the water clarity. I also have a sponge filter in the 20G. The water in my betta tank is crystal clear. The junk floating around in my 20G was driving me crazy, and I couldn’t believe the ditrius I was sucking up with my vacuum. These are guppies, not big fish! Then it occurred to me it might be the filter, so I replaced the Aquaclear 20 with a Tidal 55. Now, to be fair, the Tidal 55 is rated for a 55gallon tank and I’m using it in a 20G, but the Tidal 35 doesn’t have an intake tube, and my 20G is tall, so I opted for the Tidal 55 that does have an intake tube. Now my water in the 20G is crystal clear, just like my betta tank. No more stuff floating around in the water. It’s extremely easy to clean, it’s so quiet you don’t notice it at all. I live in the woods, no neighbors, no traffic, so I don’t have any “white noise” drowning out the filter noise. There really is no filter noise. The other nice thing about this filter is you can control the flow, so even though it’s a HOB, you can adjust it so you can have little or a lot of flow, which makes my bettas happy, since they like calm, still water. Another feature is a blue nob that pops up telling you it’s time to clean your filter, although regular water changes make this unnecessary. I’m getting ready to set up a 55G, and I bought a tidal 70 for that tank. I’m beginning to think that not only is the brand important, but the size as well. Going up a size can only help keep your water cleaner than with a lower power filter. I’m really happy with the Tidal filter, I won’t use another brand. I think my fish are happier too.

I purchased this pump thinking I will improve filtering in my kit tank, that the filter it came with, was not adequate for fish load and planted environment. Purchased this 55 gallon unit as way oversized with intention to run it at minimum flow in my 20 gallon. The idea of much larger media container was attractive and the smaller unit does not have long reach for tall tank. My confidence was also increased by all the amazing reviews and excited youtubers. Problem 1) As many other reviews stated. The media it comes with is not adequate and single sponge does not do enough mechanical filtering. No problem, there is plenty space to add more. The moment you add something more fine the filter starts bypassing the cartridge, since I have I have gotten larger unit than I needed and I calculated that to turn water around 10 times an hour I need to run the filter as low as 20%. This stopped bypass problem but created another ... Problem 2) The filter has 3 intakes ! you hear a lot about questionable skimmer but there is actually 3rd one under the pump motor itself. So now that I have to run the filter at 20% capacity in order to prevent overflow. I'm dividing suction power across 3 intakes. With my cloudy tank with particles flying everywhere after few days I noticed that I literally see stuff go right by bottom intake and not get sucked. I guess the top skimmer helped by gravity takes priority if the filter is turned down. What I had to do to improve situation. - Drill more holes in the white bottom media basket to allow more free flow into media container. - Removed the baby blue wheel all together and blocked that space with a piece of plastic to block mid point intake. - Blocked 90% of skimmer intake with a black piece of plastic cut out from food safe container. - Probably not needed for regular not tall tank, but I also took the intake tube from old cheapo pump and replaced the intake making much longer reach that has much better sized gaps distributed over larger area. As result I seen mechanical filtration clean up tank in literally 2 hours total. While I'm not an expert on hang on filters, I would most certainly not recommend this product that is raved to be top line unit, that is also priced at the very top.
