SeaChem – Large Aquarium Fish Tank Filter, Tidal 110 Gallon (400 Liters) by Sicce

Best hang on the back out there. You get a Surface Skimmer, and plenty of room to put the included filtration and anything else you might wanna run (phosphate,nitrate, pads, ect). It’ll have your tank running great no problem.

Most aquarium filters aren't very good. My Tidals (I've had a pair of 110s since 8/20) are an exception, having won me over after my initial annoyance with a rattling noise in one, which I eventually fixed. Water flow is good, the self-priming feature is very welcome, and their reliability has been great. I use a pair of these filters on a 90-gallon planted, CO2-injected aquarium with five large angels, four young keyhole cichlids, five black neon tetras (great fish), seven emperor tetras, five corydoras, and three SAEs--so it's moderately stocked. I also run a pair of Aquarium Co-op's coarse sponge filters with two air pumps. I guess I like my symmetry! I like them better than my two Eheim 2217s. Yes, two again. The Eheims get rattly after about eight years, so I have to periodically replace the shafts and grommets. Canister filters are a PITA to maintain regularly. I've relegated them to my other tank, a 55-gallon with about 20 yellow lab cichlids (Labidochromis caeruleus). Obviously that tank is heavily stocked, but the Eheims and another sponge filter work fine in that setup. I like a lot of Seachem products, but I've found I don't really need anything any more besides Prime and Purigen, since I already have CO2 and my favorite fertilizers are pond tabs (cheap) for plant roots and NilocG for DIY water column fertilization for leaf feeders. Seachem's Tidal filters are a quality product, just like Prime and Purigen.

I trust Seachem for the quality of their products so when I first saw they had built an HOB filter, I had to acquire one (two actually). I’ve been keeping fish nearly 40 years, both Marine and Freshwater and used a number of different filters including several brands of canister filters. My favorite filter until this one was an Aqua Clear from Hagen (Fluval), because of the ease of maintenance and their versatility in what media can be used. My only complaint about the Aqua Clear units is that more recently, the quality of their internal parts has dipped a bit, particularly the motor shafts and impeller assembly with the result being very noisy filters. They continued to function, but were loud. With all of that said, I am impressed with the build quality, design and features of the new Tidal line of filters. I have 2 110’s running in a 60 gallon tank that is heavily populated with Convict Cichlids. Current media load is the Seachem sponge, double bags of matrix and chemi-pure with the second filter the same swapping the chemi-pure with Purigen. So far, so good - excellent flow, quiet operation and yes, crystal clear water. At this point, I’m extremely satisfied with these filters. As with all new items, reliability can only be determined through extended use. After 6 months, I’ll post an update regarding noise and function.

I have had my eye on this filter for a long time. I have a tidal 35 on a 20g tank and I like it a lot. I decided to add another filter to my 125g African cichlid tank. They are messy fish! I love this filter. Very nice design. Lots of room for media for a hang on back filter. Made of very sturdy material. No expensive cartridges to replace you basically put what ever you want in it. It does come with some bio media through not very much. Also comes with 1 piece of foam. I added extra foam, Seachem matrix and for now activated carbon to polish the water. It Moves a bunch of water for an HOB. I do have 2 gripes about it. This filter has a skimmer. So it sucks water from the bottom and the top. I wish they would design a way to close the skimmer. I don’t really need a skimmer I prefer to have the water sucked from lower in the tank. Also it’s not as quiet as I thought it would be. Not a deal breaker. It’s about as loud as the canister filters I run on the tank but since it hangs on top of the tank you can hear it more. The canister is inside the stand so it hides the hum. As long as you keep the water level high on the tank you can avoid the loud splash from the spillway. Other than that I am impressed with this filter. Seachem makes quality products and the pump is made by Sicce. They have a great reputation for pumps. Very strong filter! ******UPDATE****** I purchased another 110. This one is louder than the 1st filter. They need to redesign this filter. I think the motor would be quieter if they eliminated the skimmer feature or added a way to close it. The skimmer slots is where the noise comes from. You can hear the motor rattling.

I REALLY like this HOB filter! It is the best one I have ever owned. I am running it on my new 75 gallon aquarium. It currently has the foam and ceramic media that came with in it. I also put some polyester filter fiber, some additional ceramic media and a pack of Purigen. This filter has A TON of room for whatever media you want. I am using the Purigen to remove the tannins from the new driftwood. I am also using two large sponge filters with ceramic media in them, and finally a big canister filter. What is nice about this set up is that I can pretty much use the HOB for polishing the water and adjust that media as necessary. The three other filters can be primary bio filters. The only issue with these filters is with the packaging and the dust. Just like many other reviewers mentioned, the filter was covered in dust when I opened the package. That dust is from the bag of ceramic media that they include with this filter. The unfortunate thing about that ceramic media dust is that it acts like sandpaper. My filter looks like it has been sanded in several areas. It kind of ruins the aesthetics of the filter. It is not a deal breaker by any means. I just don't understand why SeaChem can't fix this problem. If it were up to me I would: 1) get better plastic bags that won't leak dust from the ceramic media OR 2) just don't include the ceramic media with the filter. It is annoying to get a brand new filter that looks like it is 20 years old. That being said, I love this thing! It's got good flow. It's quiet. I like that it's black and I don't have to look at dirty media. Oh, I almost forgot! The media tray lifts out AND the lid is made to carry it. Turn the lid upside down and set the media tray on the lid. The media tray clips on to the lid so you can transport the media and clean up without spilling water everywhere! What a great idea! I added a video of my Koi Betta and four more pics of the tank. Just look at that crystal clear water! This filter is really great!

I have it on my 120 gallon tank along with two biological filters run by powerheads. It does a good job of filtering. It's not as quiet though like I've repeatedly heard. It sounds about like the Aqua Clear except it doesn't have the vibrating from the lid like the Aqua Clears I've had did.

Great price bought the biggest tidal filter pumps 4 hundred gallons per hour Great big media basket to put what ever you want. Long tube that you can reach the bottom of your aquarium if you want to take all the stuff you dont want in your aquarium water my water is cleaner than ever does the work of my tidal 55 2 of them I had with small media baskets. And not noisy at all. To me they are one of the best hang on back filters there is .very happy with it thanks fisher60

Great idea but just doesn't work. I liked this filter a lot at first. Self priming is awesome feature. Filter seemed large and easy to service. But after a few weeks, reality. It is loud. If tank is not 100% full. Or if tank gets a bit low, filter gets loud, and something gets messed up and so it stays loud, even after you top off tank. Sad. Changing the filter media is a nightmare. Seems like you'd just remove the basket. But doing that dumps debris into the tank and makes a huge cloudy mess. And then you realize that you need to clean the whole filter anyway. Good grief. I contacted the manufacturer. They responded but kind of ran around the issues. Wanted a video, etc. Sent parts, but no difference. I had 3 of these, all the same problems. I took all 3 off and completely disassembled them, cleaning and carefully rebuilding. They were still loud. Then after a week or so, I had to clean the basket, which made a cloudy mess again, and realized this was just a bad design. Waaaay toooo much maintenance required, and still going to be loud and messy. I switched back to the emperor 450 and it is so much better. Not perfect either, but better than this thing. Maybe they'll learn from its issues and come up with improvements to make it easier to change filter without a mess, and make it not so sensitive to water level. I wanted to like it, but ended up throwing away 3 of them.

Ein Gerät kam anscheinend aus den USA und hatte einen amerikanischen Stromstecker. Als ich mir in einem Elektronikladen einen Adapter mit Euro-Norm kaufen wollte, wurde festgestellt, dass das Gerät nur auf 110 Volt ausgelegt war und somit in Deutschland mit 230 Voltstrom nicht verwendet werden kann. Ich habe das Gerät umgehend zurückgeschickt.

Buen producto justo lo que esperaba

This SeaChem filter is absolutely incredible! It runs quietly, efficiently, and reliably. I used to be a fan of Aquaclear but this self-priming filtration is awesome. When there's a power outage and the generator kicks in, so does the Seachem. I would highly recommend this product to anyone looking for a great filter. I run a 90 gallon aquarium with an eheim canister and this Seachem and have NEVER had an issue.

very effective, really good for medium aquarium.

Fantastic
