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

Very high quality filter, zero issues with it, nice flow rate that you can control for both output and suction, fit with adjustable knob so it doesn’t slack as it’s a hob filter, water crystal clear !

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.

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.

I've had this filter for over a year in a 95 gallon planted community tank, and overall it's been very good. It filters well and runs quietly most of the time. The self-priming feature is essential in my opinion as it starts right up after power outages and keeps it quiet. I like the media basket--it's roomy and cleaning is easy. At first I didn't think the surface skimmer was a big deal. I put a piece of thin foam over it to keep out fry/debris and it was usually fine. However, any time that a plant leaf gets stuck on it, it starts to make horrendously loud sucking noises. Right now, my water level is 1/4 inch below the black rim, and that is also too low for the skimmer--it sucks air and is SUPER loud and obnoxious. There needs to be an update to this filter to include a feature that shuts off the surface skimmer so that people with shrimp/fry/small fish/snails and plants can run this more effectively without the issues of things getting sucked up by the surface skimmer inlet. It's easy to pop a pre-filter sponge on the main intake, but the surface skimmer is a big deficit at least in my application.

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 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.

SUPER LOUD. The small tidals are tolerable, but the biggest 2, especially the 110 is crazy loud I keep returning it, hoping that they will send me a quiet mode., but it has to do with the design. I have cushioned everything, checked the impeller assembly, checked for loose parts..... NOTHING HELPS. THIS IS LOUD AF. DO NOT BUY.

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

Product is 110 volts only .. even though the box indicated 110 and 220. Factory refused replacement of motor and the motor is not available anywhere !!!
