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

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.

The SeaChem Large Aquarium Fish Tank Filter works great for my tank! It’s powerful enough to keep the water crystal clear and runs quietly without disturbing my fish. Installation was straightforward, and the filter media lasts a long time before needing replacement. My fish seem much happier with the improved water quality. Highly recommend if you want a reliable and effective filter for your aquarium!

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.

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 !!!
