SeaChem – Large Aquarium Fish Tank Filter, Tidal 75 Gallon (300 Liters) by Sicce

I have a 35gallon tank that is filled with platys gone wild. What started out with five exploded to at least fifty. So pulled out all the plants and bought the oversized SeaChem 75 to handle the biological load. I considered a canister filter but I wanted something simple to maintain and more or less leak proof. This filter checks all those boxes. It is fairly quiet and the only noise I notice is the babbling water. My vibrating air pump masks the rest. I also like the fact that there aren't any hoses snaking inside and outside the tank. The filter does a good job filtering the water. It is clear and I rarely see any fish waste. Customizing the filter media is simple. The only quibble I have is the flow control. For example it would nice to have a way to cut off all flow to the surface skimmer. In comparison to the canister filter I was considering, this filter is 1/3 the price for good performance without the headaches. After a month, I'm happy with my decision.

Love this filter. For the most part it is super quiet. As you can see in the videos. But you must have the water at a specific level with the filter. If water evaporates a little bit it will make a little bit more noise. And I’ve noticed you do have to play with the water flow a little to get that quietness. I personally don’t care what it sounds like as it’s in my living room and this filter is the best bang for its buck. I got the 75g filter for my 40 gallon as I want to stock it pretty good and need as much filter capacity. Which you can see the compartment in the filter is huge. I managed to fit my old filter media in there to start up my cycle a little faster. What’s also nice is that the motor is on the inside of the tank. So you don’t have to prime it after every water change. And if the power goes out. That’s one of the main reasons I picked this over aquaclear or the likes. And I do love that it’s a surface skimmer(when the water is at the right level) especially for the fish I plan to keep in there, they don’t like a lot of water movement. I think the quality is fantastic. Comes with media. You will want to get filter floss and just cut it to the cartridge size just to trap any particles. For reference it’s the green stuff in the picture. And you will probably want an intake sponge if you want to keep shrimp. Because this does not come with one and the holes are pretty big on it.

I had another brand HOB filter that uses filter cartridges. I tried to reuse them, but they're too fragile and would practically fall apart cleaning and the filter would stop up quickly. I then started looking and found this Seachem Tidal 75 HOB filter, there we're high praises for this being one of the best of the HOB style filters. This filter is easy to service. The filter has a filter basket. To do media changeovers, you unlock the filter basket by pulling the blue lock button towards the front and lift basket out. The lid has a detail on the bottom side to snap the bottom of the basket to the lid to keep from dribbling water on the floor as you carry it to a sink to setvice the sponge and bio-media. The sponge and Seachem Matrix comes included. I added some sintered ceramic rings into the zippered mesh bag (included) to fill the bag and have bio-media bag on top of the sponge inside the basket. Your options are endless in regards to filter media. I plan on using Purigen or something similar later to crystalize the water and make appear like there's no water. The water is pumped by a pump on the intake submersed below the waterline, so it never needs priming, power outage, no worries because it will start back up immediately when the power comes back. The Tidal 75 has 2 intakes, the intake tube on the bottom and the skimmer. Then it has a intake control valve that controls the flow between the 2. I have the most of my intake coming from the intake tube on the bottom and the least amount of flow possible on the skimmer intake. It has a flow control on the outake to control how fast water is pumping through. All the way down will slow the flow to a trickle, all the way up gives you 350 g/h. I have mine on a 40 gallon and it is working extremely well. It is very quiet. I highly recommend the Seachem Tidal HOB filter. I have absolutely no regrets, excellent filter for the price point.

Filter worked intermittently. Works for a minute, stops for 3/4 minutes, then works for a minute or so again before stopping for 3/4 minutes. Returned. Not worth the hype. Stick to Eheim/Aquael.

Excelente filtro.

He probado 3 marcas de filtros de este tipo y por lejos este es el mejor, es silencioso, tiene muchísimo espacio para materiales filtrantes, ya viene con buena cantidad de Matrix, los materiales de fabricación se perciben resistentes y de buena calidad, su funcionamiento y mantenimiento es sumamente sencillo, han pensado en muchos detalles en su diseño, el skimmer de superficie funciona bien, pero si el nivel de agua está muy alto le cuesta atrapar las partículas, se puede regular el caudal hasta dejarlo casi en cero. El único detalle que le veo es que cuesta un poco sacar la tapa donde está la bomba, esa pieza es un poco ancha y se tiene que apretar y jalar al mismo tiempo, fuera de eso lo recomiendo ampliamente si buscas un filtro de este tipo.

Model: Seachem Tidal 75 Filter media: Coarse sponge (included), Fluval Biomax (separate purchase), Seachem Purigen + media bag (separate purchases), and Seachem matrix (included) Tank size: 60 gal 48"l x 12"d x 24"h Stocking: Red cherry shrimps, neon tetras, bamboo shrimp, rams horn and trumpet snails The Tidal 75 is a powerful filter with many conveniences that make it superior to other brands and models. Removable media basket is such a great design. Flow control works really well. At max flow intake, my media restricts the flow too much and the water level rises a bit too high in the filter - so I keep the flow in the middle range. Also at max flow, I found it to be too turbulent for my little shrimps and fish, and some waste and sand was being kicked up from the substrate. I don't find the filter noisy. The only noise I notice is any splashing caused by having the flow too high, or any air that gets trapped in the basket when starting the filter dry (the trapped air clears itself over time). The impeller is located inside the tank which also dampens any noise. Note to tanks with shrimp or fry - this filter will suck up smaller organisms and kill them. I was not careful initially and did a sloppy job with securing mesh to the filter and lost about 10 shrimp who found their way into the filter, including a berried momma. I have since redone this with sponge and filter floss instead of mesh as outlined below: 1. end of the tube (don't forget to cover the hole at the very bottom) 2. on the cover below the impeller - remove the cover and put a sponge over the grille on the inside of the cover 3. surface skimmer intake - remove the impeller and use a kebab skewer to push filter floss into the gap to cover the grille

The Seachem HOB filters are excellent. They are quiet, have flow control, water intake control, a motor that's in the water which means it is self-priming and will restart if the power goes out, and they are very customizable in terms of media. You can customize the media just like a cannister filter, but they are much easier to clean than a cannister filter. I have a 110 and a 55 on my 55 gallon tank and they keep the water crystal clear.
