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.

It might be a little loud but not enough to bother me. Awesome design and easy to clean. It has a ton of room for whatever media you choose. It’s powerful and I’m glad the flow can be adjusted.

This filter has handled my 75 gallon with ease. They are leak value for my money is perfect. Quality is spot on, noise level is non existent it’s also scratch resistant and looks nice on the back of my tank.

I bought the Tidal 75 unit from Amazon about a month ago. I was very excited to try it on my 55-gallon tank that houses mostly platies and black neon tetras.As far as HOB power filters go, this thing is feature rich. There are two adjustable flow controls. The first blends in or turns off flow through the intake, which in the off position leaves only the skimmer operational (more on this later). The other adjusts the flow from the pump itself, slowing total water flow through the unit by 80%.Personally I leave the intake wide open all the time and turn the flow down to a small trickle during feedings. The intake screen has large openings that could easily suck up fry. I may suggest an intake pre-filter for breeder use.The pump is powerful, and below the water line so priming is totally a non-issue. The filter never needs to be primed!The lid has a small bobbin that supposedly pops up when the mechanical filter sponge is full. I have serviced this filter twice and, while I may clean my filters more often than I need to, I have yet to see that bobbin move. I believe when that bobbin pops up, it will be beyond time to perform filter maintenance.Underneath the lid is a cavernous media basket that easily unsnaps from the housing. If you flip the lid over there is a secure way to interlock the basket and lid together. This provides a drip-free tray to carry to the sink. Excellent feature.The basket holds what must be 1.5 litres of media. It came with a sponge for mechanical filtering, and a large mesh bag filled with a smaller amount of Seachem Matrix bio rocks. I put a pound of Fluval ceramic rings in with the included Matrix media and still have room for a decent sized bag of activated carbon if needed.I replaced a Marineland Penguin 150 for the Tidal. And even though it was only rated up to 30 gallons, the Marineland was far more effective at biological filtration; likely due to the infamous bio-wheel. The Tidal filters only have provisions for submerged media, which IMO is less effective as bacteria need oxygen as well. I did manage to rig the old bio-wheel to this unit, and would recommend this modification to anyone who has a Tidal filter.The skimmer is powerful! Let's not even talk about protein film, it is non-existent. It pulled out every bit of duckweed that I was on-the-fence about. Any leaves or floating bit of whatever WILL be removed by the skimmer. Half of the skimmer weir is below my water line, which I often fear a wandering fry will fall into it. Generally they don't go near it but when they do they are strong enough to swim away from it. I did, however have my first battle with ich right after I got this unit. I had one fish fatality and the skimmer pulled the little guy right up to it.There is a place on the side of the housing to clip a heater to, but I don't care to have my heater set vertically. Luckily the clip is removable.Pros--Never needs primed-Extra-large media basket-Adjustable flow controls-A functional skimmerCons--Bio media is submerged, I like bio-wheels!-Skimmer is almost too effective. Very small fry are at risk.-Intake screen has large openings. Also a danger to fry-Throws a lot of debris after servicing the media basket. Only way to combat this is to remove the whole unit and rinse before putting back into service. Not cool.

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.

The media could not be loaded.

Model: Seachem Tidal 75Filter 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"hStocking: Red cherry shrimps, neon tetras, bamboo shrimp, rams horn and trumpet snailsThe 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 cover3. 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.

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.
