8/15/2023 0 Comments Seachem filter 35![]() My biggest beef is that it is not shrimp or fry friendly. I love the overall design of the Seachem Tidal 35, but it does have some drawbacks. Always a bonus, especially if the tank is in a smaller room. Internal motors are also much quieter than external ones. I love this because you don’t have to fiddle with the filter a bunch to get it started again after a water change or if the power goes out. The pump is already in the water, so it immediately starts sucking in water and fills up the back for you. ![]() Meaning, you don’t have to fill the back of the filter with water to get the pump to start gaining suction. The thing I like the most is that it has an internal motor that rests inside the main part of the aquarium.įirst, it means you don’t have to prime this filter, ever. I love that you can mix and match media in this roomy space. There is a large compartment that can be filled with biomedia, mechanical and/or chemical media as you wish. The Seachem Tidal 35 is one of the best filters on the market in my experience. They do not require priming.Īn External motor is the reverse and may require priming after maintenance and/or power loss. Pro Tip: Hang-on-the-back filters with motors placed inside the tank are known as internal motors. So I avoid filters that use cartridges for the most part. It does not filter out ammonia or nitrite, so it doesn’t contribute to the nitrogen cycle.Īnd the carbon has to be changed out every 4-6 weeks, so any beneficial bacteria that have grown on the mechanical filter media on the outside gets thrown away when the cartridge is changed out. I also don’t think that the carbon itself is necessary in most established aquariums, so it’s just a wasteful expense. That’s it, no magic elves that come out at night and scour your tank clean. I’m not a big fan of filter cartridges and here’s why.įor the most part, a filter cartridge is just a plastic frame that holds some activated carbon sandwiched in between layers of mechanical filter media. Why I Don’t Really Like Filter Cartridges People use all sorts of things for biomedia, like sintered glass, unglazed ceramic or plastic balls covered in grooves. You need a lot more room than that for bacteria to grow on.īiomedia is made out of various kinds of porous materials that have lots of little nooks and crannies that greatly increase the surface area inside your filter, it’s like setting up a high rise apartment building for bacteria. Just a layer along the walls of your filter wouldn’t be nearly enough. ![]() You need millions and millions of bacteria to keep up with all the waste your fish produce. It’s the material in your filter that beneficial bacteria live and grow on. Biomediaīiomedia is an essential part of your filter, I would actually argue that it’s the most important part. Pro Tip: For a more in depth explanation of the nitrogen cycle, and how to get it going in your tank, please see this article. Nitrate is much less toxic and can be allowed to build up in between water changes.įilters are vital to aquariums because that is where the majority of the beneficial bacteria live, constantly pulling toxic compounds from the water and making them safe for fish. Nitrite is also very toxic, but that’s OK because another kind of bacteria almost instantly eats the nitrite and turns it into something called nitrate (NO 3-). One kind eats ammonia and turns it into nitrite (NO 2 -1). It’s carried out by several species of beneficial bacteria that live in our aquarium filters and break down harmful wastes. Luckily, we have the nitrogen cycle on our sides. Left to itself, the poop would just keep gathering, putting out more and more ammonia until the water became poisonous and killed all the fish. This is bad news since ammonia is highly toxic. As you can imagine, rotting fish poop gets pretty nasty. That waste builds up and starts to decompose. ![]() The nitrogen cycle is the natural process that breaks down fish waste in your tank and turns harmful, toxic materials into non-toxic ones.įish put off waste, urine and feces, into the water around them. What makes filters critical in fish keeping is that’s where most of the nitrogen cycle takes place, the key process that makes aquariums possible.
