Quietest “Silent” Filter for Aquarium?

Topic:¬†NEED HELP: What’s the Quietest filter on the market for smaller tank setups?? Maybe 10 gallon tanks. The sound of it needs to be silent. For college kids that want to bring their fish to their dorm room!

Posted by Megan V: I went through the same problem with needing a silent filter. I had really good luck with the Aquaclear filters. They are still very powerful but keep quiet. They may be a little more noisy when you first start them up but it takes a week or two for some algae and muck to grow on all the internals and then they HUSH right up. They are also a top rated filter on the market

  • I have a little sponge filter powered by a quiet little air pump. The only thing you can hear is the bubbles, but it’s not loud at all, and you never have to worry about fixing squeaks or it breaking
  • I have betta duo tanks so they are quiet anyway but I used a sponge filter in my others.
  • I have the aqueon tanks too…when the filters is new it makes a little bit of noise but by day 2 it’s almost silent.
  • Why HASN’T anyone said internal filters?? They are inside the water and almost impossible to hear them. When something is submerged under water it’s very tough to hear it. I would think any HOB filter would be able to be heard because the motor is running on all of them.
  • The motors grow bacteria on them after a couple of weeks and it really helps make the motor more quiet because it’s almost like a slim coat on all the internal components.
  • I have a 2.5 gallon that came with a filter that is pretty much silent. Not sure if that helps!
  • Sponge filters, but changing filters can be problematic because the new filter won’t be cycled, run them tandem for a while.
  • Have you never transferred over media or squeezed out media right at the intake of the new filter before? Instant cycle.
  • Yes but I don’t believe it to be safe enough, my opinion.
  • Why? Its not the filter that holds the bacteria, its the media. So when you move the media from one filter to the next, the cycle is instant. I have transferred all the contents of a 55g into a brand new 220g. Since the media wouldnt fit as they were incompatible filters, i just squeezed out the sponges right at the intake and then added all the fish. Zero issues and I tested every hour for two days.
  • My comment was meant for if he chose to switch to a sponge filter, but otherwise I agree with just transferred media.
  • Ah, that makes sense. Although, to beat a dead horse, you can squeeze out the media inside the tank anywhere and it will work the same. Your water will just be super cloudy with detritus for a few hours is the only drawback.
  • New to this site. Love all of the videos. I have a few questions please..I have a 29 gallon tank..had a aqueon quiet flow 55/75 that I just replaced as I was thinking maybe an IF would be better? I got the National Geo IF40. How long until it gets established? I did transfer some bio filter pellets into it and in the top layer I put 2 small bags of activated carbon. How should I angle the nozzle for outflow? Mid tank? Bottom? Pic and Vid attached. Thanks
  • Green Nuphar japonica…a local aquarium guy’s offering this plant for decent price…Anybody has any experience or views on them in community planted tank? They were looking so damn good in his tank…these are the pics i googled up. Had no camera phone with me back when i visited him. He has some other exotic gorgeous looking plants too…they were quiet¬†expensive….Will visit him again with a camera & post the pics with names here. But i do wanna get this one…tips or suggestions?
  • …finally…my discus was doing good but had a light issue for couple of days now. my laziness got my discus…so, the lights were kind of off, the plants didn’t take in amonia-nitrates, had a bacteria grow, which got the discus..i can see one or two white patches on my discus…looking for a cure. so far, i think it’s Ich…will take pic as soon as i get my dad’s phone & post it here. I really love that fish, & it breaks me to see him all weak & hardly eating & just resting in the corner over the heater….

    Update after 9 hours :
    Umm, guys, i switched on my main lights of the room & discus started swimming around just fine. Couldn’t see any white patches. Switched back to the temporary low light on the tank &…i realised that i got tricked by the lights. Joey seems all good. it’s been over 4 days since the tank’s main lights got messed up. Have to run it on temporary low light i created for the box i keep my plants trimmings in, for now. i guess light does effect fishes. their colours are bit washed up. But when i added some more medium lights, the tank sprang back to healthy life. Discus’s swimming around, roaming around his usual spot in the front at the thermometer (Room’s pretty quiet & dark all the time, just me, sleeping in for the night & hanging around for a while in day time in between jobs)…the water change helped…So…Is it so? can lights effects behaviour of our fishes? i think so…was so upset all sunday because of this but got cheered up by this. Thank you a lot for jumping in with the solutions though. Will keep me ready to roll if i bump into those. Have a sweet & warm week ahead guys…Long live the discus.

Size Tank for Pleco? Aquarium Size

Topic: I have a 20 gallon aquarium that is a ‘high series’ tank. I have 3 molly fish and plan to get a Plecostomus. I’m wondering what size tank a Pleco needs? I know they get pretty big but can I just get one and maybe go with it? I know all of our tanks are crowded more or less so.. would it hurt to give a Pleco a nice home?

plecoEveryone puts these fish in small tanks and only the fish suffer. The Pleco can grow to 12 inches long very easily and live 20-30 years. Are you sure you know what your putting inside of your tank. I only advise beginner aquarists to put a Pleco in aquariums 50 gallons or larger. I would say to have your tank crowded like you speak of, you would have a small 30 gallon tank. The 20 gallon aquarium you have isn’t even worth calling a real fish aquarium.

You need to do yourself a favor and go out and buy a 55 gallon tank and go nuts with fish. You can buy one for super cheap and even cheaper if you buy used equipment. Even your mollies are cramped in a 20 gallon tank. If you catch Petco at the right time, they have a deal where 1 gallon of aquarium costs you $1. So a 55 gallon tank would only cost you $55 with tax. Even if you had to hold off on getting a stand and set it on a dresser for now.

But back to the Pleco, they get to be a very large fish and even reach in the 20 inch mark for length. That’s comparable to you as a human living inside of your bath tub… It’s just not right. I personally have a 75 gallon tank and feel like it’s too small. We all want bigger and better stuff haha. Hopefully that helps.

You could always buy a juvenile Pleco an put it in your tank while you plan for you upgraded tank. That would make a great reason to make you actually break down and go buy the tank. That’s how I did it and I guilt tripped my husband into needing a much larger tank because my fish were outgrowing their living space.

The juveniles grow more rapidly than what you would ever expect. Mine went from being tiny and the next I knew it.. I needed a new aquarium and was being pushed with time. Don’t let time sneak up on you too fast. Because like he also replied.. the fish is the one that suffers.

Worst comes to worst and you can’t afford a new tank and a fish outgrows your tank, what you do is bring it to the fish store and they will take it back and find a home for it. A lot of aquarists love this because they get free fish that are large in size. Otherwise large fish for tanks are somewhat expensive.
