This filter gurgles and sputters,it is not excessively noisy, but it is not quiet. I would say it is noisier than the Aqueon quiet flow 10. It does a good job filtering and the sterilizer has kept my tank Ich free.

Have not used the other devices you reference. The PF40-UV is not loud but definitively not what I would call quiet, especially when the strainer or tubes get a bit clogged or the skimmer doesn't work correctly.

I have no way of comparing it to other filters, since I don't have any of those. I can only say that these are relatively quiet. I have not found the noise to be an issue.

Sadly, no. I have a 3 gallon pico tank, and I thought this would kill my corals with the flow rate. But it has had the opposite effect. Also, you can choose the "direction" of the flow. Either through the bar, or there is a fan tip option. Wonderful system!

It is fairly quiet, it also depends on the load, if you run at 90% of rated capacity it will be louder than running at 40%. I have ran the generator through the night and it was not bothersome at all.

I ran mine in a 20 long and it worked fine for me. I have torch , acans , blastomusa , zoanthids , brain favia , leptastrea , daisy polyp corals with plenty of flow for them. I switched to a 30 gallon and I need 2 for that tank.

Quite a bit quieter than my old one. On the high setting you can still hear it, but I generally use the middle setting and it is much more efficient and WAY quieter. Remember you are getting about 80% of the flow for 50% of the electricity, and about half the noise.

It is fairly quiet. I have noticed a slight hum. I can also hear "boiling water" sound occasionally, when I have put too much salt in it. I have no trouble sleeping in the same room with it running.

I had this filter for a five gallon tank as a secondary filter. Mine started making noise as well, so I changed the filter. I did find that the lower it was in the wate::r the less noise it made. However the noise eventually got worse and became annoying, no matter what I tried! It may be better for 3 gallons or less. But I was dissatisfied with it. I hope this helps!

NO not at all, infact if I could I would have it sent back, you have to turn it on, walk away, far away, shut the door, wait a few minutes and it gets the pressure up, then it will quiet down a little. But fish tank hum, no way. ! Ear plugs needed for sensitive ears and no Talking! Don't want to discourage you, from buying because for the price it does a simple job, but not quiet at all.

I only use mine in ponds therefor they are very quiet. The vibration sounds like the problem though.

I run 4 hours in the am with a 3 hour nap and then on again for 4-5 hours. I also have a 40 gallon full of anubias. For such a small tank I would do, 3 on-3 nap and then 3 on

Not too loud. Kind of a growling hum if the water is shallow and a low moan if the pump is submersed. My cat sits over it and watches it sometimes, so not loud enough to scare a cat. Pump does the trick for me.

It is a whole shop compressor so it is loud, but surprisingly quiet for this type of compressor... I have another 80 Gal in my shop that is louder!

Yes. This unit actually may be too quiet; over the sound of the runnning water one has to concentrate to remember that it is on!

Hi Diana. On a scale of 1-10 where 10 is super loud---this drier is a 5. Not super quiet but also not super loud. It is a really good drier. It is very light and the air flow is very powerful.

I would say that the unit is fairly quiet. If anything, my fridge is louder than the RO unit. The only time you hear any noise is when the tank refills. Even then, it's just an occasional sound or two of the excess water draining down your pipes.

I had one in a 20L and thought it provided good flow for that size. I have also used it for a 10g QT tank as the only flow, it works well for that purpose as well. Depending on the amount of flow you need in the 20L and the amount of rocks / etc in there, you may need more flow than just one koralia 425.

It really depends on how much flow you're looking to put though the sump. I can say that I have one of these pumps for the return on my 90 gal. It's quiet and pushes a decent amount of flow over two 3/4 lines. Hope this helps.
