I have a fluval 406 for a turtle tank (65 gal) and the last time I cleaned it, when I started it back up it started making bubbling hissing noises. We have checked all parts and they are on correctly. Any one have any idea how to fix it. The turtle is...

My thought would be it's getting air either on the inlet or outlet tube where it goes into your turtle tank. Or the seal where the red handle is on top is going bad

the one we got, has some problems too. all these tanks seem to have different issues. You might want to send it back if you can for a refund.

Mine wasn't seated good and was letting a small amount of water leak into the bowl. Once it's gets low on the float you hear the tank filling back up. That's the only way I would think of it alarming you.

Their are no direction that I find. I have a 90 glass tank I just got it yesterday and put one cup in my fluval 406. I checked it this morning and ready was the same as it was before I added it to the fluval about 7.0. I'm going to check it tonight and see if it dropped. I can only assume that it works slowly. I a tank your size I would but 2 cups in and check it everyday and when it reaches your goal on remove a cup a store for latter use. O e would think k that fluval would give you some gauge as to how much to use put they don't. Be sure you monitor because if it drops to low or to fast in can kill fish. I'm testing every day but I'm pretty sure it works very slowly. Hope I helped you out. Their are no direction that I find.

Sounds like something might be wrong with the pump, or the dial. Mine is completely adjustable all the way down to almost no bubbling at all. I would call customer service and see what they have to say. Good luck!

It happened with mine when there was too much salt in the water and when the hard water deposits started to build up around the coils. If you soak it in vinegar that should help to break up the deposits and stop the bubbling

You need to fill up your water tank once again when you see the "F" show up. Don't forget to add the bacteriostatic agent so you don't grow any mold. Good luck. I love my humidifier and it is wonderful to have a much moister environment. Arlene.

I have had mine for 3 years and works fine. Mine is in a 40 gal aquarium! Takes up some tank space, but mostly hangs outside. Noise is moderate but expected. You need to keep adjusting the air to keep tank bubbles down, as with all brands.

In addition to what Jason said, filters bubble and fish jump, even the little ones. So to keep from "decorating" the outside of your tank with watermarks and dead fish, put a lid on it:)

I have experienced the same problem. Make sure you have a high water level and a tight seal in the skimmer basket.Ed

Yes I had the same problem and ditched it and found a better humidifier. Our unit leaked from the very same spot. Other people have had the problem. We've had this one for about 6 months: Crane Drop Shape Ultrasonic Cool Mist Humidifier with 2.3 Gallon output per day and it seems to be working well. No filters. It's a little bit of a pain to clean, but a little bleach solution and voila, it's clean. For our needs, this has been a much better humidifier and NO LEAKS!!!!

Mine went out in 2 months. Not good quality in the slightest. Replaced it and never looked back. Also a 20 gallon filter on a 25 gallon tank is probably too small if you fill it up all the way. You should always go bigger. But that's off topic. If it came with the setup then use it until it poops out and replace it. If you bought, return it. I can't speak for fluval but I know I hated the aqueon.

have you had better luck with your filter? Just received mine, have hooked it up but can't get suction. Have primed it, filled the tank first, as mentioned in another post. Have not shortened the length of the tubing as yet. Any advice?

I would make sure you have a vent on tank. I noticed on mine with a gravity feed it would drain very slow so I installed a breather. Worked great after that.

make sure the intake is clear. mine gets algae and 'junk' in it and it need cleaning regularly.

You may have to contact Fluval directly for a replacement. I could not get mine to stay attached and my light fell into the water twice. I no longer use it. This was my biggest complaint.
