Aquaclear HOB ?'s (loud, etc.)

[gemini69]

I have a 30g tank that's been up and running (no fish yet) for about 2 weeks. This is my first tank and my husband's already complaining about how loud it is with an AC70 HOB filter. We keep it in the same room as our TV and the "waterfall" effect is rather loud (although I find it a pleasant sound). How close to the top of the tank can I raise the water level? I have it about an inch or maybe a little more from the top of the tank. Also, don't I need the "waterfall" effect or movement on top of the water to help with oxygenation? I'm afraid if I raise the water level too much that it won't create enough disturbance to help with oxygen, although I'm guessing it would be quieter.

I understand some of the canister filters are much quieter, is that correct? If so, do they still create enough movement for oxygen to get in the water or do you need an air stone or something with a canister filter?

I might be totally misunderstanding how oxygen gets in the water so feel free to correct me. Thanks.

yes you can raise the water surface so that it has no waterfall effect at all.It is true that more oxygen will infuse with a waterfall however more then enough oxygen will incorporate into the water column just by the action of the current it will create.I have a hob on my 29gal which I have running with no waterfall effect at all,oxygen has never been an issue.Canisters are not always quieter but in general they are.If the hob is filtering your water well then I wouldnt change it for a canister.

Thanks folks. I"ll raise the water level and see if that doesn't bring the noise down to a more acceptable level. :-)

One thing I've noticed with the my AC filters is the cleaner they are the faster that water comes out of there. I just recently broke down my AC 50 and totally cleaned it and I guess the water is just rushing through there now because I really notice the water fall sound now.
