why express lies
Yeah... I'm sure the carbon filters with all that surface area are designed to USE that area to absorb odors. If you build a box around the filter, your making the fan work harder than it has to and you're defeating the purpose of the carbon filter as the CFM will be drastically limited.Building a box around your fan is a great idea. Another thing, if you have the space is to build an enclosure that your fan and filter can fit into. Line it with "egg crate" foam and remember to leave enough of an opening to allow fresh air in. The foam works well to absorb that sound.
maybe im just stoned but i dont get it... but i have a dual air pump (2 air lines on one pump) and the thing is pretty loud.Ok I just discovered something. A t valve has three connections (not what I discovered). Hook two air pumps together, run the third airline to your water and attach the air stone. Plug in only one pump. Its quiet. At least for me it is. If someone else can replicate this let me know. Note: With two different air pumps in use I didn't notice a difference if one or the other was plugged in.
