It allows me to sleep at night. Unfortunately my setup isn't the quietest system I have ever heard. I still have a little more sound deadening to do but it is much better than it was. This tank is in my dining room so it needs to be pretty quiet. This room is about 20 feet tall so that allows whatever noise there is to be amplified through out my entire house.stingraybob;2991784; said:just out of curiosity, what purpose does the insulation serve?? i know what insulation is for but ive never seen it in a tank stand.....
