Vortech Noise

[Aflac]

My glass is 3/8" thick and I've tried both 1/2 and 3/8 settings on the pump.

The problem I run into is that it'll be quiet right when I adjust it and then it's like it's slipping down the glass or moving slightly that's causing it to vibrate.

I might have to take it apart like you said and check to see if something is wrong.

Just a little frustrated with it all right now.

I'll set it up at night quiet as can be and by the time I wake up it sounds like the tank is going to shake apart.
