I have a 90g fowler with a HOB
The tank is in a classroom and I'd like to install a sump to help quiet the noise and also increase water volume.
The tank has been up about a year now and I have absolutly no idea how to accomplish this. All I know is that the tank is not drilled and I have 18" by 48" of enclosed space beneath the tank.
Are there any "sumps for dummies" links or resources to get started?
