Hidden Closed Loop Intake

[banditpowdercoat]

Mark, is that overflow noisy? Another reason fro me to have my standpipes high is to mimize the water fall noise from the overflow. Acctually, it works. Because last week, the air inlet to to durso got a little plugged with salt creep. So, the drain was siphoning, and the resultant noise from the larger overflow drop alerted me to something not right with the tank.
