MCU research, the company that brings you the lighthouse controller that we first spied at Macna in Atlanta is bringing new add on’s to the table. Up first is the “screamer” it does what you think, it will sense water leaks underneath your aquarium. Besides that though it can be configured as an audible alarm due to excessive tank temperatures or out-of-bounds PH/ORP readings. It is wall mountable and produces a 103db alarm, ow that’s loud! Retail for this unit is $39.99.
