Oh no, my mistake that was my new tank. :P
Hi All,
I need a little help. I am in the process of testing all of the plumbing on my new 65 gallon AGA Mega-Flow tank. I set it up in the garage for a test run tonight. I hooked everything up, filled it with plain water and fired it up. About every 10 seconds there is this loud flushing sound and the water level in the internal overflow drops by several inches follwed by big surge of water and bubbles into the sump. The overflow refills and does it again. Any suggesting on how to stop this?
I used the AGA Mega-Flow plumbing kit as suggested. My return pump is an Ocean Runner 3500.
