How can I quiet this thing down. It’s a 240 gallon tank with a Trigger Saphire 44 sump. Return pump is a Vectra L2 set at 40ish percent. Drains and returns are all 1.5”. Two issues I’m having is the splashing in the sump. Like the sump drains are overwhelmed. I also have a lot of noise coming from the open drain. There seems to be a lot of water going down the open line. I do have a hole drilled in the top of the open drain and it is out of the water. No matter how a tweek the full syphon gate valve and return pump I can’t quiet it down. Sump noise.
