Loud overflow drain HELP

[Twistedreefer]

I have a marine depot 300 single overflow box I installed a stockman standpipe but it still has a waterfall noise that comes from the plumbing. I also get a ton of micro bubbles in the sump that make noise and is starting to get salt everywhere. Any suggestions on how to stop the noise and the bubbles?

My plumbing is one inch and goes straight down to a 90 to another 90 down into the sump

My only thought is.. the back sides of the u tube fully submerged?

Not good with overflow so only a guess

Inside the sump

Oh no, and if I didn’t say it already welcome

Is the drain tube below they sumps water line?

can we get a level shot on that if possible?

Can you put a sock on the sump input? That will help with bubbles.

If the overflow noise is water splashing in the back box, you could experiment with a longer standpipe. You would need a longer (taller) piece of PVC pipe so the water level in the back box is higher and that might reduce waterfall noise. If the noise is from the front box, then raising that box may also help, but any of these changes could cause overflow flooding risks that you need to be mindful of as you change things around.
HTH.

On what?

Does waterfall sound like it is coming from the skimmer box wet side?

 

[Mastiffsrule]

I can’t tell but it looks like you have air in your u tube?

No I built the standpipe tall enough to keep the water higher in the wet side of the overflow to prevent that noise

No must be a reflection or something

Sorry I was not more helpful.
hopefully someone will come along with more experience on this.

Just wondering about that electrical box mounted behind the tank, that would make me nervous. One accidental splash and yikes

I'm thinking maybe it's the 90 elbows but idk never had this problem
