treesprite November 15, 2019 Share November 15, 2019 (edited) The siphon-break hole in my Sea Swirl output is too high, so a stream of water is kind of spurting out above the surface of the water, causing spray and bubbles, and making the only water noise I can hear (because of better overflow setup - I'm so happy!). It wasn't too high in use in the 50g, because that tank had the water level scarily close to the top of the rim. I didn't want the water that high in this tank for which I had the option of putting my overflow lower, so my water level is just above the bottom of the trim so I can't see it, but there is an inch of room so water isn't going to go on the floor if a snail sits over a single gap between 2 overflow teeth. So, what do I do about it? I have enough space in the sump to take up what looks like would be about 5g of back-siphon water should I decide to block that little hole. There isn't really anywhere else to drill a hole lower, since that would just be where the water comes out. I don't feel like putting a longer fitting on the SS just to be able to drill a little back siphon hole a quarter of an inch lower.

tom39 November 15, 2019 Share November 15, 2019 How far under the surface of the water is the hole? Without seeing the issue, a guess at a solution would be to place a small hood over the spout that would diffuse the water spout before it made it to the surface. A picture of what you are seeing and what is happening would be helpful. TomSent from my SM-G930V using Tapatalk Link to comment Share on other sites More sharing options...

Origami November 16, 2019 Share November 16, 2019 I used to zip tie a small piece of open cell foam over the hole and it silenced the stream without blocking the siphon break. Link to comment Share on other sites More sharing options...

Great idea, I'll give it a try. Edited November 16, 2019 by treesprite Link to comment Share on other sites More sharing options...
