Ok, I thought i would be able to finally sit down and enjoy my (temporarly) foggy? fish tank. Anyways, that isn't the issue here. My overflow sounds like a toilet. It is very loud. The noise is coming from the overflow box/pipe/tube thing that goes to my bioball box in my sump. I have fooled around with it for the past 2 hours. I have managed to stop the toilet sound, but when i do that not enough water is going into the sump and it makes a gurgleing sound. I have messed with this and i don't think there is anything i can do. If someone could give me tips that would be great. This needs to be solved ASAP. I have read about this Durso Standpipes Portal > Home but i don't know what to get/and how to use it/set it up/or if i CAN even use it. Please help! Here are pictures of my setup.
