I am setting up a new reef ready tank and cannot for the life of me quiet the noise of water entering into my sump. This tank employs the typical 1 inch drain with the 1 1/4" stand pipe. My return pump is a mag 5 and the return line has two 90 degree angles in it.
I have read countless threads about how to make a durso quiet and I have had no success with this at all. I upped my 1 inch drain line to 1 1/4" piping for a reverse durso and it was still unbearably loud. I dont feel like I'm trying to pump a lot of flow through my overflow. I used the calculator on the front page and it estimated about 300 gph after loses. Even when I throttle back the return pump with a valve it is still very very loud.
I have been thinking about switching to a "modified" herbie but see that many people think its dangerous since your emergency drain is wet. I have also read without having your emergency drain wet herbies can be difficult to properly adjust and since I only have two holes I wouldn't be able to have both.
I guess I will just number my questions to make it easier.
1) When I insert a piece of air line tubing into the hole I made in the cap on my drain it immediately starts flushing repeatedly until I remove it. What is the cause of this ? Do I need a bigger tubing?
2) Do modified herbies need alot of adjustment to keep the balance between the return and the drain? The thing I really like about the durso is more stable but I can't live with this crazy noise!
I have been tinkering with different drain configurations for about a week now and want to get my set up started but can't do it until this noise business is settled. There are so many people who use durso overflows I know there is a solution I'll just be damned if I can figure it out. :headwally:
Any advice would be greatly appreciated.
