Herbie Drain Loud in Sump

[HLRkpm]

Hey!

This is my first post on this site although I have gained a great amount of insight thanks to you all!

After a long break from reefing, I have recently started a marineland 90 gallon with corner overflow. I have been set up for about a month with the durso set up that came with the tank from a LFS. It was noisy and annoying. While cycling, I figured I would switch to a herbie set up as that seems to be everyones response to fix a noisy durso, as well as relatively simple. I have reviewed many threads and websites on the herbie design and became quite familiar.

All plumbing is 1 inch PVC. I have the emergency drain about 6 inches above main drain. Main drain goes from bulkhead, to union, to gate valve, to union, to sump threaded pipe adapter with final pipe less than an inch below water level. All of this is completely straight to the sump, no 90* fittings, no 45*s, no horizontal sections, just directly to the sump. Water level in over flow is good, just below the emergency drain. I will do my best to attach a photo to this post.

My issue being, when water enters the sump from the main drain, there is a loud splashing and bubbles. I assume this is due to air being trapped below the gate valve, although this assumption could be incorrect.

I am unsure of how to remedy this. Has anyone personally dealt with this issue and found a solid reliable remedy?

Any insight would be greatly appreciated! Thank you!

Extend the drain so that it is well down in the water. Filter socks also help

How would you make the pipe longer if I had filter socks? This may be a dumb question, but how would I remove my filter socks if the pvc is too far down In them?

You lift it off the base and slide it down the pipe until clear of pipe
Do the opposite to change or clean sock

Basically just bring the rim of the sock below the end of the pipe to slide out from underneath the bottom of the pipe. Sump design may hinder your ability to do so.

Yeah, I don’t think I can. The sock is sitting on a holder thing, where the rim of the sock sits on it. The pipe would be going down into the sock, so I don’t know how I would get it off.

I don’t think i can, my sock sits on a base that it smaller than the rim of the sock so it can sit. The pipe would go down into the sock

Mine is the same situation and no issues

If you wanted to extend the pipe, just add a 1” female PVC coupler and press fit a length of 1” pvc pipe that extends deeper down into the sock. To make removing the sock easier, just remove the press fit 1” pvc pipe extension from the coupler by hand when you need to replace socks.

However, if you’re running a Herbie or Beananimal, you really don’t want the full siphon drain outlet to extend more than an inch beneath the water’s surface. The deeper the pipe outlet is, the more back pressure builds, thus the harder it is for all the air to purge from your full siphon line upon startup. So you really don’t need to extend the plumbing outlets more than an inch below the water line.
