Sump media help

  • We are currently upgrading MFK. thanks! -neo
One last thing you can drill a siphon break just above the water line on the return in the main tank to stop back flow when the system is turned off or you lose power. Also can add a check valve near the pump side of the plumbing

I would also suggest that you put your media in lingerie bags or some such for easier maintenance

I was planning on putting in a one way valve in the return pipe, but what you suggested might be easier.

I did think of that one, I had to improv.

I'm not sure I understand your question.

The second one is purely a back up overflow in case something goes very badly and the first overflow becomes blocked.

The picture helped. So the overflow drain set-up looks to be a "Herbie"? You have a full siphon and a second emergency drain. I have a similar set-up but I typically have a trickle in the second drain and completely dry third drain.

Anyway, what I suggested was to have the edrain go to a sock rather than directly to your biological section. But I see how you may want that to raise attention if your e-drain is taking in flow?

I've managed to get it running silently without the trickle in the edrain. I'll see if that holds, if not I'll put a sock on the edrain. I do want it to get my attention if it is running like that though.
