newbie piping questions - what size return - what size overflow?

[Milad]

Kien thanks for the info on the herbie. I was looking through your threads on your build all morning, very nice!

Why herbie over beananimal? If im going to drill another hole to handle the second emergency then why dont I just go with the beananimal version. Also is your herbie loud at all?

would you recommend your pump for my setup?

I'm sorry to hear that.. and I'm afraid there are no refunds for your time lost.

I'm afraid I don't have any experience with beananimals so I can't comment on them.

My herbie is silent, as they should be once you dial them in properly. The only noise coming from the system should be the overflow of water into the overflow box. The higher that water has to drop the noisier it will be so if you do go herbie try to keep that to a minimum. Granted even that isn't a huge amount of noise and applies to any overflow system, not just herbies.

I have not had any issues with my mag18. Your tank is virtually the same dimensions as mine, except yours is a little taller so yes, I would highly recommend that pump. It is quiet and so far bullet proof. Prior to that pump I had a QuietOne 6000 which was actually noisier than the mag18. I also had problems with previous pumps where they would not turn back on after a power fail. So far the mag18 has not failed to restart and I cut power to the return pump at least once a week when I do water changes.

Hope that helps!

Until we know exactly what size holes are drilled already it is difficult to determine what is the most effective way to continue, if indeed they are 2" then a Herbie will be fine, it isn't possible to have the secondary drain of 1 1/2 flood with the pump size you are considering I doubt any saltwater pump with a 3/4 outlet could get a 1 1/2 drain to kick into siphon mode..

Having the sump returns at the other end is perfect and should still leave you a little window for the refugium, just make sure the refugium drain is large enough to handle all the flow from the return pump should something happen to the sump returns.

ps the sump returns should have elbows on them to move the surface water down the length of the tank, as long as they are just below the surface siphon breaks are not required..
