Backup bulkhead?

[HoudiniR]

Hi all,

I have a 16 gal nano with a 15 gal sump that I am currently in the process of setting up. I am only running approx. 130gph throught the sump so I will be using a 3/4" bulkhead.

Should I drill two (i.e. having one as a backup)?

Thanks for the advice.

Any comments?

Thanks!

i am no pro, but i think you will be fine with one hole

I have a 46 gal. tank and I drilled two 1" bulkheads. From everything that I've read most folks feel that overflows will fail. If you have two, versus only one, the probability of disaster is lessened.

Every drain in my system has a backup. My display tank, my skimmer tank, my fuge, my lagoon. even my frag tank has a back up drain.

I am running into the same question. I have two 1" drilled bulkheads in my 37g. I was going to use one as an overflow and the other as the return. I just dont know what to put over the return bulkhead to keep fish from swimming upstream into it.

Uhhh, I have never had problems with fish swimming upstream into a return. IMO that is not an issue.

I know a guy who has a 71 bow and he only has one 1" bulk head and it works fine for him and his fowlr tank

little scenario: Fish dies clogs bulkhead. Pump throws everything in sump into tank. No water in sump, heater cracks, Controller senses pH levels low it dumps contents of Kalkwasser into sump, Pump continues pumping contents of sump into tank, pump is history tank back siphons through pump back into sump.

Little scenario II : Your kid drops her "Nemo" stuffed animal in your tank. "nemo" clogs bulkhead; refer to scenario number one.

Litte Scenario III : Your prized pumping xenia cancels Christmas. Gently floats to the one bulkhead in tank. Refer to scenario numer I.

With the bulkheads being about 2 inches below the water level I just figured I needed to get something onto the return bulkhead to at least create a way to keep it from backsiphoning in case of electrical outage. I am unsure as to what I can fit into a 1" bulkhead.
