What size Bulkhead for (Acrylic) 1000 GPH?

[DTECH07]

Doing a Bean Animal and i'm not sure if a 3/4 or a 1" should be used. It will be for a 75 gallon Acrylic 1/8" thick?

when in doubt oversize oversize oversize

you better go bigger for 1000gph. I'm running 900gph on 1" and I wish I could have gone larger.

Ok does anyone know GPH according to diameter. It's a Bean Animal so there will be three but two for return and one as emergency.

I an pretty sure the system is set up for 1 1/2'' plumbing, BUT the bulkheads are 1''. Handles up to 1500 gph.

Thanks Peppie I'm going to go with 1 1/2"- 2" BH, I figured since I'll be able to dial back the flow then larger (ensuring the acrylic integrity isn't compromised) is better.

IMO 1 1/2'' will provide much more flow than you will want to run thur your sump.

I'm going to stick with my original plan and do 1" I will have the ability to dial it back on both the Return and overflow side. Thanks again Peppie.

IMO a 1 inch bulkhead will safely take 600-800 gph, now is your 1000gph before head pressure ,the head may take it to 700-800 gph.

Sorry for delayed response Red C, I found on RC a calculator that helped me with not only the GPH but also the Head pressure. Thanks
