is their a standard when selecting Dia. for plumbing

as the title suggests.
is their a standard when selecting Dia. for plumbing is my ? as im looking to purchase the fittings for my 110gl.
it will be predominantly sps corals. (lots of flow needed)

 

Depends on the bulkheads used and if its a reef ready then you have to use as a rule the 1" drains and 3/4 supplies from sump..I run 1" on this 180 on a 2" bull headed tee to the sump 40Ft away I ran a 1" back from pump then I split it to 3/4 feeds . If you drill the tank then you can use any size you want to But 1" and 3/4 will do fine ..

Now if you go to an internal circulation then you want volume and the pump would dictate that pipe sizing . Like my pump is 2" in and out so its fed with 2 1.1/4 lines to a 2" tee to the pump inlet and then as many bulkheads needed 4 6 8 to flow circulation water internally .

So we would need to know what plumbing you are dealing with and then pump sizes and flow rates you are trying too achieve

 

waste: there is no standard, heres a site for a generalized flow rate based off of pipe size

GPM/GPH Flow based on PVC Pipe Size, ie, How much water can flow through Sch 40 Pvc Pipe Size 1/2" 3/4" 1" 1.5" 2" 2.5" 3" 4" 6"

 

Ahh OK I was thinking about a recurculating the water internaly with one pump and renning all of my other gear(skimmer,phos reactor/sump equip)with another oh this is also going to be a 3sided deal with acess from top bottom and one small side same as Otty but smaller lol.

 

still cant remember the name for a 3sided veiw tank damn lol.

 

you could run one of the closed loops on the chiller, two pumps for the system ( incase one stops running ), another for the skimmer,phos,Ca going back to the sump, drain could handle the refuge.

but the drains would have to be larger than the intake to handle the extra flow.
