2 darts or a Hammerhead?

[Salty Dog]

Its always better to have a little more in reserve, just valve it down a bit. Thats how I did mine and its perfect. Dart Gold

what are you trying to do? How do you plan to use 2 darts?
I power my entire system (returns, 'un-closed' loop, skimmer, frag tank, chiller, reactors) with 1 hammerhead gold...very happy with it!

+1
I run mine in a similiar fashion.

As I said, can't tell from pic, but 2" bulkhead requires 3"+ hole
I think two 1 1/2" drains can handle the flow from hammerhead, BUT, if one were to clog...it could be a problem, which is why I'd prefer add'l drains or larger bulkheads. Dart is about 2000gph (I think) so that should be enough flow, in combination with the 4 other PHs.

I aggree they will glog eventually...and sooner than later. You might want to use all three size holes as drains and use a sea swirl/motion return. this at least will give you close to enough. I have 4 2" drains in my tank.

I run two eheims on my 350g. Just in case one craps out I wont come home to a tank full of dead and dying fish. Return pumps can last for years and years but not forever.

+1 like Randy said REDUNDANCY ! I have four 1 1/2" drains, plus two 2" 'emergency' drains on my 450g DT. Basically impossible for the tank to overflow.

i'm pretty much open to suggestions. i could do either as far as the chiller is concerned. I have a ASM G4+ that is powered by a sedra 9000. I beleive it has 2- 2inch drains. i think that shoulb be around 2600-3000 gph. might also want to hook up reactors to the pump also. The stand is pretty much enclosed except for the back.

I only see one larger drain which I'm assuming is what you're referring to as the 2" drain....am i missing something?

Yes...you're missing the pic of the OTHER corner overflow!

Not setting this particular tank up anymore it wouldn't fit in my elevator. But am currently looking for another tank that is 6ft x 30 inches.
