It can be ran externally and imo work as well as internally if done right.
It can handle a 150 but is close to its limits there and if you plan a mostly sps tank i would try to go with one of the pro models.

Just got my Reef devil 750 in I was thing about connecting the down draft tubs like this not sure if it will be beneficial for the skimmer or should I leave it AE tech way 1st set of pic's is the new way of setting it up the 2nd is the way the skimmer came. Open for any advice on what I should do.

the way you intend on doing it will probably limit the flow and pressure more then the original way.i would leave it original.
if its not broke dont fix it, i always say

i was thing about just adding a Y fitting off the pump to eather side of the tubs

IMO, I don't think you will see much difference either way because you will end up adjusting the output flow with the ball valve anyway...
If it were me I'd put a union on the single input picture. You want to be able to disconnect it easy to clean it, or adjust the bio-balls. That was the hardest part for me getting the bio-balls to stay. See the thread above.

I've had a reef devil since around 2000. Works great. It is sensitive to oils from your hand and I suppose when you feed the tank as this causes the foam to collapse, but it only collapses for a short period. If the exit spout is submerge in the sump the water level in the sump will effect the wet/dryness of the skimmate, I solved this problem by adding pvc so that the spout is not effected by any fluctuations in the sump. I do not see the reason to change this skimmer, it uses a pump rated at 700 gallons an hour so the electricity has never really been an issue. I've also read on other post of people complaining that their skimmers have died and they are replacing them, do not know exactly what would cause a skimmer to lose it's ability to skim, I believe their issue is probably due to their pumps, perhaps all the air that goes into the needle wheel of non-downdrafts skimmers causes the pumps to fail prematurely, but there is no problem their for ETSS users. I've had the same pump that came with the skimmer 9 years ago and it all runs great.

danjo, can you describe your experience with the wet and dry skimmate when the spout is submerged. Does submerged mean dryer skimmate?

It depends on what your trying to keep and what your bio load will be.
The 600 XR with an Iwaki 55 RLT-Max would be real nice on your tank. Although the 800 would be even better (2 downdraft tubes). Look on RC selling forums you can get a good deal on a used one when they show up.
I would buy one that is rated more than what your tank is. I have an ETSS 1500 on a very heavily stocked 400 gallon system and it pulls out a lot of dark stuff but I want to upgrade because I'm keeping SPS.
The ETSS says tank capacity of 500 gallons but with heavy bio load I'm guessing 300. I'm also using an Iwaki 100 wich is the smallest pump they recommend.
Don't be afraid to add a bigger pump because it will really improve the performance.

Here is a used one for sale or search the for sale forum for ETSS:

I would go with the 600 pro driven by a blue line HD40 or an iwalki 40
More then enough to overskim your tank

I have a evo 750 on a md55 pump that is giving me a bit of trouble. It is plumbed external to the sump on a raised platform that drains down to the sump itself using 45 degree elbows and a tee for air removal so it is quieter entering the sump chamber. outflow is not submerged or blocked.
It came originally with a set of 1/2 inch barb to 1/2 inch mip threaded air intake and collector connections, but also there was a set of 3/4 inch barb to 1/2 inch mip connectors in the box(much smoother flow with no restriction in the elbows). I am running into the issue that I do not know which barbs to use.
on the 1/2 inch set i get a weaker foam head that ends up about at the rim of the cup, but rarely goes over, and its pushed up by very large bubbles (can see though the middle of the skimmer) if i leave this for several days i get quite a bit o collected gunk in the neck at times, but the overall foam head dies down and i have to take the skimmer apart and clean it so it wont keep backing the foam head down.
the 3/4 inch set work to create much smaller bubbles in the skimmer overall, but after about 20 minutes to an hour start overflowing the cup until the external cut off fills and kicks on.
the skimmate is light tea but does stink so it is working. just not very reliably.
I believe the pump is too powerful and needs a ball valve to lessen the turbulence inside, but I have also read here that i should limit the air out of the waste collector, (which the 1/2 inch barbs are doing possibly too much?)
I am using 13 bio balls (manual says somewhere between 12 and 15) and the gatevalve for the water is almost open (about 3 full turns til its stuck open) that means the water level is barely an inch above turn off levels and i am getting the entire rest of the skimmer full of bubbles. which according to the manual is very very low. i need to be about 4-6 inches higher they say. (again what is leading me to think the pump is too powerful)
Any suggestions or which way to go would be much appreciated.
Ive email etss several times but have not received a reply.

It could be the pump is to powerful, try a ball valve to reduce flow then go from there. They recommend the iwaki 40 for that skimmer.

I wish I would have seen this thread earlier. I just bought a new Etss SB40 from aquacave on thursday. It shipped today form AE tech.
Got me a used Evolution 750 today for $50! 
and I already have it up and running with a mag18 in sump with the water level in a stable chamber and gate valve knob about 1" above the waterline.
I think it's heads and tails better than any skimmer I have used before already (and it isn't even set right yet) but I was wondering after reading all these posts.
Any idea how many bioballs I should be useing with a mag18?
I still have alot of adjusting to do but after 11 hours it's already skimming all be it a bit wet. (still wirking with the gate valve every hour or so)
and my other questions is that the collection cup that I can get for this has the auto shutoff ball thing in it but how does that stop the exhaust when the inlet for air and water just sits in the top of the skimmer?
I plugged the drainline and altho the bubble colem did collaps a bit. it didn't stop forming like others I have seen.
If I hook this thing up external laiter is there any chance of an overflow due to this?
I'm running it on a 110g flatback RR hex tank with a 40g sump.
medium bioload ATM but will increase.
Any help would be appreciated.
Thanx

when the ping pong ball rises in teh chamber it will cut off so much air that the foam head itself collapses in the skimmer. it is safe to be outside the sump (i have mine installed that way) just keep an eye on when the container fills and cut the skimmer off when you empty the cup or its liable to spray you in the face with the skimmate in the cup when you take the tubing off.
