Can the ASM G3 be used externally?

[9supratt4]

As the Title says. Can the ASM G3 Skimmer with the Sedra 5000 pump be used externally??
If so can I see some pics of the setup??

As long as there is a gate valve mod, I don't see any reason that you couldn't.

Gate valve mod?? Is there somewhere I can find all these mods?? Because I'm looking for the mesh mod too.

Here are a few.......just google the rest

Is it worth the trouble or should I just figure out a different angle for a fuge??
My original idea was to put the skimmer in the sump and use half of the sump as a fuge, but now that I got the skimmer and put it in the sump there is no room for a fuge.

External Skimmers
Pros:
More space in sump or refugium
Usually easier to clean
Easier to adjust
Runs consistently
Cons:
Chance of it leaking
" " causing damage if it overflows for any reason
Takes up more space under stand
I'm sure there are more.......

Great!!!

But wouldn't a fuge in another tank or something under the stand take up room too?? I guess that's not important though......Now I have to figure out how to do that!!!

all the gate valve mod does by itself is make it easier to fine tune water level in the skimmer. The pump still needs to be in water. the only way to run it external is to mod it into a recirc (along with the gate valve and replumbed output) which is about as extensive of modding as you can do.

The stock adjustment tube on a Asm is a slide tube. By changing that to a gate valve you can plumb it back into your filtration. And no, the feed pump can be an external style pump or internal mag drive-type pump. Yes, the gate valve mod makes it alot easier to fine tune. NOT trying to argue, just stating facts on methods I've used before. I no longer run a skimmer externally due to the risk of flooding while I'm not at home.

the output is easy enough to plumb back from being external but the needle wheel pump is designed to be submerged in water. I dont follow the "feed pump". Needle wheel skimmers dont use feed pumps unless the needle wheel pump is recirced. becketts (other venturi nozzle: aquaC spray, bermuda injector ect) and downdrafts and recircs require feed pumps and are all often used externally. perhaps you can show me a photo or diagram so I can visualize what kind of set up you are talking about.

I started a new thread on my refugium setup.....take a look:

I consider the pump that feeds water to the skimmer a "feed pump". I'm not speaking of a recirc skimmer either. There are a few different brands of external needle wheel pumps available with venturi valves built in. I don't have any photos with that on my old system

I used a sequence pump.

oh you mean replace the sedra all together. well yeah you could do that but thats a little more than just a gate valve mod.

 

[coraljunky]

Either way, the skimmer can be external with just a gate valve mod. Yes, the stock needle wheel pump would still be internal. The gate valve will allow you to plumb back into the take as well as maintain water level adjustments.

 

[stanlalee]

eitherway (stock or pump intended to run externally) the farther you move it away from the skimmer the more you reduce its effectiveness. Just the head pressure from the elbow (from pump to skimmer body) on octopus needle wheels were reducing air aspiration by about 20% compared to straight pipes (pumps turned sideways on some newer models). running plumbing from the sump to the skimmer externally will have a simular effect, probably alot more head pressure. its like the seaclone (yeah I know but its the perfect example), works so much better in sump with the removal of the J-tube used for hang on back operation.

 

[coraljunky]

I agree with you. But I was simply answering the question that it is possible.

 

[hurt]

I would never try to plumb an ASM externally, they are notorious for leaking...

 

[9supratt4]

I've decided to leave it in the sump for fear of leakage and also for not wanting to mod it too much. So I'm going to set up a seperate refugium....I just have to figure out how to do that now.

 

[acrylic51]

Nope!!!! They aren't external skimmers, because they will seep, because they aren't actually sealed or welded persay.....the manufacturer advises against running them external, but it could be done if you have a way of dealing or catching anything that might seep.
