This is the only other site I know that has some mod info:

Your welcome. I liked the ASM site. I usually save the web pages in MS word format so I can reference later for stuff like that. For some reason I forgot. I have a G3 on a 100gal total system volume so I am going to hold off on the recirc mod until I upgrade to a bigger tank. I have the mesh mod done but not installed. I am just running the gate valve and getting a full cup of dark stuff every 5-7 days with my light bio load. As soon as I get my lazy butt to pull the pump out I will put the mesh mod in.

Hey all,
Wow, there hasn't been a post in this tread for a while, but I thought I'd post an ASM question here instead of starting a new one...
I have been thinking about doing a recirculation mod on my G1X, however, is it really worth it? Will my skimmer perform that much better? I'd like to have my CS50 overflow drain right into my skimmer, like the picture below. But I have one question, would my CS50 be feeding my G1X at an adequate GPH rate?

Or is it just not worth it?
Thanks!

Alan,
Nice looking modes so far.
Thanks for posting it's really hard to find info on modding the G-1x. What size pipe did you slide into the grey exit on skimmer?
On my G-1x I've done the mesh mod and drilled the Venturi feed tube a little bigger also replaced the air hose with a wider inner diameter hose. These made a big difference. Next on my list is either the gate valve or the T with the angle cut pipe you rotate to adjust. I'm also planning on the recirc mod. I'm not sure but would think a direct return feed would cause the water height to flux to much.
Post more pics, have you given it a test with the current mods?

That picture is actually just a picture I found here in the Archives... However, I have mesh modded, bored the venturi, and gate valved modded my G1X. I purchased the Uniseals needed to recirculate mod my skimmer, but I've just been thinking on how to directly feed it... As for pipe size in the exit, I believe it's 1.25" PVC.
I'll post some pics of my setup manana...

Nice too see this thread revived. I just bought the G4x.
Anybody know what the extra 3 tubes of foam in the box are? One seems to be the same size as the pump intake, but the other 2 are smaller. And..No...I'm not talking about the foam discharge tube. These are solid tubes about 6 inches long of the same material as the discharge tube.
Anybody have a mod for a drain? I know it's a simple hole, but where can I find small drain parts.
Thanks.

Great thread, very much appreciated.
Now for some help
I recently acquired a ASM G3, it is stock with a Sedra 5000 pump, it has all pieces, nothing is missing, I have it sitting in my sump in about 10 inches of water - the stand pipe is as low as it can go, but even then it is just ends up filling the collection cup with water, there is nothing I can do to stop it, it just starts shooting water out of the lid although everything is fitted correctly.
I have had a ASM G4+ before and never had any problems... What am I doing wrong, what can I change?
Btw, the skimmer was purchased used from a local reefer.
Thank you in advanced,
-Mike C.

Hi ZURCSREEF,
I would first try lowering the water level in the sump if possible. That should add some back pressure to the pump and lower the GPH. If that doesn't work, it is possible that the stopper in the standpipe is broken or damaged. That would allow the pipe to go all the way down to the bottom blocking the output. To test for this you could try raising the pipe slightly (Like a half inch). If the water slows, you know what the problem is.
Adding the gate valve mod may make the situation worse at this point. Adding the 90 at the top of the standpipe would only add height to the output.

My stand pipe is not all the way down to the stop. I pull mine up so that my output on my gate valve is just below the surface of the water in the sump. How much flow do you have coming out of the stand pipe? Here is a pic of mine. I took the long straight piece of pipe off of the output. There is just the 90 degree elbow after the gate valve. I turned the elbow slightly so it is just below the surface.

Bottom line is your pump is putting water into the skimmer faster than it is forced out by gravity. Lowering the water level around skimmer means more water in the skimmer above water level of the sump so more gravity and more force to push it out.
If you can't lower the it far enough for gravity to push it out fast enough and your output line is totally clean (nothing slowing the output down like the gate valve or gunk) and the output tube is as low as it can be then you only have 3 choices:
1. Put a gate valve bewteen the pump's elbow and skimmer to back pressure the pump so less water goes in.
2. Put a gate value on the intake of the pump to restrict how much water it can pull in...THIS MAY WEAR YOU PUMP DOWN FASTER AND SHORTEN ITS LIFESPAN.
3. Get a weaker pump, but make sure it has a needle valve and the same output setup so you can hook it up. You'd have to research the pumps available since I know the next pump down is the Sedra 3500, but I don't know what the output size it.
Keep in mind you may be reducing the "capacity" of your skimmer with any of these options!
You best bet is to get the water level down and the pipe down. Do you have a picture of your setup?
