ASM G2 not working properly

[cprowler]

I have a G2 and have the same issues that you and Tony have. I have been doing the cleaning that Tony mentioned just not as often. I have considered doing the reserc and/or the gate modifications but am most interested in the mesh that Tony mentioned.

I didn't know if I just wasn't feeding enough (every 2 or 3 days ) or what.

Tony - Are you going to post your mods in a thread?

[Delphinus]

Yeah, will do. I'm just waiting for the airflow meter to arrive in the mail so I can do some "before" and "after" measurements to be sure that I've made an actual difference.

FWIW, my G3 has the recirc mod and the gate valve mod.

Once my G2 hits max capic. after 3 or 4 days , that seems to be it. I am starting to wonder if it has to do with the "crud" that builds up at the top of the riser tube. Once it gets too "brown" and thick around the top that seems to be it, the skimmer stops producing. Its like that crud prevents anything from going over the top into the collection cup.
Does this sound familiar Tony and cprowler?
H.

I get the band of crud around the top as well, seems to have no effect, though when I empty the cup, I usually wash off.

Hmm, interesting. I'll have to watch for that effect. It could be happening for me. But it's hard to say. Usually the skimmer works better after I've emptied and cleaned the cup, which could be explained by the crud preventing the foam from spilling over, but then I usually give the venturi a quick clean as well at the same time so it's hard to say, maybe the better initial performance is because of that instead.

Interestingly this last week I've gotten a half cup full of skimmate. It hasn't performed so well in months. Maybe it's heard me talking about the mods I'm going to make on it and it's trying to shape up

Honestly I do find that the venturi is very sensitive. Just a quick poke through with a nail is all I do at cleaning time, takes basically 10 seconds and it ensures there is no blockage starting. Give that a try maybe?

The venturi.... is that part where you hook the air tubing?
I think I will start threatening mine with some mods as well.

Yep .. that's the part. I slip the tubing off, take a nail and push it into the hole, wiggle it back and forth a few times and replace the tube. It's a bit of a pain because it's really tight in my sump but it seems to be worth the effort.
