I'm curious what problems you have seen with them? I currently run an ASM G4X with mods but have also run an ASM G3 and a regular G4. My only complaint would be with the G4 being underpowered by the Sedra 5000 and being too stupid to figure out how to use the gate valve with the G4X mods (I do run it recirculating though). Other than that plug and play and work very well.
I just have never seen anyone relate any problems with them on the boards that I frequent.

What sort of problems have you seen with ASMs?

I do not have an ASM, however from my research it appears these are decent pieces of equipment. Specifically what issues have arisen with these and what is the source of information on the issue?

Most that i have heard is a lot of excess leaking around certain mods that people have gotten, leaking around the neck. There was excess noise caused from the skimmer, there was also a problem with bubbles and even consistantly overflowing the collection cup (no, it wasn't a new skimmer).

There have also been qute a few problems that i have read about when it came to cleaning the skimmer, that when they restarted the skimmer that it was like the first time they fired it up brand new. I dunno, it just seems like a few too many problems.

Are you sure you are not thinking of the coralife super skimmer? All those problems look like the ones I have seen posted all over for that skimmer and not the ASM.

very possitive. I mean, given the THOUSANDS of skimmers that they make, i am sure that they are just a few of the anomolies that may occur.

For those that do have these skimmers, do you notice that there may be some extra crud leaking back into the sump and cause some problems that way or is it so minimal that it can be negated if it got back into your tank?

My only complaints are a slight leak on one of the seals, and they shorted me on the riser tube foam. I only got a 3" piece of foam. Since the foam didn't reach all the way up the riser tube, when the water flowing out of the riser tube was disturbed at the top it would turn into a water fountain, hit the shoulder of the skimmer and deflect out of the sump. I ended up with 10 Gallons of water on the floor of my basement once. This could have been fixed by a) securing the small foam to the top of the riser tube with a tie strap, b) buying a longer piece of foam, or c) adding a gate valve. I went with c) because i end up with one less thing to clean. I even think that I have gotten better production since I added the gate valve, I think because you can fine tune the level perfectly.

As for cleaning the skimmer, I have never had it overflow after cleaning, in fact, it starts skimming right after cleaning, and I never have to adjust the level.

And I am not exaclty sure what crud could leak back into the tank?

I think it might be safe to state that a G5 on a 50 Gallon tank is over skimming! Either that or overcompensating.... :lol:

hmm... so your saying you don't want to see the new skimmer I am putting on the 94gal:mrgreen:

I don't think you can over skim either. You can go over kill - guilty - but not over skim. If you have a skimmer that is capable of keeping up with your system and put a bigger - over kill - skimmer on it a bigger skimmer is just going to get the job done a lot faster. There is only so much to skim. That being said the bigger skimmer will also get things done quickly if you happen to over feed - increase your bioload - or have a problem like something dieing in your tank.
Personally I like the insurance.
