ASM mods

[Burgman]

Hi,

I am seriously thinking of buying a ASM G3 skimmer and noticed the two modifications that are available. Are the mods really needed to make the skimmer work properly or are they just nice enhancements?

They are nice enhancements.

The gate valve mod does not make the skimmer work better. It just makes the skimmer easier to fine tune.

The re-circ mod did seem to make my skimmer work a little better but it not enough to say that it is a must do mod.

I totally agree with DocG. I got the gate valve mod, and it makes things a little easier. I do not have the recirc mod as I do not want another pump for input, and am not smart enough to connect it to my overflow pipes. The G3 is an awesome skimmer for the money. Good Choice.

No recirc mod, but the gate valve mod is great for fine tuning.

Anemonebuff, how is your gate valve set up? It looks different than the ones I've seen.

You can actually make the mod just about anyway you want. I have it so it is easier to adjust. And fit in the sump better. I'll get a better picture for you.

That's 48 hours of skimmate.

on my 90 I now have my g3 fed directly from the overflow and when i did that my skimming efficiency shot up and skimmate production more than doubled. Now i have to empty the cup it out once a week because it is full and about to overflow, and the skimmate is darker than ever. I suggest anyone using a skimmer capable of rec. and direct overflow feed try it out. I have my return pump, (500gph) also feeding my refugium and a phosban reactor running carbon, so i figure i am getting maybe 250 into the skimmer, which is more than enough based upon results. My water is crystal clear.

I've thought about adding a 90 degree elbow to the inside of the skimmer , connected to the pumps inside flow of water. This way the flow would be pointed right to the bottom, creating more bubbles, and more surface time for contact.

Whatta ya think ???

 

[Anemonebuff]

I have thought of the same thing, except that I would have it go into a cup or cylinder so microbubbles do not escape the skimmer body.

i have heard of using a 45degree elbow for this, and i may try it, but i first have to get at the inside of my skimmer, which will be some time. I agree that it would lead to more dwell time for the bubbles, but it will also add head pressure to the pump, perhaps cancelling any gains made. certainly worth a try though my skimmer is working so well now that i don't think i need it to do anymore.

Hi All,

Thanks for the input, looks like the gate vave mod will help.

BTW, the way Anemonebuff did his setup, is a far better way than I did mine...

When doing this, place the valve so the handle is facing up. I think it's much easier to control that way.

 

[Anemonebuff]

I wasn't sure my way was going to work when I did it. I figured that the gate valve had to be before the vent tube, so I set it up that way first, and it was a real PITA to adjust. I do have the vent tube a little high just to be safe. I tried it my way and I guess as long as there is enough restriction on the outflow it doesn't matter. I am in no way any plumbing mastermind, just a victim of accidental success.
