I make 2 test on : ER CS250 with gate valve and ER CS-83 without gate valve .
i pull 25LPM with the pump in the CS250 it was to much when the skimmer break in i couldn't reduce the water level (i open the gat valve full) , on the CS8-3 i was able to reduce the water level more .
yes if you will take the gate valve out you will be able to reduce more the water level . if you want you can test it and let the skimmer run after it's work good make a test , reduce the raiser till the end and check where you can low max if you will have enough space then you can mod the other pump to .
if you will be able to run 2 mod pump on this skimmer body then you will see result you never dream on
(you can do it only if you have enough space to reduce the water level )<a href=showthread.php?s=&postid=9055685#post9055685 target=_blank>Originally posted</a> by TekCat
This thread is HUGE!!!!! My eyes hurt
I was wondering, what's the verdict on recirc and meshwheel mod? What I mean, are there the best designs available for both of them? pix, instructions, materials, etc... Is there a "summary"?
wayne reef make the mod recric skimmer (and i suggest to him to mod the 2 pump sedra5000 + sedra9000) the mod work perfect . if you need mesh i can help.

Mavgi: What do you mean by "You can do it only if you have enough space to reduce the water level"? Do you mean reduce the level in the sump? I may try it.
Before removing the gate valve I wonder, the way these come from ER , they extend down into the water level in the sump. Wouldn't it be better to have the output above the water line?

Mavgi, G4X feed is from tank return.. sedra 9000-R/C 
what mesh do your recommend. Can you help 
be glad to reinburse you..

Airline tubing and ozone
Airline tubing and ozone
Does any one know the ID for the airline tubing for G3, I am trying to get the matching tubing that is ozone resistant, since the one sold by online store is bit smaller in diameter which might restrict the air flow into the skimmer and reduce it's performance.
Any recommendation on where I might get the tubing is appreciated also.

Euro-reef sells the same tubing.. Good question.. teKcat
BTW, I have owned a OZ generator for @2 years... found it to be unused/unneeded most of the time.
When you have a "good skimmer" operating properly...
JMHO..

I re-read, mavgi.
The issue is not flexibility in my gate valve. I can turn it either direction multiple turns. Someone just says the gate valve in and of itself reduces the skimmer's efficiency. This is no bozo out there but I don't have permission to say who it is. I am curious as to the responses.
As I said, I'm going to reconfigure, with the valve on teh bottom and have the output above the water line. I think that should help.
And heck, maybe I'll try modding the ohter impeller. BTW I get only 11lpm on my Sedra 9000 with 4 layers of enkamat. I have the Dwyer meter that pulls on the little ball, so I connect the tube at the top and the ball rises, to just above the 10lpm. I was at about 7 with the needlewheel.
Mine is NOT recirc, and the pumps are in the original configuration.

sorry for misunderstand .
first the gate valve don't give option to reduce a lot the water level in the skimmer body !!!
if you take it out and use standart pipe without the gate valve (like the original way) you will be able to reduce more the water level in the skimmer body you want at least 3" down to be safe if you mod the other pump which it will increase more air and water level into the skimmer body .
the water level in the sump important to but i don't know what is in your sump ?

THe mesh i use , if you want send me pm i can supply to you that.
i don't know what type of mesh you use (sorry i couldn't answer to your email , i was in hospital) .
i like to dee the impeller and the setup if you can post some picture it's will be good .
but even if you don't have ricric if you will make it good you will skim better then ever .
TekCat :
i send you PM

enkamat from mfinn ... he had leftover. thanks. modded the second, and it definitely is a better mod (I didn't pull the zip ties so tight this time.) getting around 15lpm on sedra 9000 pump.
the gate valve most certainly affects the water level in the skimmer! turned all the way clockwise, the water level is well above the top of the cup and no skimming. turned all the way counter-clockwise, the water level is below the cone in the main body of the skimmer.
on the g5, which is 36" tall, this represents a difference of a minimum of 15".
with the 2 modded pumps, one pulling about 10 and the ohter pulling about 14, i have the water level set to the middle of the cone (meaning, the point where the bubbles begin to become larger). I'll have to adjust down as over time this point will rise.
in a few days i'll remove the zip ties on teh other and replace more loosely.
thanks.

magvi, I got your PM I am getting some mesh from fellow reefer, he's got some leftovers. I am sure this had been asked and answered bazillion times. I have Sedra 5000 non recirc on ASM G3. Could you repost or point to the meshwheel instructions for this pump please.
Also, if anyone knows does leaving some or all pins on the original impeller makes sense?
