OMG this is so frustrating LOL... I cleaned the pump nine ways from Sunday... it looks almost as good as new... connected every thing back up... took off the rise and foam, but the gate valve assembly back on (opened up all the way)... and... OVERFLOW in the cup still :(

Mind you I'm getting a gazillion bubbles in the chamber (as before the cleaning too).

I really do want this gate valve assembly to work... and it did for a while before I did a water change the other day... since that time I can't control the water from over flowing the collection cup.

Talking to a buddy of mine, he suggested that there might be an optimal water level that would make it work. He suggested that the return part of the gate valve assembly should be submerged about one inch under the water line in the sump. If it's submerged too low, or above the water line he says the collection cup will overflow.

Has anyone else had a similar experience and/or can corroborate those findings?
 
or maybe even make sure the outlow is partially exposed to the air so there is NO back pressure - I don't understand the comment about you saying above the water line unless....you mean the water flow is approaching going uphill - as long as the flow is as free as possible is what you are shooting for

, get the sock out of there for a day or so and see....... after a while when everything slimes up microbubbles become a nonissue - many, many experienced reefers run NO mechanical filtration (unless you consider a skimmer mechanical...)

send a pic of your setup which shows water level, outflow, bubble level, etc - lose the sock until you get it tuned correctly

I brought the water level up and I'm going to try it again now. SON OF A GUN!! That did the trick. Apparently there can only be so much that the outflow can be under the water level (and definitely not above the water level).. It's working fine now :) I guess I'll have to closely monitor the water level and top off (I guess my next project will be an auto-top off system.
 
you could always put the skimmer in a container in the sump that will hold a static water level for the skimmer to run in.
 
I would never want to live with a er skimmer that was sitting in water that constantly changed levels - you can not tune it correctly - you gotta fix this

I too, was that excited when the fed-ex man delivered my skimmer. The 2 days before it was delivered I must have looked at that tracking page 10 times an hour...no lie.
 
OK so I am building a new sump for my ES5-2 to live in . I know it should be 6-8 " water hight . Can it be 12" high ? If so will this efect the proformance of the unit ?
Thanks ~
 
it can be higher than that but it will affect performance. if you don't want to affect performance and want to keep a higher water level in your sump, maybe you can make eggcreate or pvc stand for the skimmer to sit on top of.
 
I'll try to give it shot.

Imagine this say you have an air pump. That air pump has a maximum amount of air it can pump. Now say we attach an airline hose to the pump. The moment we do so the amount of air being delivered at the end of airline is reduced compared to the amount of air the pump would produce with out the airline because of the friction between the air and the inside of the airline. The amount that is reduced is a very small fraction though. We all know that as we go deeper into a body of water the pressure increases right. So when we stick the airline into a body of water the amount of air coming out of the airline is reduced. As we bring the end of the airline deeper into the body of water, the amount of air coming out the end of the airline becomes less and less. This happens because the air pump can only produce so much push (pressure) to overcome the pressure present at the end of the airline. Eventually if you go deep enough the air pump will no longer be able to overcome the water pressure and air will stop coming out of the airline altogether.

Now if we replace the air pump which pushes air, with a venturi that sucks in air the same principle is at work. The venturi can only suck in so much air with a certain amount of water flow going through it. As we submerge the venturi deeper into the water it can suck less and less air.

I hope this helped and didn't confuse.
 
I'm putting together a list of equipment for my new tank (62g) and was originally going to go with a ASM skimmer. I've found a new CS5-3 that's within my price range and cheaper than the ASM. The CS5-3 is rated for 90g, so I think I'll be fine with 62g main and 20g sump. If you see a problem with this skimmer on my system please let me know.
 
I have a CS 6-1 with gate mod, extra sedra 3500 (with venturi, needle impellor, etc) that had been in service less than a year that I will see for 70% of what I paid for it - it also has an extra collection cup

I joined the ER club. I purchased a cs8-2. Looks like the newer pump because I dont see sedra on it. Enclosed with the skimmer is a tube of lube. Does this get put around the gasket o ring? I was fitting the collection cup on the base, turned it in place only to find that I was not able to remove it unless I use lots of force. Does the lube make it east to turn? It's real hard to get the collection cup off for cleaning. I am going to install the skimmer this weekend. Any tips would be appreciated. Thanks
 
steve- i have put vasoline around the threads of my union and on the o-ring. this helps it screw and unscrew easier and it seals better on the o-ring.

you sure you didn't overtighten the union too much and that is why it takes too much force to undo it??
