After reading the thread no one here mentioned a auto shutoff. This is also very important if your going to leave your system on and let a float switch turn it off. You can put hundreds of gallons down the drain without it. It a must buy with a float switch
The question would be are the bubbles being produced of the same amount and the same size as before. If there larger or the surface tension is always being disturbed then check your pump and the air intake for clogs

In my exp it does not work. The better skimmer will continue to skim while the other will just do almost nothing except maybe become a real large air stone. If you just have extra ones doin nothin go for it but its a real waste if your going to spend money on two good skimmers

Testing on a regular bases is not always about what I read here and now its about seeing trends. Like going to see the doctor only when you get sick. then when you go you find you have cancer and it could have been prevented if you would have been tested regularly. It like o well sorry dude if...
Just make sure you keep you O2 levels very high or all the bacteria using it will lower your levels and possible kill fish or cause ich in the tank from stress.
