Some skimmers do work better than others. This is a correct statement, I personally like ASM skimmers. Each tank needs to be skimmed a lil differently...some believe one can never over skim, while others believe you can. So it depends on the tank. Myself I believe someone can over skim a tank, process's have shown that skimming does indeed pull out many MANY waste products in a tank, which is great for the tank, but at the same time it is pulling out good bacteria as well. Myself I " under " skim my tank...on my 150 gallon tank, I have a skimmer designed for a 55 or 75 gallon tank,...I forget right off hand, But in my refigum I run macro algae ...to take care of the excessive nutrients. Remember a sand bed set up correctly with live rock is your best friend, but seriously PLEASE remember that rock can be a nightmare for water flow, so you need to plan that out correctly as that is were a TON of waste will build up...causing a tank to crash. In a month I will be moving, and hence taking down my tank...when I re-set it up im going to take pictures on how to set up egg create correctly so you can have good water flow, and at the same time not see it.
Hopefully that will help alot of people in here with there aqua-scaping.
Also a common problem with alot of tanks is people will lay sand down first, and then place rocks on it. this will allow bacteria to build up at those points, best way is to set the rock in first and then build the sand around it. Also make sure your cleaning your sand on a regular basis...as deep sand beds are toxic dumps.
If you follow the general concept I have laid out you wont need a " MASSIVE " skimmer, nor will you have to " over skim " your tank for it to be healthy.
sorry for ragging on.
