I am running the seaclown on my 30gal, it is not way over rated for your 25gal as I fell seaclown overrated there skimmer. You are going to give that skimmer atleast a week or to for it to break in. I would highly suggest taking the air adjuster valve that comes with the skimmer and throw it away, replace it with one that will be more percise to adjust. I used a air adjuster off an old penguin power head I had, the skimmer worked 100% better and I didn't have to fool with it every 10 seconds. I belive you can also go to Lowes/homedepot and find one. Here is how I set the air, 1. completly open air valve till you will notice an air pocket in the U tube that goes over the top of tank. 2. Slowly close air vale till that air pocket gets sucked down the tube and leave it alone. Thats all I do and I am prettty pleased with the results of the seaclown, I get so much dark foam that it will acctually start to rise out the vent hole in the lid of the collection cup. As far as micro bubbles, it will get better over time but I still get them in the tank just not bad enough to bother me. Also if you use anykind of gel like additives such as "stresscoat" it will send the skimmer crazy with bubbles. There are also so many different modifacations you can do to a seaclown but I found just changing that junky air valve it comes with makes a world of difference. If you would like send me a PM and I can email you a pic of the air valve I am useing, I haven't figured out how to post pics on this forum yet
