Ive read several articles and posts which talk about how important it is to make sure that the tank water is aerated. Normally people use things like airstones, powerheads (to break the water surface), spray bars etc. to do this. Ive also heard that the surface needs to be disturbed to break up any film that may form on the surface that would inhibit air exchange. However, in my newly built drilled 75 gallon tank, I have an internal overflow which continually skims water from the surface, and the standpipe (drain) leads to a Biotower with drip plates in it to allow the water to trickle through a couple layers of mechanical media, and the biomedia. Shouldnt the trickling water provide all of the aeration I need? And shouldnt the internal overflow constantly skimming water from the top keep a film from forming on the water surface?
In otherwords, do I need anything else in this system?
Wouldnt adding an airstone/bubblewand or powerhead to disturb the surface just be a waste of time in my tank?

). I'm glad you went DIY with most of your stuff, BTW. I've read plenty of your posts, and you are getting some great experience in building everything you need. This is also saving you a bundle! Enjoy!
