TF - I agree with Doug, I tried this method myself once when i started w/ my first marine aquarium. I didn't have a test kit to see how much benefit it may have had, but I can guarantee you one thing: it makes one helluva mess with all the salt spray you're going to get. there are a few options though. 1. just point the powerhead(s) so they disrupt the surface of the water significantly. 2. (better idea in my opinion) Get a decent skimmer. for one thing, this will remove alot of (I guess not all, but hey, what more can you ask for? hehe) the nasty stuff, plus it'll give you all the O2 in your water that you'll need. HTH,
