Questions - Need some input

I see on a lot of photos of tanks a lot of turbulance on the water surface. Should I point one of my pumps up towards the surface? Is it benificial for the o2 exchange???

since starting my 125 gallon reef tank with 25 gallon fuge i have been adding aprox 2.5 gallons of make up water per day. There seems to be high humidity in my house so I bought a dehumidifier. Ironically it pulls about 2 gallons of water per day out of the air in the room. My question is "can I use the condensed water as makeup water? It must be pure water. Thanks Kitch

I seem to be having troubles to post pictures from my computer to Reef Addicts. How do you find the url? I posted some pictures on my profile and now I can't figure out how I did it. Thanks Kitch40

I currently have a 35 gal saltwater and am looking to go to a 125-150 gallon. How long should the tank run before adding corals from the old tank.
