you know, I never even checked to see if there was a temperature drop from the top bucket to the bottom. I will use my lazer tomorrow and check that! Its actually amazing to smell how much the air around the bucket gaps stink when the water is running thru. Our well is higher in iron but nothing extreme but the smell deffinatly has a rotten egg smell to it. I thought about the black hose heading to the cage and right now I am going to just run it at night so heat isn't a huge concern right now. The feed line running from the house is 350 feet long but is totally in the shade as its running entirely thru my hard maple bush. The only thing I have yet to do and will be happening this week is I am going to get some 1" ridged foam and cover the top (sides down to the water)and also I am going to put 4x8 sheets on all 3 sides as well as along the dock.I will have blocked the sunlight to aprox 250sq/ft in the cage area and I am thinking I could possibly run even 2-3gpm of water durring the day or the hours of say 11am-4pm while the sun is directly casting light on the pond to just keep the water on the cool side but well oxygenated.
