Well I did another water change last night. I went out approximately 14 miles this time. With the help of a good friend from ANCHOR, we brought back about 90 gals. Thanks for the help adnup,I can't wait to go again. Everything is looking great. Very good PE,and the fish are happy. I have to get a better system,for pumping the water from the boat ,to my sump room. I don't think I'm saving money ,with the price of gas,in fact I think it is costing me more. I'll see how it goes.
