Ok I recieved my new tank today with the 1100 series pump. I also bought the 2 oversize filters the recommend for it. The tank has a built in mount in the bottom for the pump but in order for the filters to fit I had to rotate the mount to the center of the tank. Now instead of the pump circulating the water around the outside edge of the tank its blowing directly into the wall of the tank. I was reading somewhere that its better for the pump to circulate the tank. Do any of you guys think its gonna make much difference in the life of the bait like this or not? The tank also has a oxygen valve that causes more or less bubbles by turning the small valve on the tank. How should I set this valve for best results? Opening it all the way causes slightly more noise outside the tank than I want to hear but if its better for the bait I wouldnt mind. Also my last question is what kind of rock salt should I buy and where? Is it the same stuff you make home-made ice cream with from the grocery store? I normally get the guy at neds bait shop to give me a handful or 2 when I buy bait down at santee but I would like to have my own. I did buy some Sure Life shad keeper formula but it cost more than I want to spend every time I refill the tank.
