Re: Fry Flo-Thru Rack

[Duane Wake <dwake at iopener_net>]

Hi,

With a flo-thru system using shoe boxes I like to have a small stream of water going into the boxes, that will give you good movement of water and do wonders for your fish. I can size up young fry in half the time it takes to do that in a tank. Will you spread disease to the other boxes? yes but that was the question that held me back from building my setup about 10 yrs. ago and I have yet to have any disease in those 10 yrs. You can run your water thru a U/VSterilizer if it`s a problem for you but I don`t think that is necessary, I never did. Another plus for the flow-thru is that you can do a complete water change for all the boxes by changing the water in the sump and not have to worry about shocking the fish. Just take good care of the water in the sump and you will have it made. Good Luck.        Duane
