Thanks for the info on mag floats - They sound pretty cool - I'll look into them
My tank is glass (manufactured by All-Glass Aquariums) and I thank you for the heads up around the silicone seals. Wouldn't that have been a kick in the head if I cut the seal -- I could see my son looking like the little Dutch boy with his finger in the dike holding back the water.
And one final thing - if all that (for lack of a better word) fuss was about me being humiliated asking newbie questions. Don't sweat it - I am 44 years old - been married and divorced - been rich and I lived on the streets - been a bad alcoholic and now sober - With all I've been through and seen not too much embarrasses me anymore --- YOU ARE ALL THE BEST AND HAVE BEEN VERY KIND TO ME AND MY SON -- FOR THAT I SAY WARMLY - THANK YOU
