Just wanted to say thanks to all who have helped me and others on this forum. I started this project (hobby) in Jan 2014 and have to this point in time have succeeded beyond my expectations with the set up of my 90 gal. fish tank only and QT . Have not lost any fish and the eight chromis's in my QT are all most ready to come home to my DP tank. Boy are they going to be happy fishes .Lots more room LOL. I cannot image the trails and failures of the folks who do not have this info resource from this forum and the expertise that comes from the generosity of it's contributors. Thank you all.
