It was a sad sad day this mornin.

So I've been fighting an algea bloom, nothing unusual for a new tank, I bought a yellow tang and thing we're looking up. After about three weeks the tank was getting clear of age then bang and bloom. Yes I was doing 20 gal water changes ever weekend. (45gal tank) so I decided to try a new product that someone had recommended, the rea sea phosphate remover... I must have over dosed and sucked all the oxygen out of the water and killed all my fish, yellow tang two clowns a fire goby, a Dimond goby, and two green chromies. I've learned my lesson and now I've done a 25 gal water change and will not be adding fish for a few weeks...
