We are hoping that someone can help. We have had several tanks in the past. from 29 gal
to 175 gal
. All freash water. Never had a problem with start up or up keep. We recently purchased a 36 gal
bow front. Looks great, have put in the tap water conditioner, checked the ph 7.0 and temp 78 deg. We put in 6 stripped dano's and 6 black skirted to start. after floating them and mixing the water a little at a time. Always used them before. With in hours they were dead. Took a water sample to Petsmart and they tested it and it was good. Gave us new fish and they lasted about 12 hours. We are at wits end. We don't want to torture anymore fish so does anyone have any ideas?????????????
