Hi Guys I`m new to the site but really need some help, awoke yesterday to find that everything in our tank had died due to a heater breaking and overheating the tank. We lost clean up crew, corals, invertebrates and fish the entire fruits of 3 years TLC, to say we are gutted is an understatement it broke our hearts. Anyway we need to move forward and start again so I have some questions that I`m hoping you will be able to answer.\n \nWe have several Zoas attached to the live rock which are obviously no more will these decay naturally or do we need to get them out ? \n \nWe did have a bubble anemone which I fished out yesterday but I`ve heard they release some nasty stuff when they die which may still be in the water how will I know ?\n \nWill the overheating have killed the live rock ? if so can I get a couple more pieces from the LFS and will this repopulate the old rock ?\n \nI am concerned that as the corals decompose we have no clean up crew to deal with it but I don`t want to put them in if it isn`t safe to do so I am going to check water levels tonight, we did a 20% water change yesterday but do you think it would be better to change 100%.\n \nSorry to ask so many questions but we really need some help we are still trying to come to terms with what has happened, we are definately going to buy a water temperature alarm for the future so as not to encounter the same heartache again !
