Had a terrible temperature spike to 30 32 , lost many sof corals and mushrooms and rics sadly...
Sustrate also didn't look as good as before.
I removed all of the rocks and substrate , just abit left now .
Got a chiller and reset all the rocks , didn't have my full flow in until a few days ago. But my corals aren't really recovering... Rocks all look dusty and lil furry. Looking kak basically.
What's the story now?
A few weeks . . . As the durbs heat came in
Zaxx with temps going that high for that long many things will have battled and or died. It will take a while for a tank to come back from such an episode and things most likely will be out of ballance for a while. The corals that have survived will recover, but they will need good water quality for a length of time, as will the rest of the tank. Thats the bad news
the good news is there is lots you can do to help the tank recover propperly
I see you say you have a chiller and I am taking the assumption that its installed now and that the temp on the tank is down around the 25 mark?
Is you tank up to full internal flow now, all circulation pumps working? Do you have them on a controller with good random flow?
I would dose with a bacterial sollution (my personal preverance would be 'stability' but you can get a number of different barnds to use) Dose as per instructions on the bottle and give the bacterial population (which is the backbone of your biological filtration in a tank and would have been hammered by those temps) a chance to recover. You def want to dose bacteria (for a number of reasons) but not the least of which is that there is a good chance of cyano bacteria establishing and outcompeting you other bacterial strains which you def do not want. cyano isnt a huge monster to deal with if it does set in, but its a very good chance that it will come in this case, so does with bacteria now.
Water changes are critical now. a good routine of 20% per week (if you can depending on tank size and vollume????) will realy help. But before you do a water change take one of the power heads and 'blow' it over the rocks, deep in the reef and all over the place except the sand which you dont want to stir up in the process. You will get lots of that 'furry stuff' as yopu call it into the water collumn and when you take the old water out you will get lots of it out at the same time.
But for the rest, just keep the tank parameters (especially temp and SG) within good levels and constant and the tank will bounce back over the next few months
