Cold weather

[Viet-Tin]

Well i caught this weird 24 hour flu or some sorta sickness and while I was out I forgot to plug in my heaters well this morning my tank temp was below 65...I rushed and plug my heaters in and turned them on to 80 and my temp is slowly raising up. My brain coral, bta and some of my sps frags arent looking so well and some are starting to melt away...is there anything I can do to help the survivng critters?

They can look shocky but still recover. Don't over react first of all. Fixes are sometimes better made after taking time to think it all through.
Make sure your skimmer is running hard to put oxygen into the water as the temp increases. If you have an extra one, start it up too. Increase the laminar flow in the tank if its not already ripping the surface, add a couple power heads aimed at the surface or increase the Streams to move water but not provide a blast at or too close to any one coral. Keep hard flow away from the corals, just move the surface a lot and let the water move the water to circulate around the corals without putting debri into the water. Your tank is probably already like this, that would be good. If RTN sets in on an edge anywhere and its not enough to siphon out, use the very gentle pumping/blow from a turkey baster to remove the bad tissue. Keep after it. If it continues, you may be forced to frag sps. They will grow back if you get it soon enough. Turn the heater back a little. By now it should be warm enough. Definitely don't want to over shoot the temperature. You can raise it back to the normal 78 or whatever you keep it at over the next couple days. If you have tangs, don't panic when they get ick and don't try to fix it with some potion. Just have faith that they will make it as things improve. If the corals bleach, be very careful about changing bulbs. They will have to be acclimated carefully and will color back to something over months. Feed the fish smaller amounts but more often, as much as they are interested in. Be sure to check the tank as soon as the lights come on in the morning to clean up any really stressed corals, if any. If you work, can you take off for lunch? If RTN sets up, it can really mess up other corals nearby if not cleaned up on the one it happens to. Make sure your refugium light is working. If its reverse cycle, extend the time a little. Don't drip quite as much kalk tonight. Cooler water, more dissolved O2, pH will be higher at night than normal so you don't want to overdose with kalk tonight. If the corals are really stressed, add a carbon canister filter. It would be a good idea to do that anyway. If your water quality is high already, that won't increase clarity much but will help remove toxins resulting from this. If you use ozone, cut it back or don't use it right now.

Good luck, I hope it goes better than it seems. Make sure to install 2 good quality heaters with thermostats as safety devices to prevent this from happening again, then house temp will not be so much of an issue. Put them in the sump. (The reverse is true in summer time, a good fan and controller in the hood will help on the hotter than normal days.)

My temp has slowly risen up to 75. Some of my smaller frags that I tgried saving from rtn arent looking so well. I think I will take them out if the begin to melt. Almost all my coral are starting to look better as the temp rises. My house is warm but my tank sits in the garage so I cant keep the temp in there constant. I went and wrapped my tank with some insulator hopefully thatll help. All my fish are doing ok I just stopped my kalk drip and unfortunatly Ill be leaving for houston early tomorrow morning so I wont be able to see my tank when lights come on. Thanks for the help hopefully my critters are ok and that this will never happen again.

If its not a 1 day trip, you probably need someone to give your tank some extra TLC right now. The risk is high, even with the extra attention.

Yea im going to be calling like every hour haha. Mt temp is back to normal and looks like my small sps frags have melted away :( but everything else looks fine.
