    Hi fellow Reefers

    Can anybody please give me some advice on power cuts?
    1) how long can your tank run without lights, no pumps nothing or how long
    before it gets dangerous for tank inmates?
    2) what is a dangerous temp drop?
    3) what is the best tactic/plan/machine to use during a 12 hour power cut?
    4) is there any recommended supplements to use during power cuts?

    Thanks for the help guys/gals

    If your return pump is not on a back up when the power does come back on your skimmer will overflow into your sump unless it is on a delayed timmer.

    You can use hydrogen peroxide to oxygenate the water. Find a cheap battery operated air pump the easiest, cheapest as long as you have or can get batteries.

    Temperature can be an issue, cheap solution I saw was a blanket with hot water bottles, will need a gas stove. I use gas heaters to keep the room warm, just keep an eye on oxygen .

    That really depends on your system size and number of fish in your system. Heavy stocked systems will suffer due to lack in oxygen a lot quicker than lightly stocked systems. Also depends on your DSB. The DSB will not die at the flick of the switch, but on extended periods of no flow it would suffer more and more the longer the power is out.
    No need to run lights. Maybe a heater on really extended power outs. That is if you got a geni. Do not run your heater on your battery backup. It will drain it too fast. If you have a smallish battery system, just run your return pump. More than enough to keep tank and sump alive. If you got spare battery capacity, then adding one or 2 powerheads to your backup system is a good idea.

    hi

    agree with riaanP

    1) dependent on stocking level, but would say on average 4 - 8 hrs, it all depends on fish only and or coral as well.
    2) I will get worried if it drops fast, but normally 3 degrees becomes worrying. Can monitor and dependant on sixe of tank, can use gas heater, cover in blankets.
    3) I use a inverter, runs 1 x 12 watt pump in tank for 10 - 12 hrs, can add battery if you need more flow. also have a small gen just in case more than 24 hrs. if power off longer than 24 hr I would also run a bttery operted ox pump.
    4)I would add some amonia remover that reduces amonia and nitrits and then when power comes back in a stabiliser to just get water quality up and always good to do a water change if the power was of for an extended periord.

    lighting can days off, pump depends on what you use in sump, wave maker should never be down. It helps provide oxygen and bacteria swim around in the water live rock
    2) what is a dangerous temp drop?
    I would worry to lost 2-3grade down, keep polystrene in your garage when power down. pick up polystrene back,left,right,before and sump too. It help temp slow slow down until power come back.
    3) what is the best tactic/plan/machine to use during a 12 hour power cut?
    Gas Heater and UPS backup battery for wavemaker
    4) is there any recommended supplements to use during power cuts?
    UPS or Power generator

    I'm not Anita but the safety connector is something that enables you to run some of the tunze products off of a 12V battery when the power fails. So when you have power, it will run off of its own power supply which is connected to the mains, and when the power fails it continues running from a normal 12V battery. The safetly connector acts as as a relay and switches between the 220V AC and the 12V DC supply.

    When the power goes off the safety connector kicks in immediately, so you do not even notice, this will enable your pump to keep on running until the power returns.
    You need one electronic TUNZE pump, safety connector, small gate 12v battery and a charger to top-up your battery when the power comes back on. For more info contact me directly, cheers Anita

    I have thought about putting a battery operated air pump on a float switch thats the wrong way around in the sump. When power cuts, sump level rises and turns on air pump? You guys think this can work?
