    Hi

    Can everyone please comment on their backup systems and well as any ideas that you may have in regards to backup systems in keeping your tanks alive in times of black outs?

    I want to put 2 of my powerheads in the display(pointing upwards to agitate the surface) on a Inverter with a 102AH battery to keep things alive, would this suffice it should last a long time as the pumps pull max of 10W each?

    This will be running of a relay so even in my absence will be able to function. Genny is out of the question.

    or just take the day off and use a straw to blow into the tank to agitate the surface;)

    Your Idea will work fine

    I currently run only my return pump & a heater with an inverter & 2 x 105amp/h Batteries

    that way no part of the system is with out oxygen.

    Dymax has a AC/DC airpump but I'm battling to find out if the pump runs full time or if it only switches when power trips, does anyone know? They're about R600 I think

    After going through 38 hrs with no power recently I would do the following. Run ether your return pump on a inverter to keep the flow throught the whole system or if you cant do that then depending on nthe size of your tank ether 1 or 2 power heads but I would run atleast 1 of them with a ventury to supply air aswell.

    Battery operated air pumps from Resun that come on as soon as it "senses" no 220v AC or Boyu submersible air pumps running of 12VDC

    I use a small little power box, with 2*12V batteries, same as in you Centurion gate motors and in your house alarm. Shoebox size. Perfect for nano's, complexes etc, no ventilation issues or noise problems.

    Running a 12V 1.9Amp 1900L/h bilge pump. Pumping from return chamber to tank. So all my water flow stays as is, sump, tank, overflow, to scrubber, to sump.

    Power trip, and its goes. Tested it already for 5.5 hours. After that I swap the batteries with my house alarm and gate motor. Another 5.5 hours later, then I have to swap with neighboors, brother, father-in-law... whatever. But longest down time I ever had was 10 hours.

    Sure, it is at the moment at Lanzo. He want to test it and see if it is worthwhile to sell. Price should be under 1500 for everything except the flexible tube from pump to tank. Just a 3 part box, plug it in, other side connect pump. That is it, power trips, pump goes on. Power back on, it recharge. Want more than 5.5 hours, add another box with its battery. Watch this space. Saved my tank during a 10 hour power break.

    I did show it at 2 or 3 of the Pretoria get together's in the beginning of the year. The guys were impressed.

    Riaan, do you have a separate inlet to the tank for the bilge pump (ie 2 return pumps, one for when power is on and one for when power is off) or are you using it as your normal return pump as well, just connected to a DC source permanently?

    Bilge pump is separate. Normal bilge pump as used on boats to prevent you from sinking if something goes wrong. But those pumps are not designed to run 24/7. But they push 1900L/h for 1.9amp 12V. Supposed to save you and your crew from deep water until you get to land. So yes, two return lines. One for normal return, when power is on, and another for bilge pump on battery pack when Eiskom decides you must be load shedded.
