    Hi,
    I have just calculated my electricity running cost per month for my tank...:y1:
    Ouch.....
    The reason for this painfull exercise is the fact that our house hold electricity bill is just HUGE! (don't really want to mention how much...)
    I just want to pin-point where our usage is going to.
    .......
    Now I need some serious help to try to cut on this (the tank's usage)... (not sure one can)
    My total tank volume is currently +-750l (busy pushing it to 900l by adding additional sumps to the setup)

    Calculated per month my cost is between R. 400 and R. 600, depends on how long the chiller & heaters are running. (And I think this might even be on the low side)

    First thing that I want to change is the return pump. It's a Hailea HX-6550 (200 W)
    It's running 24hours a day - thus using 148.8kW per month. Cost: 96.8 per month!
    The problem is, I wanted to add another pump as my flow from sump to display tank is not enough...
    So I'm looking for a bigger pump - using less enery...:whistling:

    I have 3 80W lights - it's only on for about 10 hours - Running cost R. 48
    I can reduce the run time from 10 hours to 8 hours, but that will only safe R. 10 per month. So not really worth it.

    Algea scrubber:
    4 - 50W lights, on for 16 hours per day - Running cost R. 64 per month.
    Pump for the algea scrubber - 100W - 24 hours per day - R.48 per month.

    Chiller:
    480W - I've estimated a run time of 6 hours a day in summer - R. 58 per month.

    Protien skimmer x 2:
    65W+65W = 130W - running 24 hours per day - R. 62 per month.

    And the list just goes on....
    I have not even listed the heaters...which is rougthly +- R. 120 per month we had a couple of cold nights....

    Guys - please any advice on how to cut on this...The rest of the household will auction my tank PLUS car PLUS all my belonings to cover for the electricity bill...

    R 600.00 is low for this size tank. I think you are going battle to get it much lower

    They are very energy effecient...but costly...

    Rather look at it as your membership fees to the reefing club. All sports and hobbies have expenses, some more than others. I have a similar size tank, and as Warren said, R600 is quite low.

    Why not plumb your overflow to your scrubber?

    I feel your pain.
    I decided to start my new house as energy officiant as possible.
    Started with a solar geyser. Going to drop my bill by 40%.
    Then i am going to add LED down lights. I have 80 of them. That is a total of 4000W
    At 5W LEDs total are 400W.
    Jes it is expensive but if you use energy savers at 11W at R44 at 5000H and you compare it to LEDs R300 at 80000H. Thy LEDs are cheaper and more efficient.
    Now to save energy on my tank I looked at these energy efficient pumps.
    Return Pumps :
    1. Reeflo Dart Gold 11800L/H at 97W 3M Head
    2. Reeflo Super Dart 13450L/H at 116W 3M Head
    3. Reeflo Goby Gold 10600L/H at 139W 4.4M Head
    4. Reeflo Barracuda Gold 14600L/H at 166W 4.7M Head
    5. Reeflo Hammerhead Gold 17400L/H at 191W 5.3M Head
    6. Reef Octopus HY-5000W Water Blaster Extreme Pumps (60W) 3.5m head
    7. Reef Octopus HY-7000W Water Blaster Extreme Pumps 7,000l/h (88W) head:3.7M
    I'm going to go for the Reeflo Hammerhead, as i am going to run my entire system on it. So no extra feeding pumps for stuff like Chiller,Calcium,Phosphate end carbon reactor,denitrator ext.
    Yes it is very expensive but as i mentioned withe the LEDs. In the long run it Will be worthwhile.
    I am also going to add a huge fan to help with the cooling and the chiller just for backup.
    Still don't have a answer for the lighting.
    See if you can get your hands on a bubble blaster skimmer. at 60W they skim like no other big ones can.
    And i only use tunze. Expensive but last forever and very low on feul.

    Have coupla fans blowing at scrubber as well to reduce chiller usage.
    User 23W energy savers for scrubber lighting instead of 50W, works for me

    Reeflo - ?
    Where can I get some prices on these?
    If you say expensive - in what range are we looking at?

    True, BUT with this more volume I get extra filter capabilities PLUS the more water volume the more stable the water parameters which includes the temperature.
    I'll insulate a bit better...


    I'll sell my left kindney first - interested?:lol:

    U could try and run your scrubber outside using natural sunlight.

    I'd agree as it is the logical thing to do, but having had the gravity fed scrubber myself, I can tell you that you have countless problems with humidity under the tank causing electrical problems. Aside from that there is the real risk of blockages in the spraybar.

    im in the same boat and im renting so i have had a few encnters with the landlord over this issue.. my main consuption was my cls and return being on the most, i am looking at a simular pump to schaun to run everything with a second vortech to assist in flow variation.. my lights are on for a limited time each day and i have taken my chiller off but will have to put it on now over summer as i lost all my sps 2 seasons ago through water temp rising too high..

    its not a cheap hobby but as pointed out well worth it in comparioson to other memberships you ywould have had to pay for with less rewards...

    I'm thinking of insulating all 4 my sumps, the back of my display and maybe the sides of the display tank with polystyrene....
    (still thinking about the side panes, the position of the tank only allow partial view on side panes in any case..)

    The heaters and chiller will/should work less not so?
    But by what degree?
    How much temperature escapes thru the glass (night time and winter months)?
