you how many watts does your system use?

[John]

Add them up... I want to know who has the most energy effeciant tanks for their overall size.

So...

Watts / total water volume = what I want to know.

If you want show how effecient the tank is at night and during the day.

[rmalone]

Total volume about 200g, 180g with a 100g sump. Tank is mostly sps with one end OWNED by my ridiculous RBTA's.
lights 2x250 halide driven to about 330 watts each and 2x60" t-5s driven to about 110w each
So lights at 880w
Skimmer ATB medium cone at about 60w
Return ATB 1500 flowstar, according to amp draw I would say 90w.
Heaters 4x250w ebo yager, obviously I rarely run all four but it happens in Jan and FEB.
So worst case on heat is 1000w, now that never happens during light on.
I wont even bother with the 1/4hp chiller for now, though mid summer is likely my most inefficient time.

So lets say half the heat 500w
lights 880w
and skim/return call it 150w
So round it all up and I would say 1600w/200g gives 8watts per gallon. But that is just a ballpark and none of us will have consistent energy draw through a 24hr period.

Well before I took my 90 gallon tank down, I had:

Return Pump 154W
Vortec MP-40 x2 56W max
Heater 300W
Skimmer 21W (Warner Marine K2)
Ca Reactor, recirc pump 20W, feed pump 9W
Kalk reactor recirc pump 9W
Lights... the big one 480W (6 overdriven T5)
Sump lights 4x24W T5 96W
Misc other stuff I am forgetting... 100W

For a total of... 1245W

Now, I can tell you that my tank AVERAGED $60 a month on the power bill. Some months a little more, some a little less depending on the temp outside/inside the basement.

Oh, and my display was 90 gallons, with a 30 Gallon fuge, and a 50G skimmer/heater holder.

Accounting for rocks etc, I estimated I had 100 gallons of actual water. Or 12.45W per gallon...

[John]

Alright, I was just doing the math for mine.

DAY
876 - 916

Lights 432Watts
Return Pump 165
2x Vortechs 16 - 56
Skimmer 2x Sicce Pumps - 58 watts
Heaters 3x 250 Watt heaters (Calculated only 215 Watts constant to maintain Temp)



Night
648 - 688
Fuge 48 Watts
Frag Tank 156 Watts
Return Pump 165
2x Vortechs 16 - 56
Skimmer 2x Sicce Pumps - 58 watts
Heaters 3x 250 Watt heaters (Calculated only 215 Watts constant to maintain Temp)



180 Gallon Display Tank (Volume after rocks and sand ~156 Gallons)
120 Sump (Volume after sand and rock and water levels ~84 Gallons)
18 Gallon Frag Tank (Volume ~15)

Total Water Volume - 255

Watts Per Gallon
Day Min - 3.43 WPG
Day Max - 3.59 WPG

Night Min - 2.54 WPG
Night Max - 2.69 WPG

[jolson10450]

for my 29g with a 10g sump, and my 5.5g frag tank, and my 1g micro pico my total wattage of all 3 combined tops out at 350 watts! my combine volume is roughly 35 gallons so total is roughly 10 watts per gallon with everything on.

my main 29g tank is about 250w so judging by total water volume which is roughly 30 gallons i technically use 8.3 watts per gallon on it.

[jimsflies]

My equipment consists of the following...stock biocube return, 150 HQI, MP10, six 3w blue LEDs, 100w (I think...need to verify) heater. Not sure if things like apex controller and osmolator count?

I should be under 300 watts...but only have 29 gallons (actually less) water volume.

[EMUreef]

90g RR with 50g sump maybe half full so will say about 125G total volume.

-2 175w MH - 350w
-2 Koralia evolution 1400's 6w - 12w
-Sicce psk 2500 skimmer pump - 30w
-Quiet one 4000 return - 50w
-heater - 250w
- fuge pump MJ1200 - 30w
-Fuge light LED - 13w

735w day time / 5.88 WPG

[XSiVE]

120g display, 55g sump, 29g fuge, 10g frag tank, probably about ~190g total volume

day usage total: 510W nominal, 910W Peak with both heaters on (they don't run a lot), rounded up to the next 10.
return pump, other circulation pumps & skimmer: 310W
Heaters:400W (two 200W)
Lights: 200W (LED on both display & frag tank)

Night usage total: 300W nominal, 700W peak with heaters.

Day: 2.68W/gal without heaters, 4.78W/gal with heaters.
measured with kill-a-watt

Night: 1.5W/gal without heaters, 3.68W/gal with.

Information

edit: if I calculate my heaters as an average like John did, then I come up with ~120 watts of constant heater so...

daytime: 630W, 3.31 W/Gal
nighttime: 420W, 2.21 W/Gal

[reefdr]

15 gallon Zoa and paly garden, 150w MH and a sub current wet dry filter 20w and one K1 3w. so im at 173 watts :>
