Ska's 28 Macro Algae Display

[skabooya]

Ok i dont know what i was doing yesterday but i think i was typing in 18 instead of .18 or something.
So let me do these calculations online so you guys can make sure im doing it right. Math is not my best subject

Heater 100w
hk1 3.5w
hk2 4.5w
skimmer 10w
lights 160w

the first 4 are 24/7 so i will do them together. they come out to 118watts total divided by 1000 = 0.118kW

then I go 0.118 x 24hours x 0.18 cents x 31 days = $15.80

next: 160/1000 = 0.16kW 0.16kW x 8 x 0.18 x 31 = $7.14

15.80 + 7.14 = $22.94 a month.


That is much better than the $100+ i did yesterday. What the heck was i thinking for those equations? Wow.
