gedsta,
i know what you mean! It all adds up! You want it the best it can be, but youhave to draw the line somewhere as far as what you spending!
Well, the leds should save you some cash in the long run! Lookign forward to the new pics!
I did some workings out for the cost savings. (I had an ATI unit before the Rads)
Running costs over 3 year Radions / ATI Unit
£1199.98 + £87.36 + £87.36 + £87.36 = £1462.06
ATI: £543.92 (purchase) + £218.40 (electric) + £218.40 (electric) + £218.40 (electric) = £1199.12 + 8 x New Tubes (average £21) £168.00 + 8 x New Tubes (average £21) £168.00 = £1535.12
So its nearly 3 years before the savings would kick in. However, I have them now so I am saving this amount on electricity immediately.
Quick calculations re electricity savings whilst running these.
Radions cost per day 24p
ATIs cost per day 60p
Radions cost per week £1.68
ATIs cost per week £4.20
Radions cost per month £7.28
ATIs cost per month £18.20
Radions cost per year £87.36
ATIs cost per year £218.40
NB - These are over estimated for the Radions as I only have them at 70% for a few hours per day, and sometimes they are at 2% intensity as they go into Moonlight mode. Therefore they probably cost about £80 per year maximum to run as I am doing. Good times.
Some piccies
I upgraded from an APF600 to an APF800 skimmer
