Reefann at the moment i still have 5x400 watt 6500k halides supplemented with 4x140watt phillips o3 actinics. I will upgrade sometime. But that has taken a backseat to the Gallonage upgrade. After i finish doing some work in the attic, for my dear wife, i am converting 2.6 mtrs of my garage to be a filtration/tank room. I will be adding on 3x1000 ltr tanks, one at a time. Which when totally on line will give me a total gallonage (british) of around 1350. And instead of changing 90 gals a fortnight, i will change 250 every say 5 to 6 weeks, it will be so much easier. Also my noisy skimmer can go out there as well as my ca reactor. The water has to be pumped 15mtrs to my garage, and return under gravity. My wife has given me her blessing for the work :lol: :lol: :lol: :lol: 8) I'll post some pics, when i start the conversion, hopefully in the next 6to 8 weeks.....GT
