Switched all the leds to run 700mA and boy this thing is bright, probably pushing it now. Will have to slide it back when the algae comes :P
Modded both powersupplies now and replaced the stock fans with 120 mm Noctua fans. Thing is dead silent when the fans activate, really nice. Had some noise coming from an inductor belonging to the driver running the violet LEDs that had a cracked casing/shield, resulted in some vibrating noise when dimming. Dripped som thicker type supeglue on it and the sound went away as the glue got hard.
Going up too 700mA on the leds sure resulted in some additional heat making me wonder if a heatsink this size is pretty much necessary for this much light, at least if you are gonna run it passive. At 300mA the heatsink felt cold to the touch but now it is slightly warm to the touch on the fins. Somewhere around 40 degrees C (104 degrees F).
Going through my first day cycle now, starting with a morning period that is slightly dim and has a slight green/yellow tint with a touch of red. Pearling from the plants during this period were moderate.
Now it is in the late stage of the midday cycle and man the pearling is crazy. Coming from everywhere and FINALLY my Micranthemum 'Monte Carlo' is pearling (and the pearling is goooood). Also the first time I see my Alternanthera Reinecii variants pearling. Turning of the pump for 5 minutes and just watching all the bubbles raise up in a straight line is so friggin calming.
Feels good getting some sort of confirmation on the build resulted in something better for the tank.
Currently the controller is fetching the weather from Manaus in Brazil. A City right next to the Amazon River which is kinda cool. It is partially cloudy today, kinda nice with the cloud effect in the tank.
Only negative I have right now is the 3000K leds in the back. It is a tad to yellow back there. Will probably replace those 4 leds later with something a bit cooler.
Also now during the midday cycle I noticed the Angelfish and tetras being a bit lower in the tank, still not hiding but not acting like they used to. Might be to bright in the tank or they just have to acclimatize to the new light. Kinda hard to now where to draw the line where it gets to bright for the fish. Rest of the tank inhabitants do not seem to care, minding their daily business.
