Got talking to a lad who saw one of my arduino threads and hes copied the design heres his build so far
Stock photo showing the cheapo hood and stand (I actually hate this tank, but try to work with what I have). The stock hood (made out of brown plastic / acrylic) holds up to two small fluorescent fixtures about 20 inches long each) I immediately replaced it w/ a glass canopy and some t5’s. So awkward to work with this stupid thing….
The photos above of the different lighting were taken over two years ago. Lights were on timers. Actinics first, then 2 hrs later the t5’s, and the Moonlight was on an automatic 29.5 day lunar cycle. The eventual brightening and fading of the Moonlight (and its shimmer effect) is what got me going on this whole LED project. Even though there were only three 1/4 watt LEDS, they were certainly the most pleasing to look at.
LED layout (which has changed a bit from layout in photo). OVERKILL? LOL I want to control each color individually and come up with the right mix. The Mega has enough PWM pins to allow me to do this. I will just have to alter your program accordingly.
18 CREE XP-G Cool Whites
9 CREE XP-E Royal Blues
9 CREE XP-E regular Blues.
2 CREE XP-E Royal Blues for Moonlights
3 UV-A LEDS 400-405nm
1 RED LED 660nm
AND (4 CREE XP-G Cool Whites & 1 CREE XP-G Neutral White in the SUMP – Chaeto shall love it!)
And this is what I’ve been working on for the past month or so. (Photo taken with phone, kinda blurry…) Here I have the heatsink (actually two bolted together, with one of them cut at an angle) attached to the partially completed pine hood I constructed. The compound angles can be a pain in the you know what to work with. I incorporated a removable lid for access to the tank…
