How's the tank and those fry coming along?

That is the most magnificent piece of wood I've ever seen. *snicker*
Seriously, love it.

Hey thanks for following - The tank is still doing well, though growth is slow.
The light is on hold as my bulbs have not yet come from china. *shakes fist*
Also, I didn't even think of the beam narrowing due to the refractive boundary of the water / air. Good call.

Re: Bogopolis - 30g w/ 20g sump (Pic Heavy)
Just an FYI on the optics, a 45 degree optic is rated for 45 degrees before a 50% loss. In all my fiddling, this usually makes a 45 degree optic much closer to a 30 degree optic in terms of real output. The path becomes even more narrow when it hits the water. You should be fine with those 45s.

|tropicalmackdaddy||Any updates on this tank?|

To get the spread I'd like and the mounting height, I'd have to go with 30 degree optics:
The fixtures I'm currently sourcing have 45 degree optics, which gives me about 130% coverage at the top of the aquarium
Image shows 30 degree optic spread at 1.8'
And 45 degrees
The 30 degree optics would offer better penetration and less spillage, but may burn plants near the surface. Refractive index is not taken into account either. Spread at the bottom of the tank would be less than is indicated.

Found a source for 12W GU10 LEDs. To start, the fixture would be a mix of cool white and warm white. Eventually I would like this to be digitally dimmable, allowing for a sunrise / noon / sunset effect.
I may disassemble the lights and add RGB components if the CRI proves to be poor.
Here is the preliminary design. 1x4 and 1x2 construction. 28mm hole saw for the GU10 sockets. Total cost $40

For this video I used Corel power director. It's very easy and intuitive. I have used Vegas in the past and liked that equally. Really for a video this simple (audio track + fades) any of the available packages would have been suitable.

|RobMc||Thanks. I have very minor algae issues, generally localized to decaying leaves / wood. After very heavy feeding, or when the rams decide to dig up the grass. -_- I do get a little growth on the glass. Under normal circumstances the floating plants in the sump keep the water column nutrient level very low and I hardly ever have a nitrate reading. I attribute this to a higher uptake than production rate. Npk is removed from the system by literally pulling out 2-4 handfulls of plant growth from the sump each week. Growth is directly related to how heavily I feed and the rams' nesting behavior.|

|samee||Your pro with the camera!! Also, what program did you use for the video? SonyVegas?|

|SlopTank||That's some heavenly video dude, very nice. Ever bump into any algae issues with the window?|

|RobMc||Down to just 3 youngins, but they're looking pretty good. Hoping at least two make it out of the woods.|

|bitFUUL||Diggin' the video, very well put together.|

That is an impressively nice setup. Totally digging the plumbed driftwood idea.
I just read from the beginning. If you decide to de-rim your tank, its easily done with a good sharp utility razor knife. No dremel required. I think that tank rimless would take it to another level.
