I just wanted to share that my 300 gallon reef is now illuminated by white and blue L

I just wanted to share that my 300 gallon reef is now illuminated by white and blue LED's. Over 300 of them all of them each at 1 watt output. Replaced about 1200 watts of metal halide. Practically no heat, the light quality has set the corals off and running. I wish I had done this earlier, but these high output LED's were too expensive. I had a guy on the west coast build the panels, they did not come from the aquarium trade, but they work perfectly. Highly recommended as my chiller hardly ever kicks on now and I am saving loads of power.

Here is a link to a Googe page where I will start uploading images. When I service the tank next, I will shoot shots of the LED array.

Before I changed over to LED, I had a heat problem and that seemed to cause a Green Bubble Algae attack. That seems under control now, but getting rid of these has been a challenge since my tank is over 32" deep.
I have devised something that I think can kill them using laser light one at a time. My theory is that if I can hit a bubble with a short pulse of blue laser light, I can cause the interior to boil, theoretically killing the spoors and destroying the bubble. As I am an engineer, I have access to such things and safety goggles. Testing will be on bubble specimens in a small test tank first. Will just corral the fish away from the action area for the real operation. Will post results.

That will be interesting to see. How about using a video camera to record the results? Just know that if you break that bubble you will be spreading those spores everywhere over the tank.

The key to the algae is to try and find the source. Perhaps the lighting was the source of yours and they will clear up in time themselves.

Oh yea, your tank does look nice! I guess you are one of the lucky ones with a flame angle that leaves your coral alone

The tank is L shaped and wraps around a corner. The reef is built up on the corner so that the fish can actually get out of view of each other. That has reduced fighting and seems to keep the fish interested as it must seem like a bigger environment to them. The Flame does pick, but he is looking for Copepods, which I have in abundance. If they hit a polyp, it will retract and then come right back out. I have seen this on real reefs before and it seems as long as the angel doesn't concentrate it attacks and the tank is big enough, the coral doesn't seem to mind. The Black Tail is actually rougher on the coral than the Flame is.

The bubble algae has stopped growing, but isn't going anywhere fast either. I think the laser will kill the spores as well as the parent, we will see.
