Overflow covered from the lights

Over the past two months, I've watched algae grow in the overflow. Since it is lit from the metal halides above, a cover was needed. Now that the fifth and final Durso was installed, the cover could be fabricated and placed over that area.
I decided to make the cover big enough to cover the entire external overflow and overhang the teeth a little. It had to be drilled for the Durso caps, as well as for the Aqua Controller probes.

And finally a close up.
The probes are visible from the front at the moment. ORP and pH. The temperature probe is behind them 4" away.
I'm still going to have to clean out the overflow to get a nice fresh start, but I'll let the stuff weaken in there for a day or two first.
