Advice on Refugium Lighting

[anheezy]

Hi guys! Can someone give me a suggestion or advice on how to darken the inner back overflow area to cover up any light from shining into the DT area from the back? I just purchased a clip on bulb to use a grow light for some chaeto i placed in the media area, but the light shines through the back at night. I'm afraid that it might keep the nocturnal creatures from coming out at night or promote unwanted algae growth inside.

No help with any ideas to darken, but I don't think it would be enough to be a worry... maybe just add a few more snails

Maybe others will have some ideas...

i grow macro in the surface skimmer attachment,gets plenty of light during the day,i dont think a small amount of chaeto would justify a reverse lighting schedule
