I have a Elos Midi tank with glass sump, I had extra LR that I threw in the sump, I want to make a refugium in the sump to keep the algae from growing all over the LR in the main display. If I put a light under the tank and shine on the LR rubble in sump will this help keep algae out of main display. Will it cause any problems in the sump?
Thanks!
Thanks!
