Long story short, 32 gallon biocube with Steves LEDs upgraded lighting - stock hood still on. ~ 2 1/2 years in and things are going well. 5 fish and a good mix of soft, LPS and a few SPS corals (montis and birds nests). Noticed today that lights are not coming on. I've reached out to the light manufacturer but no response so far. I'm leaving in 3 days and will be out of town for the 3 days following so I'm short on time to find a solution. Question is this - how long can I go with no light and the corals be ok? (It is next to a window I can open so it wouldn't be totally dark, but its not direct light by any means). Other question is, If i need to open the hood and put a temporary light over it, what is a quick way to make a screen so I don't have any fish jump out? Thanks in advance!
