I got a biocube of fb marketplace. It came with the viparspectra 165w. Seems like a great light. Currently I have my blue lights on level 20 and my white light on level 9. Seems like a really strong light for a tank this small, and I've read to keep it low. I only have one zoa frag in the tank so far. It looks good, but there is one polyp that doesn't open all the time, and I am wondering if that's because of my light. So I wanted to see if anyone had good advice for what settings to put the lights on
