I am wondering why it doesn't expand like it does before. Ever since I got my 6 bulb T5 light fixture (1 Geisman pure actinic, 1 uvl 75/25, 1 uvl aquasun, 1 geisman actinic plus and 2 current use stock blue) it hasn't expand or grow. It's shrivel up against the rock. It's on the sand bed right now and just like before, farthest away from light as possible. I like how it look before and want to get it to look that way. Everything else is looking nice and growing, hammer, frogspawn, candy cane, acan, xenia,green star polyp, zoas and polys.
