I got a sebae on thursday and it looks fine during the night but about 4 hours after the lights come on it starts to shrivel and stays that way until a few hours after lights go out. last night I think it started to return to normal before the lights turned off but its shrivled right now. I dont think the lights are too strong theyre only 250w and its over half way down in the tank. The only other thing I can think of is pH, I dont have a very good test kit but it shows around 8.5 during the day, I havent checked night time yet. I dont think the swing will be very big because I have a refugium. Other parameters are nitrates >10, phosphates >.03, dkh about 11.5, temp always around 78, and I use 2 koralia 3s for flow. Any ideas?
