I used vibrant knowing it was a 50/50 with corals and whatnot. I used it around 4 or 5 hours ago and every coral looks fine except my 2 rbta. They are totally closed and im not sure if i should be worried or not. I dosed 8ml when i shouldve dosed 10ml because ive heard of many bad things happening and that sometimes you can just dose less. Should i be worried?
