Hi my tank had a problem with high phosphates and low ph, i have done a water change to try and help. I added a finger coral 4 days ago, but it has never looked good it has never "stood up" it just looks lifeless. I guess the low ph or high phosphate hasnt helped, the coral looks limp, and my candy cane coral has a little of its white skeleton showing. I take it the chemistry of the water being slightly off is my problem, Should i remove the coral or will it recover?? I dont want to be too hasty on taking it out im hoping the water change will help. Again im new to this and am still learning so advice would be great.
