I have this beautiful Scoly that I have had for about a year and all of a sudden it has started to retract. I need a little help where to start please. I haven't dipped yet ( wasn't sure if I could at this point ) around 120PAR and my entire tank is growing and looking great other than a little high phosphate. Tank is about 12 years old. Have some hair algae ( I have a refugium as well ) where should I start to get you guys some more information? Thanks everyone!
