This gorgonian was flourishing and fine until Wednesday, the extra flow was put in last Saturday morning but the polyps were out and full, Wednesday I did a 25 gal water change as I hadn’t done one for a while because I’ve been trying to bring up nutrients, it’s a 120 gal system, I also changed a clear braided vinyl hose to a black silicone hose which I just saw thread stating that the hose might leak tin into the water?(uncomfirmed) I also have read the gorgonians shed sometimes, any help is appreciated!
Too much flow?
