Stuff's going dark/bright purple

[Grayzie]

Ok, so I'm new, just redid my sump into 3 parts to keep water flow level for my protein skimmer, and I used black silicone that I got from my fish guy, so I had to change about 30% of my water while I did it, my salt is a little low, .22 usually .24 and I've now noticed that everything is going purple, from different shades, I'll post some pictures, any help is appreciated, thank you
should be beige, dark brown snail shell, aiptasia

Coralline is Purple and Pink. This what your looking for? I don't see anything wrong there. ??
As far as the Anemone turning colors, ya got something in the tank form using black silicone, thats probably shouldn't be used in a reef tank, and if it is ok to use, you should have left it to cure for 2 weeks before filling it.

it's not coroline, I know what that is, I had a beige carpet turn from blueish to purpleish, and aiptasia's have also had their tenticles turn to a light purple, the silicone is for fish tanks, and it doesn't have to cure for that long, it was hard and I had water in there and changed it, cleaned it out again then returned it into my system, any chance that when I added some of the water fresh water before it mixed could have anything to do with turning anemone's blue/purple, the carpet looks as if it's going to die
