Problems

[Bauyer9]

I'm having problems with my tank and I don't know why! 45 gallon JBJ reef tank. Running for 6 months. I did the usual cycle process, added some fish and coral, everything was doing really well and growing good. A week or two ago I started having major cyano and very minor green hair algae. I've done weekly water changes from day 1. I added an automatic feeder and I'm thinking the tank was getting over fed for a while. A week ago some of the corals started to look bad. Still have color but have shrunk and stayed that way. Zoas look fine, Duncan, birdsnest and one acan all look good. Frog spawn, hammer, not so much. Hammer especially is very shrunk. I've been doing weekly 20 gal water changes. What can I do? Will over feeding cause these issues? How can I bring everything back...help pleaseeee

Yes overfeeding can cause these issues
But your tank is still maturing. You will see the GHA for a while. What is your water parameters and what type of light and your light schedule as well
I have the same tank but I converted mine to have a sump
