I got a very small frag of sun coral today, two small heads. When I got home I noticed the frag has hair algae on it, along with 1 bubble algae. I put it in a container with one red tip hermit crab to eat the algae. The thing is. My tank is 75 gal, all DIY rock I made. I used dry too. Since I didn't use any live rock is there a chance I could introduce GHA into my system? My tank is very, very clean. I'm thinking of not putting the coral in. The bubble algae fell off so I got rid of it. Would any of you chance it?
