Should I use my old rock?

[Fitzy]

Thanks everyone, all great advise. My plan originally was to just swap all rock over to the new tank but I saw a small patch or two of my arch enemy Bryopsis and thought maybe I should just start over. I’m thinking I might build one island of the aquascape with new dry rock, cycle tank, move fish over one at a time, once system is stable move corals? Clean cure old rock to build second island? The biggest drawback is of course starting over and the fact I may add these nuisances right back to the tank down the road. Thanks again for all the feedback!

Totally free of phosphates. I can add fresh reefcleaners out of the box- not even washed- to my tank and it just grows coralline. No weird algae at all. I added a new bridge made up of reef cleaners to my well established reef. A month later this is what it looks like . If it was leaching something, you would see some odd algae appearing typically.

My new 300 gallon is just reefcleaners- thats how much I like it. And I am a very critical person in general. Just no complaints.

Thanks so much, sounds like I made a good choice on rock.
