ya. i think so too. but the problem is i couldnt get the fresh dry rocks either. in that case, i need to make diy base rocks using cement and it took me 3 months to cure them the last time i made those. thank u for ur advice though. i just happen to live in a country where the reef keeping hobby doesnt suit very well.
Wow, I just now saw which country. Boiling for several hours outdoors away from people is the simplest. Just don't forget that everything in the tank needs some sort of treatment or you will put the cleaned rocks back in and suddenly you will have aiptasia growing on them again.
Namaste.
