being very new to this, i've decided that i need more live sand after my tank is up and running. it was an established tank when i bought it and all i did was move it. i left all the existing filter media so it would cycle better. it no longer has any ammonia or nitrite. the problem is that i have 4 chromis damsels and i'm afraid i might hurt them by adding the sand now. any suggestions?
