I will use dry rock in the main display. True ocean live rocks from the ocean are not available here, but there is this store that sells wet dry rock which they left in a tank that they ghost feed all the time and those rocks also have copepods on them. I can use this but I am afraid that the copepods will not survive the cycle and that they will not have any food during the cycle. Live phyto is not available here. Or else I will just use bottled bacteria. Also um do you think that the bacteria from the rock and the copepods would eventually make it into the display tank if I only put the rock into the sump and not the display tank? Do let me know! Thanks!Don't cycle with fish. It's cruel, and it isn't even the best method. Real live rock from the ocean will have you cycled in a week or so. If you don't want to do that, dose bacteria and ghost feed. It'll take a little longer, but it'll work.
