Over the last few months, I've been working on my new and final tank, meaning I will not upgrade to anything else. Anyways, my aquascape is finished and I've began to fill the tank with salt water to submerge the dry rock. I'm planning on just running the tank with a powerhead without doing any top off or running the sump since I'll be gone for a month and a half and just want to start the cycle and realized I will probably come back to a lot of algae. My question is, I wanted to put some live rock from my mature tank. There is a bunch of coraline, some nice starfish living in the rock, pods, etc. The only problem is, I realize that I'll be getting bad things too, and one of those is possibly some flatworms. I first noticed the flatworms all over a frogspawn and dipped the coral killing all of them, but noticed them again in the back chamber (sump) of my nuvo fusion. Is there a way or eliminating these things off of the couple rocks I chose to temperately put into my new tank to help cycle? I heard fresh water dipping will cause them to explode. Also, How many times should I dip my corals to make sure nothing bad carries o the new system?
