Make the story short, my tank is crash cause I move my tank to my new house. Im trying to re do my tank right now, but iam wondering if I cld just use 50 % from my old tank and 50% of the new water.
Sorry to hear about that buddy. 50% new water change sounds good. Check the parameters and run some carbon to clean out the toxins left in the water column from the dead corals and continue running a protein skimmer. Once the water clears and the parameters check out let me know if you need some startup frags to get your tank going again.
