I’m planning to replace the aquascape in my 240L aquarium. I’ve already built the new aquascape for the left side. I’m keeping the right side as it is, but the left side contains about 80% of all the rock in the tank. How can I do this without killing all the corals? I’ve built the new scape and placed it in a bucket with water from the tank. I have a heater in the bucket, but currently no circulation (I do have an extra pump). Is there anything else I should do? Do I need light?
How long?
