Hello,
I am upgrading my tiny reef tank 20 gallon AIO to a 57 gallon, I want to use my Reef Ready rock from this tank and put into the new tank (it has coralline algae growing on it) - I plan on using the same reef ready rock and adding to the large structure on the right and leaving the little structure on the left the same. I used ocean wonders coralline epoxy to make this (I tried using Jurassic gel super glue and failed miserable but the epoxy worked great for me).
So I don’t know if I should just make a larger separate structure for the back or add on to the structure on the right. I don’t want to kill the bacteria or coralline and I was planning on using Marcos mortar this time for a more clean look (the epoxy worked but doesn’t look that great, looks like wads of gum). I have never used mortar before. Thank you for any feedback
