I’m setting up a larger
HOB refugium. I have some sand in my current mini-one, but it’s honestly only about a ¼ of the sand needed to create a proper sand bed in the big one. My question is what should I use to fill in the sand for the large
refugium? I obviously plan on using the live sand in the mini-fuge I have already. But we’re talking about adding about 10 additional lbs of sand. If the 10 lbs is LS will that cause an
ammonia spike and mini cycle? Should I use just plain sand and let the 1 pound or so of sand I have seed it? What should I do? Keep in mind that it’s going to be introduced into the tank right away. My tank is only a month old.
