Make sure u have enough buckets/ or storage bins that can hold water, u realize how little buckets/ space u have until its too late then ur running around. Id also get some tough gloves, you know the ones that go up to your elbows (purple in color)? you dont want to grab a rock and get stuck by a bristle worm, or cut your hand and get an infection, these rocks have alot of bacteria on them/ in them. protect yourself. if you have zoas/ palys especially, they can poison you if you touch them with your hands alot. You dont want to suffer side effects of palytoxin for 2-3 weeks because you picked up your favorite zoas by hand.
