still fishing for the best sand size, but once you get it in and established, you want worms. Every spaghetti, tube worm etc you can get your hands on to seed it. In my old favorite tank, when I fed, 10,000 tiny arms came out and cleaned for me.I just bought 200 lbs of sand for my 240g. I have about 80 lbs of Special Grade, 40 lbs medium sized, and 80 lbs sugar fine. I plan on putting the sugar on the bottom and mixing the other two together to add to the top for my shrimp goby/jawfish/pistol to hang out in. When I do a water change I will vacuum just the very top without disturbing the sand bed. What do you guys think?
So I wouldn't vacc at all. good flow to keep particles in suspension is important to get it to the skimmer esp important in the beginning as you wont have worms yet.. I seeded mine heavily from the older tanks.
Yes, I have never thrown sand out. I have the same sand and worm grandchildren from my first 10g.
