Good stuff bro. Keeping the sand bed clean is definitely something best started early on.I made up a DIY gravel vac - was pretty easy to put together and works like a charm. You can see it in my build thread here -> https://www.reef2reef.com/threads/j...jebao-slw-10-added.679219/page-4#post-7408001
I also stir it around every other day or so and my sand stays pretty darn clean that way. Not all that tough to keep it nice and bright!
