Thanks! I decided to scrap the idea and use the moss in my planted nano.
Although the jars looked real pretty the first few days, muck began to build up inside the jars.. Due to a lack of current running through them.
But this marinade jar idea is inspiring me to drill a few holes on the bottom of the jar too, and give it another shot.. Just to see if there'll be a current this time (and to see if I can avoid the muck).
Thanks for the idea! I'll probably try it out, and I'll let you know if I do.
