didnt really have a drip sort of setup so i just set the bag in the water and every so often let just a touch of water in...it worked well the feather duster just jumped out as soon as i unwrapped it all happy like lol... bear in mind this is my first live thing...its not in my large tank, i put it in my live rock tank that i have seeding the lace rock i got. My parameters have been steady and good so i figured hey might as well try something small and so far so good!
