I was trying to create wet dry action on my tank! So i got 20 of the black rena stars that float on the water, and made a long basket that fits on the 1 foot opening on my acrlic. Then i have all the stars media flaoting on the water in the basket then i have a 1 foot spray bar blowing clean water on them. Is this concept a way to get massive colony of bacteria, since they are getting water and air constantly and they are in the dark.
