Ok what I want to do is add a DSB with different algae growing on top of that. My tank is 1.8m X 0.6m X0.6m. tank I want to add is 1M X 0.6X X 0.6m . I want to use play sand and make it 15cm deep. Then grow culiptra and Cheeto ext on that. Maybe put seahorses in there once there is n million pots in. Know can I just add this or will the dsb go true a cycle and make problems? Tank is in my system it is just used as a nennie tank @ the moment.(want to change to making it more of a filter using dsb and algae) Any suggestions?
