Hey everyone. I have learned a lot about the salty world. My tank has been cycling for a month almost. Ready for stock but have a few.questions. I have a aquaclear 110 20 lbs live rock 20 lbs base. How often should I change filter media? Just picked up a hydro korlia 750. Is this enough or do I need 2? Also where should it be placed? Stock questions any advantage or disadvantages going.peaceful or predator tank. Looking to go coral down the road maybe a year. I know this is a lot any help would be great.
