So the design is the first design that I've posted some time back. Basically one inlet and one outlet. The inlet leads to a first chamber where I planned to put wool and bio media. Q1. What bio media should I use fir this 1.6L compartment? I planned to fill it up with water, run the pump and check for leaks. If there are no leaks, I'll proceed to add salt. Get it to the right salinity then let it run a bit more. Q2. What salt to use? After that, I'll get live sand and live rocks to do the landscape. Q3. If I get cured live rocks, can I get put it in tank since there's no fishes and corals in there? When I settle this part then I'll get the Tunze 9004 skimmer and the IM max Reactor mid size.
