^^ it's ok, I don't like reading old posts from long back either.
25lbs liverock, I recently crushed up the most dense so I can maximize my surface area. I replaced my ceramic pieces with the crushed liverock
Fluval 305 canister filter
82 degrees F
1.023 specific gravity
While I put the liverock in my filter ( in 1.5/3 trays, the other 1.5 trays is the carbon material in the bags) I also did a 15% pwc
What I mean for starting over, remove rock and replace shells with sand (figure its better to do this during the cycle rather than after), pwc
of atleast 30-50%, than put another shrimp in.
Btw I use distilled water with red sea salt, distilled water is easy and most practical for me atm.
