A few quick questions ...
• As I read more and more of these 'tank build' threads, I'm learning that most people put a sheet of foam between the base of the aquarium and the top of the stand. Is this for shock absorption or to level out the surface? I didn't use any foam between the stand and tank - any detrimental effects this could cause?
• I have yet to buy a refractometer but do have a hydrometer. At first the hydrometer wasn't overly accurate, but my LFS
told me to float the hydrometer in the tank for 24-hours. Being a new tank and all, I have been having my LFS
test the specific gravity of my water a few times a week and my hydrometer is now remarkably accurate. How the heck does floating it in the saltwater affect the hydrometers performance?
Thanks for any insight!
