What can I use to have a really clear idea shade of blue in my tank (it looks like the blue sea water)? natural?
my idea mistress aquarium with floating flowers, and the crystal clear what can I add to my bowl? I can only think of rocks, but there's nothing I shinny can also add? Thank you for the help!
Food coloring will work for the blue color. You can also add glass beads or the beach (From a craft store) and shells.
