Tie-up using “Splitter”(Pink), and Standard Reefmasters(Green) in a Development End( 7 rows, 6 columns )
Could make “splitter”s By cutting off unused end Pieces(14 off)
Horizontal “splitter” Vertical “splitter”
Make “splitter”s Different colour for id purposes Could vary lower det. to let bottom go off last??
