Farming th9 dark elixir!

[Supreme Leader]

Hi guys! 
Wondering if any of you can help me! I'm currently a maxed th9! Just waiting for haste to upgrade and all my troops and spells are maxed! 
Both my heroes are lvl 15! Wondered if any of you had a good way of gathering dark elixir more than gold and elixir! 
Any help would be appreciated! Many thanks!

I farm about 190k Dark elixir in 1 week...
Just use wizards and giants in attacks set speed on 7 and uncheck deploy near red line and collectors
make sure you check the option (attack dead bases only)
see if it works for you.,
