How does the gravity feed work for a calcium reactor?

Hello,

You place the reactor below your display tank, and run the siphon line up to the display tank. Then water from the display tank will push its way into the reactor due to gravity.

Problem with this is if you place your siphon line too low into the display tank and the power goes, you may have a flood (slowly but in time) by overflowing your sump.

This is a better way to do things than using a dedicated feeding pump IMO. Just a more KISS approach than the dedicated pump method. Though an even better way is to have it self siphon.
