Here is a link on discussion of zeolite
http://www.ultimatereef.net/forums/s...d.php?t=267358
In every paper I have read zeolites are marginally effective in marine tanks. Also I have wondered if this stuff can be recharged in marine setups. When I used to run FW, to recharge zeolite I used a saturated salt solution. Which is contradictory to use in marine tanks.
Anybody want to add to this discussion?
