How long does this last before it needs to be replaced ?
The package says "up to 6 months".
But I think the under water thing may speed up it disolving.
I think I should also add that because I only have 10g tanks with few plants that I actually think would benefit from it I only use the individual beads pushed down into the sub/w tweezers around each plant that I want some around.
The shortest distance between any two points is a straight line...in the opposite direction...
