Millettia Pods

Millettia pods are a nice flat botanical. They are beneficial for their tannins (recommended to lightly boil first. 
The longer you boil, the more tannins you will lose. It I'd also a great place for the growth of biofilm. 
They have many nooks and crannies so that there is always food that only baby shrimp can get access to eat.
Boil 5-10 minutes before use, the longer you boil the more tannins you will leech out. (they may tint water slightly but tannins are beneficial for all aquatic life) 
Measurements: each pod ~1.5-2" long
Quantity Options: 5 Pack, 10 Pack
