I have read through numerous posts how Indian Almond Leaves can help with water quality. Yesterday, I got my shipment from amazon and wondering how do I use them? Do I crush a few of them and let them settle in Rusty's water or do I place one of them in his tank? Will he get sick if he nibbles at them; thinking it is food? All of you know how greedy our pets can be? Let me know soon. Be safe for those of you who will be traveling soon for Thanksgiving.
