I got tigger pods from the fridge at my lfs. Instead of dumping them in i put them in a 3 gallon pretzel jar near the window. Used my tank water and gave them no aeration and add fish flakes every few days. Its now booming with them and i have an unlimited supply to keep adding with almost no upkeep.
I can give you algae from my fuge. There are pods. Reef2go is good too. They have 20% everything. Pods used to ship free but I am not sure if they still do,
