The point of having a large tank means you have more rock which means the pods have a lot of great places to breed without predation.
I don't agree with people saying that you can have a large tank without any pods... You may not see them, but I can guarantee if you've ever had more than a couple pods in your tank that you brought in on LR/chaeto your pod population will explode in a very short amount of time with no predators.
Brine shrimp is not the answer, either. A diet consisting of adult brine shrimp would be like you eating rice cakes your whole life. Besides, its not guaranteed your mandarin is going to eat them.
