Try the same search criteria if you haven't already. I'd also watch as much YouTube as possible. I like the videos from BRS personally, so I haven't searched for podcasts much before.
How about someone start a show on this forum! It'd be interesting to do, when we have frag swaps.
Reef Threads. I don't to a lot listen to podcasts except for this one (I just recently figured what a podcast is lol). I'm surprised that it doesn't get more attention, it's really good! http://www.reefthreads.com
So I have been listening to the reef threads pod cast. And I have to say. Some are really good and others are terrible. Mainly the guy on the show is kinda hard to listen too. But when they have guest speakers. It is very good
I listen to reef threads at work as well. There was a pod cast called the talking reef back years ago, but like many others it stopped. There isnt many around.
I'm in to star talk because Im into space. Not reef related. Also listen to science Friday, also not reef related.
There is YouTube for reef related topics, but it uses up a great deal of iPhone battery.
