Their storefront is called Socal Tropical Fish in Fullerton. I went there a few weeks ago. It's not a bad store I guess. They have quite a bit of frags although to me the variety of SPS frags wasn't that impressive at all. They had quite a few nice designer clowns including midnight clowns etc. Decent variety of fish and acans and stuff like that. Store was pretty cluttered and dirty to be honest but I'd shop there if I lived in the area. It's just that there were piles of dirt and stuff that was swept and never picked up. There was random stuff all over the store like baseball gloves and tools etc. I felt like I was shopping for coral in someone's garage. But the owner greeted me right when I walked in and seemed helpful. If you're in the area I'd recommend dropping in.
I also went to Reef Raft while I was in town. This place is pretty awesome. The guys who worked there were both helpful and kinda cocky at the same time. Not obnoxious or anything. They have TONS of frags. Lots of acans, chalice etc etc. They also have a lot of nice SPS frags. Not a huge selection necessarily but just hundreds of 3/4 to 1" frags. Prices aren't a steal or anything but you can put together a pack of 5 for a decent price. They have pretty much zero fish so if you're looking for new fish for your tank this isn't the place. But if it's a few nice colorful frags you're looking for this place is definitely worth checking out.
The last place I checked out was Discount Tropical Fish in La Habra. The owners are older Asian folks and they were really friendly. Especially the man. They've got a pretty decent selection of fish, some common zoas and some corals too. Nothing rare or exotic here but a nice clean shop.
