Randy and Ryan are annoying. Everything in this hobby is way too hyped. Newbies spend a-lot of money on unnecessary stuffthat is poor design and/or construction. This is the number one reason why people leave the hobby. I wish I could get back the money i spent on items that didn’t last three months. Before someone gives you free advise ask them to show you their tank. That free adise can cost alot in time, frustration, and expensive failures.
Depends on what stuff you pay attention to.
Their 52 weeks of reefing and then their 5 minutes guides are the top 2 best beginner guides for reefing, especially if you don't already have friends in to reefing.
The BRSTv Investigates is also pretty cool depending on what they're investigating. There are certain ones where I feel they're just trying to push a product, and then other ones, like the recent Calcium Reactor video, that will actively hurt their sales, but they pushed the info out anyways.
