Seems you are pretty new to marine aquarua...
If I may offer some advice...
Slow way down. Everything with this hobby is deliberate, well thought out and executed. The faster one goes, the closer to disaster they come. Knowledge is the key to successful marine keeping. Hind sight is a sure fire way to fail.
One thing you should consider doing, and will allow you plenty of time to read...order your hard goods, filters, powerheads, test kits, etc...online...most instances you will pay a fraction of the cost then purchasing locally. And while you are waiting the 3-5 days for your goods to come in...read and read and read somemore.
The issues many will express concerning Beaslbobs methods are not so much geared towards his methods, but the manner in which he pushes or tries to push them off on beginners. Marine fish keeping is a very trying at times type of hobby...one screw up and your tank could be dead with all inhabitants dead as well. Marine aquaria is far less forgiving the freshwater. Ideally, a newcomer to the hobby should focus more on proven methods of aquaria keeping...once established and knowledge level has increased...then the newcomer should start venturing into unorthodox ways such as beaslbob does.
Do a search for NM Reef, you will see what a nice tank looks like compared to the picture above...
