Agree on vast majority of YouTubers.BRS Videos and articles, anything printed on the bottle of a supplement or product, ICP testing and chemicals rebranded for reef use. Most folks with YouTube channels. Build threads where people show me boxes, unboxing and routing cords and stuff.
It's usually just an attempt to shill products from manufacturers that endorse them.
