THE Worst Reef Tank Pest I've Ever Had (Cotton Candy Algae + Red Flatworms)

Every reef tank disaster I’ve dealt with started the same way, and this tank is no exception. In this video, I share a full 2025 status update on my 17 gallon Mangrove Reef Tank, covering what’s working, what’s breaking down, and where things are heading next. This system has evolved into a dense macro-algae-dominated reef, but that growth also brought two serious reef tank pests that many hobbyists dread: • Cotton Candy Algae (Red Algae) • Red Flatworms I break down what these pests look like in a real, established nano reef, why they are difficult to control, and the practical plan I’m using to deal with them. This is not a quick-fix video. It’s an honest look at pest management, risk tradeoffs, and long-term planning in a small reef system. I also talk through my 2026 plans for this mangrove tank, including whether this setup still makes sense, what changes may be needed, and how current problems are shaping future decisions. If you’re dealing with algae outbreaks, flatworms, or struggling to keep a nano reef stable, this video shows the reality of managing pests in a mature reef tank and how to think ahead instead of reacting.
