This does NOT cause Algae in a Reef Tank!!!

Algae taking over your reef tank? Your lights probably aren't the real problem. www.reefrookies.com One of the most common pieces of reef keeping advice for algae, cyanobacteria, diatoms, or dinoflagellates is to turn down the aquarium lights or shut them off completely and perform a blackout. While reducing light can temporarily suppress photosynthesis and nuisance growth, it often does nothing to correct the underlying cause. In this video, we break down 5 common causes of algae problems in saltwater and reef aquariums! We'll also look at why algae can affect nitrate and phosphate test results, why biodiversity and grazing pressure matter, how source water can contribute to nuisance algae, and why proper flow is an important part of maintaining a healthy reef aquarium. Then we're getting into the science of reef tank lighting and photosynthesis. We'll talk about chlorophyll, blue light, white light, lighting spectrum, PAR, photoperiod, and why simply turning down your white channels isn't necessarily going to solve an algae problem. Can excessive reef lighting contribute to algae growth? Absolutely. But, when your reef lighting is properly configured, it's time to look at what's happening inside the ecosystem instead. The goal isn't to create a reef tank where algae can't grow. The goal is to create a balanced aquarium where algae can't take over. If you're battling green hair algae, turf algae, cyanobacteria, diatoms, dinoflagellates, or another nuisance organism in your saltwater aquarium, this video will help you look beyond the lights and start identifying the real cause.
