Why does my LED light unit appear dimmer than when I bought it several months ago?

First, make sure your original light settings have not been dimmed. Next, verify if your lens has any accumulation of deposits (minerals, algae, etc.), which can significantly block light passage. If this is the case, use the Fluval Lens Cleaning Kit (#A3969) on a weekly basis to ensure you are keeping light levels consistent and maintaining optimal conditions for coral growth.
