Of all the facets (to put it nicely) of marine aquarium keeping that turn off hobbyists, likely none surpasses dealing with pest algae. Normal maintenance of our systems can be a breeze; not taking much time or physical exercise, given that time in investigation and proper set-up has been accomplished. However, run-away algal problems can be proverbial plagues... not only ugly to even smelly messes, but a root cause of livestock malingering and loss. The purpose of this book is to share with you how to avoid pest algae problems; and if they do occur, how to identify the source/s, the algae themselves and effectively solve (reduce to eliminate) noisome, unwelcome algae from your tanks.
