Merdav, personally I would stay away from those chemicals. they continue to build. A small bottom aerator would be perfectfor your detritus control, and be very attractive in your pond. The UV sterilizer will eliminate all the algae and other parasites and bacteria that are floating in the water without harming the beneficial bacterias on debris and anchored surfaces. The UV light with a small water pump will be far more effective, safe, and most inexpensive route to get to your goals. You could install a very effective system for under $100. Your water would become crystal clear for fish viewing, yet have the benefits of an outdoor bacteria colony to control detritus and ammonia. From what I read in your posts of goals is that you want a very large and extra beautiful aquarium.
