Is there an algaecide dispenser

Answer 1

Well...yes, but not in the way you are thinking. Let me explain. The algaecides you are thinking of (Linear quats and Polyquats) that are sold in the quart containers are not meant to be added on a continual basis. They are meant to be added once a week, several ounces at a time. They are good at preventing algae. But what most folks don't know is that chlorine is actually what kills the algae. The algaecides simply help it along. They strip the cell walls of the algae and allow chlorine to do its thing. And of course, there are chlorine dispensers for the tri-chlor tablets. Even though you didn't ask -- the best algaecide is Polyquat. Usually the larger stores like Walmart and Kmart don't carry it, since it's more expensive than the linear quats. However, polyquat is more effective and it has no side effects. It also acts as a clarifier. Cheapest place to buy Polyquat is from intheswim.com or lesliespool.com, it's generally sold by the name "Polyquat 60" or "Algaecide 60". A quart runs about $20. The linear quats (the chemical name begins with the word "Alkyl") are okay; but they foam. The other type of algaecide that is effective is Copper. Algae can't grow even with a relatively small amount of copper in the pool - but I don't recommend copper. It can (and will) stain concrete pools, and it can turn blonde hair green. In fact, if you have enough copper in the pool to kill algae, you probably have enough to stain blonde hair. So stick with the Polyquat algaecide.
