Vanson Sea Klear Phosphate Remover is the only one we Recommend.  We have tried them all and this one is more powerfull and works in the water.  What we mean is other brands work in the filter and you add the product to the skimmer. With Sea Klear you add directly to the pool, spa or fountain water.

Note:  Phosphates are the nutrients for algae. They are found in fertilizers and approximately 150 different sources.   If you have algae you have phosphates. Just using chlorine or algaecides will kill the algae but not the problem.  Many Pool Store are not up to speed on phosphates or removal.  To insure a worry free pool use a phosphate remover weekly and you will not get algae. Get your phosphates checked at least monthly or buy a phosphate kit.  You can see them in our maintenance section under test kits.  Please call us if you have any questions.
