Basic Pool Recovery Chemical Kit (for Sand Filters)

So you come home, and realize the pool is green. First you would use the shock. This will kill all the algae that is present. Next, you will notice the pool water turns cloudy. This is because dead algae consists of very fine particles which will be held in solution when stirred, and settle on the bottom when undisturbed or very low water movement. The problem with dead algae is that it is so fine, that it will be impossible to net out, and often pass directly through even the best of sand filters. This is where your floc comes in handy. Put a tablet or two into the pump basket. The tablets will dissolve a form a thick layer over the sand in your filter, which basically provides a better membrane to filter out the ultra-fine algae particles. Keep the pump running, and stir up the algae so it’s not sat on the bottom. Eventually the cloudiness should disappear. If not, repeat the process until it does Needless to say, if you let your chlorine levels drop and suffer from an algae outbreak, you will know what a pain it is to recover. And this is why we use algaecide in addition to the chlorine. So now would be a good time to give the pool a 6 month dose to stop it happening again. Back-washing your sand filter frequently might also help during this time. Whenever dealing with algae, always remember also to brush the walls and surfaces thoroughly, and be generous with the shock. Shock dosing the pool on a weekly basis is also a good idea, if you know there will be a day where you do not plan to use the pool.
