A few days ago I started the arduous task of getting algae from my pool. It is a common and difficult thing as any pool cleaner and/or owner will tell you. It sounds like an innocuous task but I have learned year after year that it takes hard work, time, and patience to do it. The filter is the biggest weapon. You can put all the chemicals you can buy into your pool and the algae may wane. Eventually however it will come back and usually when you are away on vacation or otherwise unable to offer a retaliatory strike. When you have algae, the filter needs to be cleaned or backwashed. This is the “fish gill” through which the water must pass. It can take 48-72 hours for all the water in a pool to pass through a filter but when it’s clean, boy howdy it really cleans the water. There are other tips I may get into at another time but the universal takeaway is this: Do the big jobs first when they pay the biggest dividend. You can see the top of my filter tank behind me in the photo. That is my biggest wrestling job when getting algae out of my pool.
