What a nice forum!!! Thank you to YOU for reading my boring intro. This will be the third year of my 24ft round above ground pool, the typical 13,500 gallon pool, and my second year opening the pool. I have attached a pic. I have had problems opening the pool the last two years...my winter tarp has failed the last two years which has caused lots of problems. The BBB method is new to me and I'm excited about learning. I would like to post about my green algae problem so if anyone could point me in the right direction I would appreciate it.
