Just found red algae (bacteria) in my pool - have started the SLAM process - shocked to FC level of 20 (CYA=40) and am continuing to add chlorine until the 3 criteria are met. Pool ladder was covered with red slime so removed from pool and sprayed with chlorine solution - also floaties. Solar cover has been off of the pool during this process. Wondering when it is safe to place the solar cover back on the pool? Also, will the cover re-infect the pool with red algae? We will be gone for about 1 week beginning Thursday - not sure if I should replace the solar cover on the pool or leave off. Any suggestions or recommendations are appreciated. Thanks in advance.
