Tried to wait out the pollen and oak tree squiggly things so I waited a little too late to take off the cover. Heartbroken to see some algae forming. Started my slam yesterday and following the directions to a T. It's going great. Hoping I'll pass the OCLT tonight. Amazing how fast the algae eats the chlorine up. Starting to hold now. The send pic is carriage lights the hubs put up for me yesterday.
