Last year I posted about the blackbirds/crackles whatever they are dropping there offsprings waste in my pool. Well there back! like clockwork. Here is the link
I have my filter all setup ready to go and the pool is clean now all I have to do is uncover it if we use it and recover when done.
The birds should be gone by late May early June. Is there anything different about the chemicals needed if the pool is covered most of the time?
