We've had a mild winter here in southern Ohio & so far, a very warm spring: 70 degrees all last week and it hit 80 degrees today! Very unusual for us.
We followed your advice on Closing - to the letter. It was especially helpful with regard to When to Close - waiting for the temp of the water to reach 60deg (if I remember correctly)
In pouring through the posts: Pool Opening, etc. I'm wondering if there is a similar guideline for opening? Since we drained our pool 18-20in below the returns, we cannot measure the temp of the water. In fact, we can't really check on the water at all since we have a mesh cover tightly strapped to the deck.
Here are my concerns: 1) is there a general guideline as to when to open the pool? and 2) with so many warm days recently, are we likely to find an algae bloom if we wait too much longer?
