Just wondering what the highest level you can swim in. I have been keepping my level pretty high 10-20 while I have been sorting out my pump and filter issues. I have them running now, although there is an underground leak which is a matter for another thread. My water is clear and all my other chemical levels are in rhe recommended ranges according to pool math. I will probably use my scuba mask just because I will have my contacts on.
