I started tfp when we got our above ground pool a few months ago. With a chronically ill child who also has severe eczema, I need help. Lil man's skin looks awful because he wants to swim daily when not at Dr's. And if I skip a couple days of testing the pool water because we're at these appointments, I come home to a green pool. Please help. Should I just bite the bullet and switch to one of the chlorine free systems everyone keeps pushing me towards? I'm so confused.
