I recently started using the Technichlor SWG. Just curious as who else is using and how they like it. So far, after only a week, it seems to work nicely. Trying to see what setting will maintain a 2-3 PPM range. I am going between settings of 3 and 4 right now with a 395 gallon tub. Any replies on what your doing will be appreciated. So far I think I am going to like the freedom it gives. THX
