OK, definitely understanding this stuff and yes, it is difficult to get it down as the pH range gets closer.

I have my return eye pointing virtually straight up and it creates a serious amount of splash, to the point it splashes out all sides of the pool...so that is sufficient.

I had to go out of town and of course, no one followed my directions and so I went from a pH of 7.2 and arrived home to an 8.0.GRRRRRRRRRRRRRRRRRRRR

So back to the beginning and I will get this TA down yet.

Shoulder? 4 tears averaging 4-5mm each, acromium bone removal, socket enlargement and bicep muscle reattachment...fun, fun, fun. Actually rather have surgery again than deal with this flippant TA!!!!
