I woke up this morning to a freshly filled HOT tub!   

The Metal Gon went in yesterday.  I think I am supposed to run the filters, then rinse them to remove the metals that they trapped?  Yes/no?
My TA is at 200 and the ph is 7.8.  I know I am on the high end.  My experience over the last 4 months has been that my ph dropped and dropped and it was all I could do to keep it above 7 for the last 2 months.
Here is what Doc's site says:  
The acceptable range is 60-180 PPM. If below 60 PPM, add Spa Up until a reading of about 100-120 PPM is reached. If above 180, add Spa Down until a reading of about 120-140 PPM is attained.I am so close to the top  of that acceptable range--both with the TA and ph.  
My Calcium is about 180.
Can I just let it be and let the dichlor bring it down on it's own?  I am thinking that a couple weeks shouldn't hurt anything, but would like some guidance.  Thanks!
