Just had son check the ph and it's hovering right at 6.8 so I told him to add another 1/2 box borax and check again at 12. At least the ph has stabilized. I am going to by pass the heater since it doesn't work at this point anyway but no bypass I'll have to do some reconnects. As far as the Nature 2 thing it came with the pool and I have never bought another but I will take it out of the system too when I get a chance. How do you add copper and what purpose does it serve? I wish i paid more attention in chemistry class all those years ago!

Thanks
