Default Acid copper

Congratulations on your 300th posting!
You have been a great help. I am sure some how Mike will find out!
The resistors do get hot. It is hard to find the high wattage ones. 25 watt is the highest I have seen. I will have to order them as my supplier only stocks the 15 watt ones. So now that I have past this hurdle, my next problem is to get the pH down to where they suggest it to be. (1.0 - 2.0) I am at 0.8? Followed all the instructions but perhaps I should have checked the pH as I added the battery acid. instead of going to the quantity in the formula. It does not seem to be building up copper as I had hoped. After flash copper platting a piece of steel, I inspected it and looked great. Scotch brighted it then degreased again and in it went the size was 49 sq" so I set the current with the resistor to 2.5 amps and ran it for about an hour then looked at it and ran it again for an hour. There were just small "ribbons" of copper around the edges. Sort of like small lines. A very cool appearance if that is what you wanted. But I was expecting a little more coverage. The anodes were very dark as well as had a sort of brown film on them. Unlike the flash copper anodes that were very shinney and clean. I am still very new at this, I will listen to any suggestions. Have a great weekend.
Thanks
Brian
