Oh yea I had about forgotten about that. I went and looked at them again and after 2 months submerged in the different juice, Still the only change at all was the one in my tap water. the others look just fine. and on a side note My alum end caps on the "Gummy tank are now in daily use for about 8 months (un-anodized, bare alum) no visual signs of any problem
PS all my drip tips are the same too. I'll post this also over in the original thread even if it does mean starting it all up again.
It's the liquid that counts that must be tested here, I too have now put some liquid in 3 containers made from Aluminum with 3 pieces of different types of aluminum in each container 2014,6061,6063 and am also doing a test, especially since there are numerous different types of aluminum out there and also it is being taken granite for that what the material is that people are using is the good stuff, none of it is good in my opinion unless double or tiple anodized if it's touching liquids. I want to learn how to identify different aluminum so we know what is what compared to what we are told is being used, its a lot of reading but anyway Gummy is helping the community and sending these liquids off to be tested and that's big to learn what is in the liquids after being in this aluminum for a long time.
Gummy I would think it has been long enough and you could send those liquids off now, know one is going to leave liquid sitting in a PV for more than 3 months how long has it been now ? Also obviously there are many different Aluminum's out there on the market, what TYPE of Aluminum are you conducting your test with Gummy? I forget what you told me or if you ever did because there are so many different types as below.
