Randy or any help here.
We have had a problem since the start of the summer in my area, each of us (around 4) have had reef tanks for many years. This has us stumped, we have stn in our Acros mainly starting with the Millis & tort group, and higher occurrence of cyano bacteria. Two have reported a oil type film on the water, our soft corals and lps seems unaffected by what ever is going on. All testable parameter test fine, and we are all on the same water source but 2 different water companies.
I have tried Carbon, GFO, Phosgaurd(never at the same time and a period in between each product), and changed all my filters/membrane in the R/o unit. My tap tds is around 30-40 and after the 6 stage it has all ways come out 0. I have recently tried the Two little fishes Metasorb with no color change. Today i noticed that my rubber (powerhead to tank mounts) seem to be degrading(when cleaning them black came off when scrubbing, like i was rinsing carbon) I was also able to rub some off my bulkhead gaskets.
We have been experiencing major drought in Northern CA and have been on Ground water for many months now.
SO my question seems to be could it be from Petroleum leeching from the ground water getting through the Ro unit? If so how would one go about trying to remove it? From my quick search it seems like Calcium carbonate is a good choice, so any hard coral would act like a sponge if i read that correctly.
Thanks for any input, sorry for the lengthy post.

Also a few people who live in the same area(some only blocks away) have done little to no water changes and remain unaffected by what ever it is. AeroJet is also a local company that tests rocket engines and has had to do some clean up for the spills in years past and i kind of wonder if they are in part responsible.
