More than 10 years Wright. I heard rumors of it in the 80s in
LA and ignored them even though fish stores had dire warnings.

Then one day (around 86 or so) I changed a bit less than half
a tank of water and watched fish die, nearly instantly right 
before my eyes. I switched to store bought bottled "spring"
water for a short while till I got an RO filter and used half
RO + tap + Amquel. The RO did take it out (or so Ron Harlan
said, and I believe him) but it was too soft, so instead
of loosening up the membrane so it didn't produce as soft
water - which I probably should have done, I used half tap
instead.

I used the Mardel (I think) chlorine/chloramine test strips. Quick,
easy, accurate. Any non-zero reading is cause for concern, no, alarm.
