'Cause I had a commercial acrylic bubble
tank that was used for years without problem.
Then after switching to CuCl (regenerated
with 40 weight H2O2) it crazed and went
brittle in about 6 months.
I now used HDPE and PCV and neither have an
issue. Some builds even had ABS parts in them
which I thought would be marginal, but seem
OK.
