Use filtred and boiled water or Aqua Dest. Before, however, changing over the
water source you must throughly clean the Nova.
The slimmy stuff is bacteria growth. Since the Nova can withstand the use of
Clorine bleach I'd use 1:9 or 1:10 of "household" clorine bleach (as sold in
supermarkets) and let it soak for 1/2 hour or so. Following the use of the
bleach you need to rinse, rinse, rinse, rinse as its a bleach and you don't
want any to mess with your prints.
You may have spores in your water supply and tank and to tackle this you want to
use some anti-algae and sporacide compounds. They are available from multi
sources including home and garden as well as photographic and offset printing
industry suppliers. I use some products from Shamrock in Holland.
