Hi,

presently, changing the water is a PITA, because of placement of the tank (I don't have that much space where it is now) nearly on floor, and the drain is of course the lowest point. When I manage to put it elsewhere, it will not be such a big problem. It is interesting to know if the silver buildup on bottles with old fixer is sufficient to act as biocide. Chlorine bleach probably the easiest way, it's "brute force" and working well :) But I was a bit afraid of trying it because of JOBO's warnings. What if the whole tank melts ;)
I don't think the tank will melt; more likely, it will, over a period of time, become brittle, weak and liable to fracture under the weight of water or a processing tank. If the bleach is very diluted, the effect should take much longer to happen. OTOH(s) the dilution may then be too much to prevent formation of whatever it is and the process of degradation may be one that self promulgates once started.
