you don't think that had anything to do with the cat peeing in it do ya?
this is one area where me and Brad disagree (not to often you'll find that) but I think it was more a problem with the depth and the bottom areas of the sandbed becomming septic and causing compounds that would not normaly be formed in a non septic enviorment to leach back to the water colume. by reducing the depth you get rid of these septic areas and thus no bad stuff.
I don't think Brad can say for sure it was because he put new sand in or because he reduced his depth as the sand he had in there had contaminated stuff from another source
so he never tried just reducing the depth as he HAD to replace his sand.
Dr ron's original theorys were good and work in the Ocean but even he admidts that in the hoby we only have 1 or 2% of the different types of critteres needed to make it all work properly, and for the past few months he has been backtracking on his whole sand bed theorys and trying to blame everything else like heavy metals and different brands fo salt for the sand bed failurs that were set up to his method.
