You have to take into account that Na Hypochlorite contains only half as
much Hypochlorite per Molecule as Ca Hypochlorite, since Na is only 1+, Ca
is 2+. But since NaClO is almost exactly half as heavy as CaClO, this is
countered out again. By my calculation, you'd need 2256 mg/l of your
chlorox. By the way, I'm not familiar with chlorox, is that a cleaning
agent? If so, it will also contain Chlorite, ClO2, and other cleaning agents
and I wouldn't advise you to use it. If it's only Na Hypochlorite and water,
it should work (at least to kill your germs, I don't know if it's dangerous
to the plants and/or future fishes).

An australian source mentions 200 mg/L of 65% calcium hypochlorite.
However I
wouldn't even know where to get that. Regular clorox (Na hypochlorite) is
6%.
What dilution rate would I need to assure I've cleaned the tank - and for
how
long? The australian recipe is 200 mg/L for 1 hr or 100 mg/L for 24 hrs.
I
suppose the simple solution would be 10 times as much as clorox is 10
times
weaker???
