iron and sodium ore is quite cheap,but why sodium is expensive than iron?
There is a low cost enzyme found in grocerey stores in the USA. I think it is called Rid X. This enzyme eats up solid wastes. Yes it is worth it to use the enzymes.
what can you use to clean out pipes in the aerobic tank
sodium is very likely to bond with other elements (oxygen, chlorine, etc.) this means that it is harder to keep sodium pure than it is to keep iron pure. sodium is very rarely found unbonded to something else, if you keep in air for more than a few seconds it is likely to become oxidized. This means that it will be easier to have iron available than sodium.
Because it's hard to process the Na ore into Na. The process of Fe ore into iron is easier BTW I have never heard Sodium ore? I think that Sodium are made from electrolysis of NaCl
Randys advise is very good I would say the same.
