Found these 20lbs bags of ironite at homedepot for $10, just want to make sure they are safe to mix in with my substrate. Here are the specs::
Urea, Muriate of p0tash, Calcium sulfate, sodium borate, ferrous sulfate, iron sucrate, iron oxide, maganese sulfate, maganese oxide, sodium molybdate, zinc sulfate , zinc oxide.
If i wash it to remove the sodium can i use it?
Also says:
N 1%
K20 1%
Ca 12%
S 10%
B 0.02%
Fe 4.5%
Mn .1%
Mo .0005%
Zn .1%
Some sites claimed that back in 98' this stuff had lethal doses of lead and would leach out arsenic and make the water acidic..... But i dont see anything in the ingredients that would do that since it says guaranteed analysis i would assume they would list any heavy metals..
