Backyard Aquaponics
A place to discuss aquaponics

can't say i've ever seen it! I have a yabbie or two in my aquariums, and currently have about a doz. in one. interesting..................

There are a stack of barrels at our tip that my brother was thinking of getting. Used to contain Silver nitrate cystals.

Leave them there or bring them home is the question?

make up you own mind.

a few point i thought of after reading that.

i doubt that well washed drums will contain more than milligrams of AgNO3

is is used in babies eyes just after birth

may have an inhibitory effect on bacteria

if you are asking if I personally would use them? Probably.
