I've always liked to dose ammonium sulfate as N source to my planted tank. every time i dosed ammonium solfate (analitical reagent purity if it matters) . recentley i stoped cause some of u guys warned me that it could cause fish death and algae . when i opened the last copy of TFH i saw seachem add with "florish nitrogen" and it says that it contain some ammonium. it even states : "it provieds nitrogen in both nitrate form and the plant-preferred ammonium form.... "
so my question is who is wrong ?- me and seachem or the guys who warned me no to use it. :?
i must state that from my experience in more then 4-5 different tanks with different species of fish and plants (a lot of them are "difficult" and "sensitive" plants) i never had any problem due to ammonium solfate dosage.
need advise of someone who tried it himself and found that ammonium is more problemtic element that nitrate in the planted well CO2ed and well lighted tank.
anyway im going to use it again and let u know my results on the different species of plants
thanks.

thanks tom , my next question is how can i trust a experiment on elodea when i grow other very very demanding plants?
elodea grows in a bucket of cold water like weed and on the other side eusteralis is very demanding plant that even with the correct water parameters and good fert's a lot of people cant grow it...
