Squirt Posted June 10, 2012 Report Share Posted June 10, 2012 After looking at Seachems Nitrogen, it contains Nitrate and ammonium. After looking into it a little more, ammonium can be used in aquarium fertilizers. But clearly ammonium isn't good for fish (which I won't be stocking) so that is not a worry. So I have found a product in the form of sulfate of ammonium (which I assume is (NH4)2SO4) So clearly the ammonium will be used up by plants and the sulfate ions will be left. Is there any side effects of sulfur(sulfate) on plants? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted June 10, 2012 Report Share Posted June 10, 2012 I use it as a nitrogen source on the compost heap but don't know about aquarium use. Quote Link to comment Share on other sites More sharing options...
Squirt Posted June 12, 2012 Author Report Share Posted June 12, 2012 Does anyone know what form of phosphorus would be in this? http://www.tuigarden.co.nz/superphosphate 9% phosphorus 11.5% sulfur P=31.0 MW S=32.1 MW Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted June 12, 2012 Report Share Posted June 12, 2012 It is basically bird droppings reacted with sulphuric acid and other bits added including Mo, K, B, Ca, Mg, and Se. There is a heap of stuff in there that you probably don't want in an aquarium Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted June 12, 2012 Report Share Posted June 12, 2012 If you react sulphuric acid with bird poos you get sulphate of potash (pottasium sulphate) Quote Link to comment Share on other sites More sharing options...
