Chemistry isn't my strong point so could do with some advice. I'm trying to source some mnso4 and can get hold of Manganese II Sulphate Monohydrate 98-101% ACS. 250g including shipping will cost me £17.
Alternatively I can buy 50g of Mn 13% EDTA Chelated for £4.99 including delivery.
Are these chemicals similar just with differing Mn contents. Is the cheaper one suitable for aquarium use?
Last question if the 13% edta is suitable how many milligrams would I need to add to a 500ml solution to generate a strength of 0.02 ppm per 60mls dosed in a 240l tank.
Hope the above makes sense.
Thanks.
