Hi,
I'm looking for alternative sources for the EI salts and wondered if any of these were suitable...
500g Mono potassium phosphate - fertilizer high grade! (£4.49)
http://www.amazon.co.uk/dp/B00AU6MAAW
1kg 1000g Saltpetre min.99.8%-assay! Potassium nitrate (£6.99)
http://www.amazon.co.uk/dp/B010GB4GWA
1kg Magnesium Sulphate food grade! (Epsom salt) organic 100% pure (£3.79)
http://www.amazon.co.uk/dp/B00VPITEU8
P+P for the lot would be £12.50 - and I think I'd need to get the 'Chelated Trace Elements' from APF or similar.
I think there is money to be saved, but unsure what is 'aquarium safe'?
