I plan on using Randy's recipe for iron, (Thank you Randy!) because I'll be using an algae scrubber.
"solution containing 5 g of iron (as 25 g of ferrous sulfate heptahydrate) in 250 mL of water containing 50.7 g of sodium citrate dehydrate" from here http://www.reefkeeping.com/issues/2004-05/rhf/index.htm
After dissolving in water, I want to test each chemical individually for copper. Do you think I can get a good idea if these chemicals are copper free using Salifert?
