Reef Chemistry Question of the Day #211
Which of the following additives would be expected to chemically reduce the ORP of a reef aquarium? Assume each one is only what is says it is, with no impurities, and is added in amounts reefers might typically use. List all you think will reduce the ORP. By "chemically reduce" I am looking for a pure chemical effect, not one that, say, relies on organisms to use the chemical and reduce ORP through other processes they carry out.
A. Calcium chloride (common calcium additive)
B. Ferrous gluconate (e.g., DIY iron using Fergon tablets)
C. Lugol's Solution (iodine supplement)
D. Sodium carbonate (alkalinity additive)
E. Sodium bicarbonate (alkalinity additive)
