I currently test for:
KH hardness, Calcium, Ammonia, Nitrate, Nitrite, Iron, Phosphate, and Ph.
What other tests should I be doing? Iodine, Iodide, Copper, other elements maybe.
Thanks.
i don't test for iron, but iodine is a good test. i don't think i'd be too concerned with testing for copper and iron on a regular basis. perhaps during a cycle, to see exactly what is in the rock i have in the tank, but i don't think there will be a buildup of either of those in a reef setup over time.
