First I would like to advise you that you will not find an iron content in newly made salted water, it is simply well below the detection level of any aquarist grade test kit available today, normal levels of Iron in seawater are 0.00005ppm. Seachem MultiTest Iron Test Kit – The Aquarium Petshop

This test kit includes everything you need to measure the iron levels of your aquarium water. This is especially important in planted aquariums.
The Nutrafin Master Test Kit A7860 is a comprehensive test kit for both freshwater and saltwater aquariums. This kit tests for 10 different parameters, including phosphate, nitrate and nitrite, calcium, ammonia, pH level, general water hardness, carbonate hardness, and iron. It includes four instruction booklets to ensure that owners perform the tests accurately. The kit also includes test tubes, caps, a spoon, pipettes, and a hard plastic carrying case.
To address your question about iron test kits. I would not go to the length of saying that they are all inaccurate and not to bother with them. As a matter of fact, they can be very accurate as long as they are compatible with the the type of iron you are testing for. There are indeed different types of iron that are supplemented to an aquarium. The 2 main types of iron used in the aquarium are chelated iron and non-chelated (free) iron. Chelated iron is in the ferric state (Fe3+) and must be reduced to the ferrous state (Fe2+), which is the preferred state for plants. In doing this reduction, the plants have to expend a great deal of energy. Our Flourish Iron is already in the reduced Fe2+ state and allows the plant to readily take in the iron almost immediately without using any energy.Testing aquarium water is a key component of maintaining a healthy environment for fish. The question is, what should be tested? Is there a difference between test kits? This list of aquarium water test kits helps sort what to test for, and provides information about what products are available.
In order to provide the ideal environment for your freshwater/saltwater fish, testing the water for accurate levels is key. There are several test kits available to help you accurately measure and maintain the chemicals in the water, but it is just as important to research the recommended target levels. For example, it is recommended that
alkalinity be above 75 mg/L in order to offset the effects of nitrifying bacteria. Since plants need carbon dioxide to survive, CO2 levels differ in plant-only tanks versus those containing only fish, or a combination of fish and aquarium plants. The more you learn about optimal levels, the better informed you are when using the tank water test.

For owners who consistently have issues with managing chemical levels, they may want to consider investing in biological filtration. A good mechanical filter should already be in place to help aid with managing potential toxins in the tank, but the addition of a biological filter takes things further. Helpful bacteria are introduced through the filter, and upon taking up residence in the aquarium, consume chemicals like ammonia and nitrite, effectively helping to maintain the ideal environment in your tank.

You may also want to install a device specifically intended to monitor chemicals constantly, reducing the need to regularly test for them. Seachem Ammonia has a sensor that detects and monitors ammonia, which is considered the most common killer of fish in tanks. The sensor alerting you when levels are increasing well before your fish start to feel stress, and it lasts for over a year. Look for this and all of your fishkeeping supplies online and in your local pet stores.
Suggested Dosing: Plants do best at iron levels between 0.1 - 0.5 mg/L. We recommend you begin with 1-2 drops per gallon of aquarium water, and measure your iron about an hour later with a good quality iron test kit. Initial consumption by plants will be very high, since Yamato Green Fe is in a highly consumable form. You may find that daily dosing is necessary until the plants saturate with iron. After that, 1 drop per gallon, once or twice a week, should satisfy the iron needs of the plants. If you are not using an iron test kit, try 1 drop per gallon, once a week. If plants begin to yellow (chlorosis), add more iron. If algae begins to grow, reduce your dose.
