Usually when the plunger lines up with the 1. This is fine because the pink plastic tip holds about. When doing the titration, add the reagent drop by drop until you see a color change.
We want to see the exact amount of reagent it takes. A good titration will show an immediate change once the buffering capacity is exceeded. Now to determine what the alkalinity level is, take a look at the syringe and see that the end of the stopper is now at the. Referring to the instructions, we can see that a reading of.
This is a little low considering natural sea water is a little over 8. Before going off and trying to raise the alkalinity levels, consider the appearance of your corals.
If they are doing wonderfully, it may be better to simply maintain the current levels rather than attempting to change them. Also consider that these test kits are not perfect, and also sometimes your technique is not perfect.
Having said that, there are several ways to boost calcium and alkalinity such as additional water changes, kalkwasser, two-part additives, and devices such as calcium reactors. Magnesium can affect the balance of Calcium and Alkalinity and that will be the subject of part III in our chemistry series.
This problematic seesaw effect between calcium and alkalinity stems from how the two ions interact with one another. The two ions combine to form calcium carbonate and fall out of solution, thus lowering both levels.
The first technique is very basic. Water Changes. Water changes help manage fluctuations to a large degree. Most salt mixes available in the hobby today are formulated to have slightly higher concentrations of both calcium and alkalinity. Frequent water changes replenish major elements as well as trace elements. For reef systems that are packed with stony corals, additional supplementation may be required. That brings us to….
Kalkwasser is an age-old supplement that is highly effective in boosting both calcium and alkalinity. Kalkwasser is calcium hydroxide and is considered a balanced supplement that boosts both calcium and alkalinity together.
Kalkwasser comes in a white powder that you mix with purified water. Proper alkalinity ppm or dKH is vital for coral calcification and skeletal formation; it prevents pH swings, alkalinity burn, coral bleaching, and tissue loss; and it improves equipment performance. It is best to test for alkalinity weekly, or as needed depending on your dosing schedule, in order to maintain a healthy aquarium. Simply put, the greater the tank's alkalinity, the greater its ability to prevent rapid swings in pH.
No more guessing at subtle shifts in color! In addition to being easy and accurate, the full line of Hanna Marine Checkers eliminate the hassle of always having to buy new test kits.
When you run low on the supplied HI reagent 25 tests per bottle , just purchase a refill pack and you will be back to testing in no time. The kit includes:. In saltwater systems alkalinity is present in two main forms: carbonate CO 3 2- and bicarbonate HCO 3 -. New customer? Create your account Lost password? Your cart is empty. What Is Alkalinity? Press the button to power the meter on.
When Add C1 appears on the screen, you are ready to begin testing. Fill a cleaned cuvette to the 10mL line with sample and fasten the cap. Using a microfiber cloth, wipe the cuvette to remove any oils or fingerprints from the glass. Then place the cuvette into the checker and close the lid, making sure it is completely closed.
It is important to make sure that the lid is completely closed for an accurate reading. Press the button.
