    RPM Elements Alkalinity

    Calcium Buffer System Part 1

    For Saltwater
    Maintains proper ionic balance
    • Highly concentrated carbonate alkalinity
    • Great for dosing systems
    • Same high-quality ingredients as RPM Premium Sea Salt
    • No unnecessary trace elements

    Overview

    Maintaining proper calcium and alkalinity levels is essential to a healthy, vibrant marine aquarium. Fritz RPM Elements Calcium Buffer System (Part 1 Alkalinity, Part 2 Calcium) allows aquarists to maintain these two critical components in their proper ionic balance. Unlike other similar products, Fritz RPM Elements do not contain unnecessary ions and metals, which can accumulate over time and lead to toxicity in the aquarium. RPM Elements Part 1 (Alkalinity) is formulated to provide the highest purity carbonate alkalinity, and when used in conjunction with RPM Elements Part 2 (Calcium), along with regular water changes with a high quality salt, will provide the correct ionic balance necessary for healthy and beautiful fish, corals and invertebrates.

    Guaranteed Analysis: Alkalinity (min) 8,000 dKH

    Ingredients: Deionized water, Sodium bicarbonate, Sodium carbonate

    Directions

    Adjustment Dosage:

    Shake well before using

    Measure the current alkalinity (KH) of the aquarium water using a test kit such as Fritz Alkalinity KH Test Kit

    Determine how much you wish to increase the KH of your system, use the dose calculator to determine total dose amount.

    If fish are present and total adjustment dose is more than 0.5 mL per gallon, dose 0.5 mL per gallon per day until full dose is complete, reaching your desired KH level.

    Monitor pH closely when adjusting KH. Do not exceed 0.5 mL per gallon (5 mL per 10 gallons) daily, and always avoid an immediate +/- 0.2 change in pH.

    Routine Dosage:

    Shake well before using

    Before beginning routine dosing, adjust the alkalinity to within the range of 8-11 dKH (2.8-3.9 meq/L).

    Once alkalinity has been adjusted to the desired level, recommended starting dose is 5 mL (1 tsp) each of RPM Elements Alkalinity Pt 1 and RPM Elements Calcium Pt 2 per 20 gallons of aquarium water per day.

    Maintain alkalinity between 8-11 dKH (2.8-3.9 meq/L) by testing daily and adjusting dose accordingly.

    Depending on the degree of calcification occurring in the aquarium, dose may have to be significantly increased over recommended starting dose to compensate for daily consumption.

    Dose

    Each 1 mL per 1 gallon will raise alkalinity level by 2.1 dKH (0.75 meg/mL)

    One teaspoon (5 mL) will raise 10 US gallons by 1.06 dKH (0.38 meq/L).

    Test alkalinity daily and adjust as needed.

    Notes

    If magnesium levels are too low (our recommended range is 1,300 – 1,400 ppm), the addition of calcium and alkalinity supplements will simply result in the chemical precipitation of calcium carbonate. Adjust the magnesium concentration first with Fritz RPM Liquid Magnesium before adjusting calcium and alkalinity.

    • If using with a dosing pump system, stagger alkalinity and calcium doses at least five minutes apart to avoid precipitation
    • If using in a dosing reservoir, stir/shake product occasionally to avoid sedimentation
    • Store in a cool, dry place. Keep product tightly sealed.
