Adjustment Dosage: Shake well before using. Begin by measuring the alkalinity of the aquarium water and determine how much you wish to increase it. Each mL of Pt 1 will increase the alkalinity in 1 US gallon (3.78 L) of water by 2.1 dKH (0.75 meq/mL). One teaspoon (5 mL) will raise 10 US gallons by 1.06 dKH (0.38 meq/L). Do not exceed 5 mL per 10 gallons daily, and always avoid an immediate +/* 0.2 change in pH.

Routine Dosing: 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 (1tsp) each of Pt 1 and 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.

• For best results, add RPM Elements to a sump or high flow area of the the tank
• No equipment restrictions necessary
• No contraindications: can be used with all of our other products and meds
• Safe for invertebrates
• Easy measuring: the 4 oz, 8 oz and 16 oz bottle caps are approximately 5 mL volume; 32 oz bottle caps are approximately 10 mL volume
• Some cloudiness is normal. Allow cloudiness to dissipate completely in between adding Pt 1 and Pt 2
• Overdosed? Observe livestock for distress, perform small water changes if needed
• Test for alkalinity with reliable alkalinity test kits

NOTE: If magnesium levels are too low, 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.
