Florin Delta KH+ – Freshwater Alkalinity Supplement (500 mL)

Increases Carbonate Hardness in All Freshwater & Planted Tanks

• Increases alkalinity (carbonate hardness) in freshwater aquariums with a target pH of 7.8 or less
• Improves buffering capacity and stability of pH
• Safe for use in all freshwater community and planted aquaria
• Made from USP-grade ingredients
• Contains no phosphate-based buffering agents

Brightwell Florin Delta KH+ is an easy-to-use alkalinity supplement for use in all freshwater and planted aquariums. In aquarium care, alkalinity is a way to measure how stable the pH of the water is. The higher the alkalinity, the less likely the pH will change. It’s important to adjust and maintain the alkalinity at the right level for the organisms living in the aquarium to ensure their long-term health. Before using any pH- or alkalinity-altering supplement, it’s recommended to check reliable sources that provide the specific requirements for the organisms in your aquarium. It’s also crucial to dilute the product in water as directed and test the pH and alkalinity with an accurate meter or test kit before adding it to an established aquarium. Make sure to read all the instructions carefully. Additionally, remember to adjust the alkalinity, pH, total dissolved solids (TDS), and temperature of the water before adding it to the aquarium.

*To increase alkalinity in systems with higher pH requirements, the use of Brightwell Aquatics Rift Lake dKH is recommended.

Instructions & Guidelines

Do not add Florin Delta KH+ to an aquarium without first determining pH and alkalinity with an accurate meter or test kit. Read entire instructions before proceeding.

Aquarium addition: Dilute 1/4-tsp in ~16 fl-oz. (or ~500 ml) of purified water and mix well; add the resulting solution to the aquarium at the rate of 1 fl-oz. per 5 US-gallons (18.9 L) every two hours until alkalinity has increased and stabilized at or near the desired level; note that the rate of water circulation in the aquarium will impact the speed with which the active ingredients alter the alkalinity of the system (faster circulation will decrease the time required for alkalinity to change), and that alkalinity stabilization may take up to 24 hours in extreme cases (it is far more likely to stabilize in less than 2 hours, however). Do not enact changes in alkalinity of greater than 1 dKH per hour. Consult a reputable reference for alkalinity and pH requirements of the organisms being housed in the aquarium and make adjustments to these parameters as necessary to attain the desired values. pH may be further adjusted through the use of an appropriate acid or base solution (such as Brightwell Aquatics Florin pH- and pH+, respectively).

Tap and/or purified water addition: Adjust alkalinity of water to desired value with Florin Delta KH+; once alkalinity has stabilized, add Florin pH- or pH+ until desired pH is attained. Finally, adjust TDS of water (such as with Brightwell Aquatics Remineralīz or Remineralīz-P, or with Florin Delta GH+ for planted aquaria), to desired value. When water temperature is approximately equivalent to that of aquarium water, add water to the aquarium.

Caution: Contains carbonic acid salts; do not taste, swallow, or breathe dust, and avoid contact with skin. If swallowed: give water, get medical attention. May cause eye or skin irritation. If in eyes, flush with water for 15 minutes, get medical attention. If on skin, wash thoroughly with water. Keep out of reach of children. Not for human consumption.
