Overview

Fritz R/O Recharge replenishes essential minerals and electrolytes to reverse osmosis or other purified water to reestablish the desired natural water chemistry for your freshwater aquarium habitat. The mineral salts in R/O Recharge easily restore optimal GH, TDS and KH when used as directed. Our formula provides a beneficial ratio of elements to improve osmoregulation including potassium, calcium, magnesium, and sodium.

Directions

Dose

Add 1 teaspoon per 10 US gallons of RO, RO/DI, or other purified water


  • This dose will increase GH by approximately 100-125 ppm GH and 3 – 4 dKH (60-80 ppm KH).
  • Repeat dose until desired GH and KH levels are reached.

Measure GH and KH levels with Fritz test GH and KH test kits before and after dosing.

Limit change in KH to a maximum of 1 dKH (18 ppm KH) per day when fish are present.
