Instructions and Guidelines
pH is always lowest a few hours after the main lights have turned off for the evening, and is highest a few hours after lights have been burning during the day. Adjust pH to remain with a range of 8.1 – 8.5 at all times. Before adjusting pH, ensure that the alkalinity in the aquarium is within a range of 7 – 12 dKH (2.5 – 4.3 meq/L). Determine the pH in the aquarium using an accurate test kit or recently-calibrated pH meter before using Brightwell Aquatics pH+. If the alkalinity is below the desired level, adjust this first and then allow 24-hours to elapse before re-testing pH, then add pH+ as directed below. [Alkalinity may be increased by using a buffer-type product according to the directions; again, an accurate test kit (for measuring alkalinity) should be used whenever bringing about a significant change to the alkalinity. Brightwell Aquatics’ Alkalin8.3 or Alkalin8.3-P (powder) are two buffer-type products that may be used for this purpose.]
Add this product at the maximum dosage of 5 ml per 20 US-gallons per 24-hours at the same time each day. pH will generally stabilize within 2 hours following product use, however livestock should not be subjected to a change in pH of more than 0.2 per 24-hour period, so do not overdose pH+. Repeat as needed to attain desired pH value. It is recommended that pH be maintained within a range of +/-0.2 at all times.
