Red Sea Reef Foundation A (calcium)

Red Sea Reef Foundation A is used to maintain optimal calcium levels in coral reef aquariums to support healthy coral growth and stability in water parameters.

A successful coral reef aquarium is dependent upon maintaining the appropriate water parameters that in turn provide the stable environment required by the corals. Although all the elements found in natural seawater have an important role in providing optimal water parameters, a few of them have a more significant role in the overall stability. These elements are the foundation of the reef environment and they include the three major elements, Calcium (Ca), Magnesium (Mg), and Bicarbonates (HCO3). These 3 elements have a major effect on the water chemistry (pH stability, Alkalinity, seawater ionic strength) and on many of the coral's biological processes (skeleton formation, ions exchange, photosynthesis).

The foundation elements complement each other in the formation of the coral skeleton and if not available in the correct ratios one of them will quickly become the limiting factor of healthy coral growth.

Reef Foundation A contains Calcium, Strontium, and Barium according to the ratios found in coral skeleton.

Dosage Liquid

1ml will raise the Ca level of 100 liters by 2ppm

Different from the liquid Foundation Program, the powder formula has a much higher concentration.

Dosage Powder

1g will raise the Ca level of 100 liters.

Supplementing weekly - Soft / LPS Corals

Test the foundation elements every week and dose each supplement to replenish them back to the optimal levels.

Supplementing daily SPS / LPS corals

Ensure that all of the foundation elements are at optimal values and run the aquarium for 4 days at a stable salinity (compensate for evaporation daily by adding freshwater) without adding any supplements. At the end of the 4 days, test the foundation elements and calculate the 4-day dosage of each supplement to replenish back to the optimal levels. Add the 4-day dosage to the system. Divide this 4-day dosage by 4 and use it as the daily dosage for the next week.

After a week of adding the daily dosage, test the foundation elements and calculate the adjusting dosage of each supplement to replenish back to the optimal levels.

If the adjusting dosage is significantly different from the previous daily dosage amend(increase/decrease) the daily dosage as appropriate.
If the measured level of a specific element is above the optimal level wait for the excess of the element to be depleted before restarting the daily supplementation with the amended daily dosage.

Continue testing all of the elements every week and make adjustments to the daily dosages as required. As your corals grow or you add or remove livestock the uptake of the elements in your aquarium will gradually change. It is recommended to keep a logbook of the weekly measurements and dosages.

If you miss one or more days of supplementing add the complete amount that you have missed but do not exceed the maximum recommended daily increase for any of the elements.

A fundamental message for preparing the heart, mind and body
Format: Hardcover
"Preparing your heart for marriage: Devotions for Engaged couples" is a great devotional that should be used by certain couples who follow a certain type of Christian spirituality to help prepare for married life. As the author Gary Thomas stresses, marriage is an entirely different ballgame from dating. No matter how long (or how short) you've been dating your beloved, living with them and learning how their personality works in daily marriage life is the key. These are 30 pre-marriage devotionals that do not require a Biblical reading with them, and have questions for reflections at the end. First, the pluses of this book. The black and white pictures and the layout of the book is just gorgeous. This is a perfect gift for a couple who has just been engaged. The preparation for marriage is realistic. This book deals with myths regarding a perfect marriage are, what communication is and how to continue to learn to love the other person even when times are tough (it's called taking your marital vows seriously). Now, the issues I have with the book. There is a big emphasis on being sexually pure before marriage. A lot of people will like this approach. However, some of the most religious people I know don't believe in this anymore, and feel this is a lesser sin. Some people who might be open to Christianity might be turned off by the heavy handiness of this subject in this work. This is a very Southern Baptist approach to sexuality. When I read about the author's credentials (teacher and writer in residence at the Second Baptist Church in Houston, TX which is one of the largest fundamental churches in Tx) I was not surprised by his approach. While I understand this approach and there are scriptural references to this approach, it may not be appealing to those questioning the validity of Christianity or to those who are interested in exploring becoming a Christian. Overall, this is a good gift. My Husband and I are an old married couple by now, and we enjoyed the book together and read it in one sitting, discussing the questions at the end. I think this can be used by older married couples. (We decided to revisit our courting days and asked some of the questions at the end of each devotional in past tense). I note the author seems to have devotionals for married couples and has written 18 other Christian oriented relationship books as of this writing. This is good for engaged or newly married couples who have a fundamental bent, or who are willing to either skip the sexual purity chapters or discuss the importance of sexuality in their present married/engaged life.
