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.

Good product, decent stick
it's okay. The first night I had it on my monitor one of my cats yanked it down somehow and after that it lost all it's stick entirely. I was upset about it at first but after some hardcore taping it seems to be holding up just fine. The sticky parts that it comes with don't seem to be as strong as I thought but It's not too hard to fix and the headphones stand part itself is fairly well made and a good space saver. Overall I really enjoy this purchase. I do think there's room to improve on the hold and stick to the monitor, but it's so nice and convenient to have my headphones off my desk space completely that I'm willing to MacGyver the hold to make it work.

W Monitor Stand
I’m using this on a Gigabyte M28U, and it works really well for keeping my headset off the desk and making my setup look clean. The mount itself is made of plastic and holds the headset securely with no issues once installed. That said, this is a pretty specific fit situation for this monitor. The top of the M28U just barely fits the mount, and the slight curve at the top makes installation a bit more difficult than expected. The adhesive strips appear strong, but I had to hold it in place for about 5–10 minutes in the area where it wasn’t fully sticking so it could properly bond to the curved surface. Also, I’m not totally sure if it’s just this monitor, but once the headset is on the mount, it leans slightly toward the side you place it on. It’s not a dealbreaker, but it’s something I noticed depending on how the weight is distributed. My only suggestion is that it might be better if the mount was made from a slightly flexible metal or material so it could gently bend and better conform to curved monitor tops. That would make installation easier on monitors like this. Other than that, no complaints. Will update if it fails, hoping it doesn’t lol

Sleek and sturdy, conforms well to most monitor backs
Very sturdy, no flex or sag when hanging midsize DT 900 Pro X. Applied well to my curved monitor back after prepping the surface with isopropyl alcohol. The 9 different mounting points give a lot of flexibility and conform to the monitor shape. Great value considering it saves space on my desk, lower maintenance; does not need dusting like a separate stand. The headband pad is very soft (silicone?) with gentle curve that should not leave sharp indentations in headband. I do wish the headband pad were a bit longer for hanging the headset cable when not in use.

Space Saving Headset Stand
Needed a headset stand that saves space, perfect for my gaming setup. Glue strips are holding up so far.
