Red Sea Reef Foundation Pro Multi Test Kit (Ca, Alk, Mg)

Red Sea Reef Foundation Pro Multi Test Kit is used for accurately measuring the levels of Calcium, Alkalinity, and Magnesium in a reef aquarium to ensure the balanced proportions necessary for coral health and growth.

Red Sea's Reef Foundation kit includes high-resolution titration tests for accurate measurements of the elements Calcium (75 test's), Magnesium (75 tests) & Alkalinity (60 tests) which are the basic foundation elements of Coral skeleton's.

All of these elements need to be available in balanced proportions for coral health and growth. This test kit enables accurate dosing of the reef Foundation supplement, which is part of the complete Red Sea reef care program.

Why Test For Calcium (Ca)?

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 the 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).

Why Test For Alkalinity (KH)?

The pH level in a salt-water aquarium is a constant concern to most aquarists. Whereas the occupants in a fish-only system can tolerate a fairly wide range of pH levels for periods of time with no major harm, the occupants of a reef tank rely heavily on a constant pH level in the right range to just survive, let alone thrive. The generally accepted pH level in a basic salt-water system is between 7.6 and 8.4, but reef tanks are more sensitive, and therefore need to be kept at the higher end of the pH scale, 8.0 to 8.4. respiration and metabolic wastes are a natural part of the ocean, but the reason that seawater pH does not change is that the water contains a number of chemicals, such as bicarbonate, calcium, carbonate, borate, and hydroxide, all of which act as natural "buffers" that retard the drop in pH. When the pH in a salt-water system starts to drop, it is an indication that the buffers are getting worn out, and the increase in acidity needs to be corrected.

Why Test For Magnesium (Mg)?

Magnesium plays an important role in any reef aquarium. In addition to its many biological functions, it serves to prevent the excessive precipitation of calcium and bicarbonate, which lowers the calcium level and causes a drop in alkalinity. Magnesium should be maintained at approximately 3 times the level of Calcium, measured in ppm. Corals build approximately 90% of their skeleton by combining Ca and CO3 ions from the water to form Aragonite (CaCO3). The rest of the skeleton is made up of Magnesite (MgCO3), Strontianite (SrCO3), Calcite (a more brittle crystal structure of CaCO3), Fluorite (CaF2), and other minor and trace minerals.

In unbalanced conditions such as low levels of Mg and/or Sr, the skeleton will develop with a higher proportion of Calcite making it more brittle and more susceptible to damage.

Best shoe ever
5 star rating for literally the best shoe ever. I wore these almost everyday this summer. They are so incredibly comfortable. Cushion and padding is wonderful makes walking and wearing them very easy. They are not to platform at all and they don't have a separate heel height from the rest of the shoe so you're on a even walking ground. Size is perfect I stayed true to size and ordered my original sizing in Ugg which is perfect. The style os so trendy and literally goes with everything. I highly suggest them. I have back problems/ back surgery and these made my life so much easier. Comfortable and great support.

Well made sandals
Nice sandal that works well for me, feet sit comfortably in the shoes. I’m a quadriplegic that needs someone to wrestle my legs while putting my shoes on for me. These go on fairly easily. I have short legs and the extra height of the sandals helps to reduce the pressure on the back of my legs while my feet are on the legrests. Also my ankles tend to buckle and cause my feet and shoes to roll over onto the side of my foot. The soles of the UGG Goldenglow are wide and flat, substantially reducing this tendency. As far as comfort and function while walking, I can’t speak to that.

So comfortable but only lasted 5 months…
Size: 9, Color: Sea Salt, Size: 9, Color: Sea Salt
I was hesitant to buy these without being able to try them on, but I’m so glad I did! They are incredibly comfortable. I am on my feet for a large portion of the day as a school principal and these feel amazing all day. They’re very adjustable so if you have feet that swell (or just fatter feet like me) these should be able to accommodate you. They are clunky but really cute! They’re also easy to clean. I’ve worn mine just about every day since I received them and can easily wipe them down with a wet paper towel to make them look new. They will occasionally trip you up if you’re not careful, the same way Ugg boots can do, but that hasn’t been a big problem for me. They’re very lightweight and versatile. Love them! Update: I probably just wore these too hard because today I was walking the school hallway and the shoe just snapped. One of the sides was completely unattached and within 30 minutes they were only on my foot by one strap. Super disappointed!! But I loved them enough that I ordered another pair to get me through until boot weather.

Great shoe, room for improvement
Size: 7, Color: Bison Brown
I wore these to a 2 day music festival and my feet were so comfortable dancing and walking all day. Got a little sore by the end of the night, but the only thing that would have been more comfortable would be athletic sneakers so that pretty good for such a cool looking sandal. Sizing is off tho. I am a 7-7.5, and I ordered a 7. Length wise theyre good, but maybe I have skinny feet because I had to strap the 3 Velcro straps as tight as they could go, especially the heel one. Maybe I would have been better going down a size because I want to have my feet feel super snug and secure in sandals, especially if I’m dancing. But overall great sandals and honestly I’d buy them again

These sandals are massive
Size: 9, Color: Bison Brown
These sandals are super bulky and fit on the larger size. I would recommend tou size down 1/2 to 1 size.
