Sharks arrived  in good condition from the transport from Maryland. Returning the sharks to wild after out growing there aquariums.

Stability is a major key to success in a reef aquarium. Regularly testing your water parameters is one of the most important things you can do to ensure tank conditions remain stable

The most important conditions to monitor are:

• Temperature: 78 to 82 degrees Fahrenheit is generally considered ideal temperature conditions for a reef aquarium. There are many ways to test and monitor temperature. Electronic controllers and digital or liquid thermometers are most common.
• Salinity/specific gravity: put simply, salinity is how much salt is in your water. For a reef aquarium, specific gravity between 1.025 and 1.026 (34-35 ppt salinity) is recommended. Use a hydrometer, refractometer and/or electronic monitor to measure your salinity.
• pH: Measured on a scale from 1.0 (acidic) to 14.0 (alkaline), pH is the measurement of free hydrogen ions in water. The pH in a reef aquarium should be between 8.2 and 8.4. Liquid or dry tab test kits and electronic monitors are available for recording pH.
• Ammonia/Nitrite: Both are toxic, especially ammonia, to aquarium livestock. These parameters should be kept at undetectable levels (0) and monitored using liquid or dry reagent test kits.
• Nitrate: While it is generally not considered harmful to fish, moderate to high levels can cause significant problems with invertebrate and lead to problematic algae growth. Keep nitrate levels as closes to zero as possible. Use liquid or dry lab test kits and electronic monitors to keep a watchful eye over nitrate levels.
• Phosphate: Phosphate is another fuel for algae and can also inhibit the ability of corals to utilize Calcium in water. Testing phosphate is usually done with a standard test kit (liquid or dry labs), but Photometers provide more accurate results.
• Calcium: Calcium is the building block that comprises calcareous organisms in reef tanks. Calcium levels should be kept around 350 to 450 parts per million (ppm). Numerous test kits are available for measuring Calcium. Most use a titration method to determine Calcium levels.
• Alkalinity: Higher alkalinity deters rapid pH changes and can directly effect Calcium levels. Most reef aquarium hobbyist recommend alkalinity levels between 8 and 12 dKH. Measurement is most commonly done using inexpensive titration of color change test kits.
• Magnesium: Magnesium levels should be about 3 times what your Calcium levels are. In natural sea water, Magnesium levels are around 1285 ppm. Testing Magnesium is also done using a titration test kit.

Here is a movie of the sharks being loaded and heading south for release. Video is at utube linked http://www.youtube.com/watch?v=ZUjGXRXw-uQ&feature=youtu.be

This rock is full of holes and crevices mostly all calcium carbonate. Stacks real easy with the interlocking edges fish love this stuff with so many places to hide and swim through.

Fancy Honeycomb

This is some nice pieces of   premium coralline live rock which is excellent for marine aquariums.

                                                     This is some of the best seed rock I have ever seen full of holes and almost pure calcium.

The live rock this summer has lots of marine plants on the rocks and will stay through the end of the year now.

This can sometimes  be mistaken as a aiptasia which it is not .This is a Sponge Anemone  order Actinaria. It sometimes is transparnet or translucent brownish tentacles marked with white bands and speckles. Oval disc brownish translucent with white speckles, occasionally has white center around oral opening. These are associated with sponges and grow from folds in the rocks and cracks and holes .They don,t reproduce quickly like the aiptasia does . And can grow up to four inches across and five  inches tall.
