For a marine aquarium the general rule of thumb is one to one and a half pounds of live rock per gallon of water in addition to one to one and a half pounds of live sand/crushed coral/other live substrate. just make sure to let your live rock cycle and add fish slowly.
To determine how many gallons of seawater will be displaced when 200 pounds of live rock is submerged, you would first need to know the rock's density. Generally, live rock has a density of about 0.5 to 0.8 grams per cubic centimeter. Assuming an average density of 0.6 g/cm³, 200 pounds (approximately 90.7 kg) of live rock would displace about 30 gallons of water. Therefore, when submerged, around 30 gallons of seawater will be displaced from the 135-gallon reef tank.
A reef-like ridge of rock is called a "barrier reef." These are found offshore and run parallel to the coastline, providing a protective barrier from the open ocean.
Reef can be a noun or a verb. An example of reef as a verb is that someone can reef a sail by folding or bunching it up. Reef is a noun when used to refer to an underwater rock or ridge.
Sand and rock.
Depends on the height of the room, how many windows and doors, if you use a primer, if it is bare sheet rock and how many coats. You need to be more specific.
It depends on what your trying to accomplish, what your going to be keeping in it, as well as the material of the tank itself. Glass or Acrylic. You can have a Fish Only system, FOWLER system, or a REEF system. Reefs are the most expensive and will run around $3,000 for a 55 Gallon set up Makesure you focus mainly on 5 things in a reef Aquarium and they are... Water Flow Lighting Protein Skimmer Berlin Style Open Sump Large amounts of live rock (1 - 5 pound/ Gallon) FOWLER (Fish Only With Live Rock) Is cheaper and will run about $1,500 for a 55 gallon Set up. Use ½ - 1½ pound live rock/ gallon Fish Only, can go many ways, you can have a cheap hang on back filter or canister filter (Not recommended) or a below the aquarium Wet/Dry filter (Best Option). For a 55 Gallon set up maybe around $600 -$800 without a protein skimmer, though it is BEST if you do get one.
Reef gold is found in calcified objects or rocks. Reef gold was the gold that most gold miners found in rock form.
Captain James Cook is the famous explorer who described the Great Barrier Reef as a "Coral Rock." He first encountered the reef in 1770 during his voyage along the eastern coast of Australia.
Coral reef.
it is a REEF
The larger the tank, the easier it is to maintain. So if you are new to this, stay with the 55 gallon, research a lot, and be patient with saltwater aquariums.
