A few facts about my tank

Ingredients:

50 gallon glass tank, crushed coral chips, coral sand, coral, miscellaneous shells, rocks, and marine salt.

Equipment:

Underwater gravel filter system, two submersible power heads, two overhead filter systems, one submersible heater, hydrometer (measures the salt content of the tank).

Fish:

One medium Yellow Tang (Surgeon Fish), two small Electric Blue Damsels, one Black & White Damsel (Convict), one Dot's Damsel (Domino).

Invertebrates:

Two Red-Flair Scallops, one large Feather Duster, one very small Feather Duster, three medium Salt Water Snails, ten very small Hermit Crabs, one medium Free-standing Polyp, two pounds of Living Live Rock (one with several--around 50--small Green Polyps), one medium Chocolate Chip Star Fish, three medium Peppermint Shrimp, one small Rock Anemone.

Specifics:

Marine tanks require a specific amount of marine salt, which is called the "salt gravity," which must remain between 1.020 and 1.023 as measured by the hydrometer. Marine tanks also require a high Ph level (high Ph is more alkaline and low Ph is more acidic), and should be maintained in the 8.1 to 8.3 range. The crushed coral (like sand) acts as a buffering agent and helps maintain the required Ph balance in the tank. The temperature in the tank must be within the 72°F to 78°F range. The water is changed-out as follows: ¼ tank every two weeks, or ½ water change every four weeks. It is important to never, ever mix the marine salt in the tank, and to use sterile buckets to mix the salt and water before adding to the tank.
