INSTALLATION AND OPERATING INSTRUCTIONS

Aquarium Start-up Procedure:

A) Salt Water System

1. Install an undergravel filter.
2. Cover the undergravel filter with Dolomite or crushed oyster shells.
3. Add marine salt to fresh water per manufacturer's specification.
4. Install an electric heater and set for water temperature in the range of 73-78 degrees Fahrenheit.
5. Allow 24 hours for the salt to dissolve in solution.
6. Check water specific gravity with a hydrometer for 1.020-1.023. Adjust specific gravity of solution if not within the above range.
7. Install a power filter designed for a marine system.
8. Add gravel, or which 25% by weight comes from an established disease free tank. Freeze-dried bacteria mixtures may be substituted for the 25% disease free gravel.
9. Add a food source to promote Nitrogen-Cycle Bacteria.
10. When the aquarium is stabilized; i.e., the Nitrogen Cycle is balanced and Nitrite levels are stable for two weeks, then it is safe to add Marine Fish and Invertebrates.
11. Finally, now add the POLY-FILTER to the aquarium system.

B) Fresh Water System
Fresh water aquariums require no special start-up procedures. Any conventional procedure is acceptable for use with the POLY-FILTER, or simply place the POLY-FILTER in the water in a manner that prevents it from floating to the surface without blocking the flow of water over and around the POLY-FILTER.
