Ammonia, Nitrites and pH

Testing the aquarium water daily is necessary to make sure ammonia and nitrite levels are zero and the pH is kept at the appropriate level. Also, keep an eye on the temperature of the water and salinity. Testing equipment and supplies include:

$60: Red Sea Marine Master Lab Test Kit
$60: Red Sea Reef Foundation Pro Test Kit
$10: Seachem Marine Buffer (pH buffer keeps the pH high enough with dissolved mineral content for the fish)
$130: Refractometer (measures the salinity of the water)
$25: Digital thermometer

Running Tally: $17,334
