Still, if the substrate is no longer a benefit to the tank, it must be swapped for something new. Selecting a New Substrate Sand substrate is known to cause nutrient levels to rise over time, making it necessary to replace sand every 2-5 years. Sand substrates collect detritus, which is why most saltwater tank enthusiasts regularly vacuum their […]

The Types of Fish that Glow Under Ultraviolet Lights

Black lights should not be used to heat a fish tank or provide light to fish. Fish need aquarium lighting that’s designed to provide the natural lighting they would receive in the wild. Because black lights are ultraviolet, it’s only safe to use them in small doses. A black light in the 315 – 380 nm range is the least harmful. Use the black light in small doses, such as an hour or so a day, to light up clownfish, neon tetras and other fishes with fluorescent, white or silver coloring. Clownfish Clownfish come in a variety of colors, including: […]

Balancing pH Levels in Freshwater and Saltwater Aquariums

Using a scale of 0 – 14, pH strips test the chemical levels in water. In general, a score of 7 is considered neutral and most fish thrive in a pH of 6.4 – 7.8. Finding the right balance of chemicals is essential because low pH is highly acidic and can burn fish, while higher pH balances feature high doses of alkaline which chaps the skin. The best way to ensure a long life for your fish is to consistently maintain pH balances, not allowing them to significantly change at any point. pH Levels in Freshwater Aquariums In general, freshwater […]
