Q: What is the ideal temperature for a saltwater aquarium?
A: Some aquarists feel that keeping your tank between 75-77 degrees is best, some say 75-80 degrees. Others feel that some corals and fishes, having come from warm tropical waters, do much better at temperatures of about 80-85 degrees, or higher. Some invertebrates will even do better at cooler water temperature. Saltwater Tank Temperature Opinions
Q: How to use hydrometer for saltwater aquarium?
A: Rinse the hydrometer with clear water before filling it to make sure it is clean. Dip the hydrometer in your tank,and let it get filled completely. Take it out and place it on a level surface. Gently tap the side of the hydrometer with a pencil or plastic spoon to dislodge the bubbles.
Q: What is the best specific gravity for my saltwater aquarium?
A: – Rinse before using – Monitor your water temperature – Test on a level surface – Make sure no bubbles are trapped – Look at the hydrometer straight on
Q: Is brass harmful for salt water aquarium?
A: Salt contains sodium and chlorine, but it is nothing like either one. It is a new compound with its own unique properties. Brass does contain copper, copper kills corals and inverts. If this was in the beginning of the system it would be fine. But at the end of the system the water is stripped and looking to bind anything it can get.
