A quarantine tank that shares the same sump or any water from the main display tank is not really a quarantine tank! A true quarantine tank should be a complete seperate system.
Live Sand is actually the combination of non-living substrate and a myriad of invertebrate and bacterial life in and on it, can be a tremendous contributor to optimized and stable water quality.
What works for you, works for YOU. Not everything that works amazing for you in your tank will work on someone else's tank or even in one of your other tanks.
The secret ingredient is always love. Food tastes better with love and Corals grow better with love. LOL
Most fish well become less colorful at night when sleeping as a way of hiding from predators, its ok if your fish looks pale in the mornings as they will be full colored during the day.
Some nearly blind pistol shrimp form symbiotic relationships with shrimp gobies. The gobies benefit from a protective burrow that they cannot dig on their own and the nearly blind shrimp has an excellent watchdog that warns of danger. Another interesting fact of these pairs in the aquarium is that the shrimp will often stroke the goby and the goby will defecate giving the shrimp a meal.
Clownfish from the pacific will sometimes host in anemones from the atlantic which does not have clownfish. My pair of ocellaris clowns took almost a year and a half before they finally started hosting in a Rose Bubble Tipped Anemone. RBTA are not usually listed as compatible with ocellaris clowns on most compatability charts.
If using common kitchen utensils as aquarium tools, it is important to use DEDICATED ones and keep them separated from those used in the kitchen, in order to prevent contamination.
Coral Used for Eye Implants
Spheres of precious metal, including gold, ceramics or glass have been used as implants to replace damaged eyes, but none has demonstrated the potential of coral for preventing biological rejection and ensuring a natural-looking eye.
Trust in your ways! Even though you may not be doing something by the book or the internet, as long as you carry it out thoughtfully it may work! If it doesn't it is okay, try again with modification. I use a hydrometer and have been using it for over a year now! Some people say they are inaccurate but if you make sure it is cleaned right away after use, it can be useful for a long time.
