benefits of one and only

Reef Safe One & Only Live Nitrifying Bacteria converts fish waste into a non-toxic form and removes ammonia and nitrite. By doing so, this instantly works to prevent New Tank Syndrome, which occurs when the water contains high level of ammonia and nitrite and there are not enough beneficial bacteria to process it, by establishing a biological filter in newly set-up fish tanks and aquariums.

Claims to start the tank cycle but this never occurred with our tank. Paired this purchase with their ammonia chloride to feed the bacteria.Readings never budged from 2ppm ammonia. 0 nitrite. 0 nitrate.We were doing a fishless cycle so expected it to take awhile, however the cycle never even began.Buyer beware if you're looking for a decently paced fishless cycle. Product doesn't do as it claims.

This stuff is absolutely amazing. I use it when I set up a new tank, or even sometimes after a water change just to beef up the beneficial bacteria. You can add fish immediately, no more waiting weeks for a tank to cycle. If you worried about over stocking, and about to add another fish, just add another bottle. My tank has never looked so clean and it totally skipped the "ugly stage" that most tanks go through. I always keep an extra bottle on hand just for incase moments. Once I needed to set up a hospital tank for a sick fish, and I didnt have time to wait for the tank to cycle, i just added this and then was good to go. Everyone who has a tank should keep this on hand at all times. It's amazing.

Saltwater aquarium set up is full of hoodoo vudoo. Some people may want to set up their aquarium over many weeks or months. I've heard it all toss a dead shrimp in the tank and wait for the magic to happen. Hum. That's not my idea of science. I hold a science degree with extensive work in biology and microbiology. My tank was set up with RODI water Carib live sand and rocks as well as dr Tim's nitrogen fixing bacteria. Water salinity and ph all within the appropriate ranges. Temperature was 78. degrees. I tested all aquarium parameters with the master test kit. I added 2 clowns a carpet anemone and some hermit crabs. After acclimation to tank temp and salinity these animals have done extremely well. The clowns and anemone have become acclimated all fish are eating and doing well and all critical tank tests show no dangerous levels of ammonia, nitrite or nitrate. Dr Tim has the correct nitrogen fixing microorganisms specifically for aquariums so does the sand and rock. I do have years of aquarium experience but this is my first saltwater tank. Dr Tim has experience setting up huge commercial aquariums and has a PHD in microbiology. You are free to choose hoodoo vudoo or science. I'll take science every time.
