Review: Avoid some of the pitfalls of nonscientific saltwater tanks - 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.
Review: This is the best bacteria in a bottle you will ever find for ... - This is the best bacteria in a bottle you will ever find for the purposes of saltwater aquariums. It cycles your tank in a very brief period of time. Your tank will cycle in days, not weeks. You will not be disappointed to find that after dumping the entire contents of the bottle that the ammonia levels do not drop like with other brands. If you have an ammonia spike, this is the product to buy. DO NOT buy SeaChem Prime to safely lower your ammonia levels in your aquarium - especially if you already have livestock in the tank! That is the WRONG product! I forgot the chemistry behind SeaChem Prime, but DO NOT follow that HAZARDOUS aquarium trend - your ammonia levels will read 0 ppm on your test kits, but your animals will still show the same symptoms of ammonia toxicity and still end up dying. Use Dr. Tim's Aquatics One and Only Live Nitrifying Bacteria to SAFELY lower your ammonia levels in a freshly setup tank and an already stocked tank. Speaking solely about reef tanks, there is no such thing as overdosing this product. All corals have the ability to eat nitrifying bacteria to some degree or another. For me, there is no other brand of bacteria in a bottle - there is ONLY Dr. Tim's One and Only Nitrifying Bacteria! This stuff works, and it is safe for animals. And, no, I was not paid or bribed by anyone to write a stellar review for this product. I write good reviews for good products, and bad reviews for products that need to be struck down hard!
