I’ve used other brands to cycle a tank and this by far has cycled my tank the quickest. ### ⭐⭐⭐⭐⭐ Avoid some of the pitfalls of nonscientific saltwater tanks *by on Reviewed in the United States April 8, 2017* 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. ### ⭐⭐⭐⭐⭐ Seems to have done what it said it does. *by on Reviewed in the United States May 2, 2019* Cycled a 120g tank with Caribsea Hawaiian Sand, media balls (the ceramic ones) and dry man-made liverock.Used the ammonia by the same brand to get up to about 4ppm. By day 2 I had a massive nitrite spike and Ammonia was just trace. Added more ammonia day 3 to get to 2ppm. Added microbacter7 on day 3 as well. Nitrite spike did last about 5 days reading off the charts before it went to 0.Refugium was up and running when the Nitrites became readable (API test). I’m about 10 days in and am running at 0 ammonia, 0 nitrite, and about 10-20 nitrate.” With Chaeto growing nicely.I normally cycle tanks with gulf live rock and it takes about 4-5 days to get a stable tank setup. I’ve never really had the ups and downs of new tank syndrome. Will be interesting to see if I get the hair/bacteria/cyano blooms over the next few months. ## Frequently Bought Together - DrTim’s Aquatics Reef One & Only Nitrifying Formula – 4 oz – for Reef, Nano & Seahorse Aquariums – New Tank Setup & Water Quality Support – Pure H20 Cleaner - DrTim’s Aquatics Ammonium Chloride Solution for Fishless Cycling: 2 oz., Treats 100 gal. – Fish Tank Cleaner for Saltwater, Freshwater & Reef Aquariums - API SALTWATER MASTER TEST KIT 550-Test Saltwater Aquarium Water Test Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/6541547-drtims-aquatics-one-and-only-reef-drtims-aquatics-one-only](https://www.desertcart.gr/products/6541547-drtims-aquatics-one-and-only-reef-drtims-aquatics-one-only) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-06*
