cycle aquarium

I'm going to be upgrading from a 2 year old 90 gallon system to a new 170 gallon system that will be going in the exact same spot. I'm planning on transfering all livestock & rock immediately to the new tank (I'm completely replacing the sand with new). Is this safe or do I need to figure out a...

Hi all! So I have my new brand new 32g tank stocked with about 25 lbs of rock donated by a friend with an established tank. It's full of critters, bristle worms, things slightly smaller than ants that crawl around all the openings, and even a few ball anemones, etc. The tank has been running...

I’m building my first tank and I have everything set up and ready to go. I plan on cycling the tank with live Carib Sea Agra Alive, Dry Rock, Fritz Turbo Start, and 2 Clown fish. Will it be okay to have the Agra Alive sand and Saltwater running in the tank for a couple days before I add the...

I’m currently on my third going to fourth week of cycling and my ammonia reads .25 and nitrites is a deep purple kinda hard to tell which one it is and my nitrates is about 10-20 ppm and it’s been stuck like this for about a week. I did a 25% wc then a 50% 2 days after and it’s still reading the...

Hello! I’m new to the hobby. I’m in the process of cycling a 29 gallon tank. Have live rock, dry rock, live sand. And by recommendation used Fritz Turbostart 900. But I’m confused. added ammonia to get things going. I’ve been testing the last five days. As of today ammonia is present and between...

As the title says, I upgraded to an Innovative Marine 25g lagoon FROM a Fluval 13.5. I've had the new tank running with no lights and the old ceramic media in the back for about 3 days now. I'm planning on putting the live rock in today and testing the parameters. I guess my main question is...

Looking for advice on lowering ammonia in my 30 Gal tank with one Clownfish. Two months ago I tried a fishless cycle with live rock. All my levels were low, ammonia was at zero and nitrate levels were there, but not high. I thought it was cycled and added the clownfish. A month later ammonia...

So I'm building my second tank and looking for other ways of cycling it (I cycled the previous one the "traditional" way by introducing some bacteria through a used filter and ghost feeding, no issues encountered). I've been polling other threads in FB and everyone suggest "time" and patience...

I recently set up a 15-gallon bare bottom tank using media and rocks with coral from my established tank. I have a single lightning clownfish and I decided to bring over the anemone from the old tank to the new tank. The coral is doing great, and so was the anemone at first. For the past few...

I apologize for all the cycling posts lately, just want to be sure I get all of this right! ICYMI: 55 Gallon cycling for 2 and a half weeks having used Dr Tim's Ammonia Chloride to bring ammonia to 2.0ppm once and added Brightwell MicroBacter XLM 15x Nitrifying Bacteria. 42lbs arragonite, 20lbs...

Hello everyone! I’m currently going on my 3rd week of cycling my tank I just wanted to reach out and see if these are normal parameters for going on the 3rd week of cycling! Thanks for the help! Ammonia 4.0 ppm Nitrites 0.25 ppm

Hello everyone! if I used some ceramic o ring and 100% established water from DT , will it instant cycle my quarantine tank??

First post here on R2R! … I am new to the hobby but have been reading/studying it for years. I finally have space at home to begin. I will be following up in the future with build threads for my salt water mixing station, QT tanks (invert and fish), and display tank that I’m still building...

So I was talking to another reefer the other day and we got into the topic of cycling methods. When I got into saltwater, my LFS introduced me to a very effective and quick method that is seemingly uncommon. He would add a cap full of pure bottled ammonia from Walmart per 20G and add in a piece...

How do you guys feel about Dr Tim’s Fishless Cycling System? I’ve researched it a little and am considering buying it when I’m ready to start my tank. It comes with bacteria, ammonia, and instructions. For a noob like me that seems like a home run. What do you guys think?

Just getting back into the hobby after 25+ years… yeah, been some time from the days with the only cycling technique being the obligatory, sacrificial Blue Chromis. So, we are planning mixed reef and starting with the display tank (+/- 80 Gal custom) and a quarantine/hospital setup (possibly...

Hi! My tank just finished cycling and is ready for live stock. Should I turn on the lights and start adding a CUC? Wait and see if algae start to bloom to determine CUC? I am not sure of the direction to go here. Thanks!

Hi Guys, i started cycling my new aquarium 40 days ago. I first used dr tims one and only but it seems that bottle was dead as i saw no reduction in ammonia 17 days. Went to my LFS and they suggested adding the Red Sea reef Mature kit as they believe the bottle of dr times could have been dead...

Hi All, Vitals Below: Ph - 8.0 Ammonia - 0.1 Nitrite - 0.0 Nitrate - 2 KH - 7.0 Phosphate - 0 Calcium - 324 Mag - 1318 Since having the tests run (day 7) through a LFS machine and then testing with RedSea Reef Test Kit at home I haven’t had any movement in Ammonia, or the others… So...

Hello I need a little bit of help.. my tank is in the process of cycling and it’s actually almost done but I want to change the salt before I add my clowns. I started with dead dry rock. I am currently using the tropic Marin pro reef salt but I won’t be having corals for a while because I rather...

Hey all, I’m about to cycle my new tank for the first time using Dr Tims Aquarium Systems - Start Your Tank. Reading the instructions it says to add fish/coral on day 2… I’m sure the store will have what we’re after in time. I’d like to get a jump on the cycle. Ideally we can start...

Hi First time here setting up a 75 gal mixed-reef. I am getting ready to set up and cycle the aquarium and want to know if I can use a wet sand (Caribsea AragAlive) sand with my initial cycle plan using dry-rock and a Microbacter Dry Rock Bacteria Starter Kit - Brightwell Aquatics. Will this...
