Hello I’ve been cycling my 40 gallon tank for more than 2 weeks. My ammonia has been around 0.25 for the past few days while my nitrite has been 0. My nitrates is 2.5 and it’s slowly going up 0.1-0.3 everyday. Is my tank ready for fish and should I do a water change?

Hello, I’m starting a new 40 gallon tank and I’m wondering if I can use live rock as a source of ammonia so I can add Dr Tim’s one and only nitrifying bacteria. If I can should I add the bacteria immediately?

Disclaimer: This is my first Saltwater Aquarium, I’ve only had freshwater before this. I recently picked up a 32g biocube from Facebook marketplace. I used treated tested tap (very clean water supply, reviewed water quality reports, de-chlorinated. I WILL BE USING RO/DI FROM NOW ON) I added...

Hello guys ! I’m very afraid because everything was good in my aquarium. Perfect parameters. But since Tuesday nitrites appear, starts with 0.1 ppm, then 0.25 and today 0.5 ppm !!! Im very afraid! My parameters: Amonia: 0 P.H: 8 Alk: 9.6 dKh NO2: 0.5 PPM!!! NO3: 0.1 PPM PO4: 0.11 PPM SAL...

Hey everyone, I'm seeking some insights and guidance on my reef cycling process. I initiated the cycling process on March 18th, which means I’ve been cycling for approximately 47 days now. Once the ammonia level dropped to zero on April 3rd, I began testing for nitrite. Currently, there are...

Hey all! Been cycling my tank and it’s been all good up until the last 2 days. Nitrites are at 3ppm and nitrates are at 40. Nitrites had been consistently falling from 10ppm until yesterday. My tank processes ammonia in about 24 hours when I dose it up to test which I did for the first time...

I’m about 2 weeks in to my cycle that started by dosing 1ppm ammonium chloride and used Dr tim’s one and only bacteria. when ammonia dropped to 0.25 each time i redosed ammonia waiting until it got broken down fully in 24 hours. My nitrite started to rise on day 2 and continued to (my salifert...

I recently bought an imaginarium test kit. And every time I test for nitrites I get a purple coloration instead of the blue colorations that this test kit says I should be getting. It could be an accident on the part of the packaging that includes the legend. But I'm not sure. for reference...

Hello everyone, Five days ago I started my fishless cycle using Dr Tim's one and only, my water volume is 14.5 gallons and I dosed the whole 4oz bottle. The reading for each day are the same each day Ph 8.0, Ammonia 1.0 and Nitrite 0. I tested my Nitrates today and it's at 5. Is my tank...

Quick question guys. My ammonia, nitrite, was zero, nitrates were in the usual range, ph a little low. Did WC, added ph buffer to bring ph to 8.2 , ammonia 0, nitrite 0. Added 4 new fish. The ammonia increased to .25, fish were doing fine, I was adding fritz turbo 900. The nitrite was still 0...

So I need to clean my filter, not necessarily replace media just carbon. Last time I changed the carbon I noticed a lot of gunk in there. I have a fluval 307 canister and I’m deathly afraid of cleaning it because of wiping out the bacteria and I don’t want to have a nitrite or ammonia spike...

Hey guys, I’m currently doing fish-in cycling of 2 tanks (not by choice). I came home and my mom decided to completely clean my 65 gallon tank and set up my new 125 gallon tank. So when I came back home, the tanks were clean and she separated my angel fish in between the 2 tanks. I quickly...

Hanna Instruments 7 in 1 Marine Checker/Photometer ^ ^ II II II II Has anyone had any experience with one of these? I know they are new to the market; I don't even know if they are released yet...

This question has two parts: 1. My first tank (40 gallon) has been running for about a week and a half. I've seen lots of change in my nitrite levels culminating in a spike last night, however my ammonia and nitrate have been borderline undetectable the entire time. Is this normal? 2. I...

I’m beyond confused. I’ve been in this hobby for almost 20 years and this has never happened to me. I sat up a 32g AIO, 2 months ago. RODI water, plenty of rock, and used Fritz Turbo Start (like I have many times before) and introduced a couple gobies to the tank. It’s been over 2 months now...

Brand new to the hobby here. This is my first attempt at a nitrogen cycle. I used the Dr. Tim's method and followed the instructions exactly. I'm getting a bit concerned because nitrite processing seem to be stalled. Here's my setup and parameters so far: 75 gal tank + 20 gal sump live sand...

In the beginning of my issues i was struggling with high alk and high phosphates. Its been around a week and i have been doing daily 5-10% water changes to lower these with rodi water. I know nothing good in this hobby happens fast so ive been expecting this to take a few weeks to resolve but...

I started a 36 gallon saltwater aquarium on a sunsun 304b canister not using the uv light, with seachem matrix as biomedia, with dry rock, 2 anemone, 4 clowns, 10 crabs, and 1 lawnmower blenny. One anemone found a way to get sucked into the filter. I cleaned the filters with my well water...

I have a ~400 gallon tank that was previously running that’s being started up again, but I’m running into a strange problem. It cycles out ammonia usually in 24-48 hours, but nitrite is taking 2-3 days. Parameters: Ammonia: .5 on API and 0 on salifert Nitrite: .5 Nitrate: 25 PH: 8 SG: 1.026...

I’ve recently brought a saltwater tank and after cycling it added 3 fish. After a week of having the fish in the tank I’ve had a nitrite spike, due to my own fault of feeding them too much the first few days whilst getting used to it all. A visit to my LFS (10 days into spike with nitrite...

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 fellow reefers! I just past the 2 week mark of cycling my tank using dr tims one and only and dr tims ammonia. I used live sand and some rock from my existing tank as well. My current parameters are Nitrate 20, Nitrite 0.5, Ammonia 0. I got the same results from API and Red Sea test kits...

Just did my weekly tests…my ammonia is 0 yet nitrite is showing as 4! And nitrate is at 8.6. I tested the salt water and both are 0 for nitrite and nitrates. I also tested my ro water and both are 0 for nitrite and nitrates. about a week ago I added some fish and my ammonia went up to 0.10...
