cycling help

Hi The water was perfectly fine in my established 64L tank until I added more substrate. Covering the old substrate has, I think, caused the nitrite (as measured by an API test kit) to spike. Today it is 4.0. Ammonia is zero, PH is 8.5, nitrates are high (that's how it comes out of the tap)...

Hello! I got a 55 gallon tank over a month ago and I’ve been trying to cycle it using the fishless cycle with Dr. Tim’s ammonia and beneficial bacteria in a bottle. I’ve been following the instructions from Dr. Tim’s website but also referencing the forum here for more information. I’ve never...

Hello everyone! As the title suggests I would like some help/suggestions with setting up my newish tank. It is a 10 gallon half moon tank, rather than a typical rectangle tank. I will post a link to the exact tank and tank equipment at the bottom of the post, as well as a picture of the newly...

Hi, I am new to fish keeping and am taking it up because my 4 year old is fascinated by fish and wanted to get some for his birthday (which is next week). When I spoke to the person in the shop, they said a tank should be set up at least 24 hours before the fish go in but now I've read that...

Ok guys so my tank is up and running. I have included photos of my tests below. The tests have been completed after adding dechlorinator and biological starter. I am also using a filter that has been used previously by the person I purchased the tank from I just rinsed these under tap water. I’m...

So I have a baby female beta, 2 gold rings, a baby synodontis eupterus catfish, and a male guppy in an 8 gallon tank. I've had them for exactly just over a week now. However, I didn't have time to cycle the tank for 2 weeks before I added the fish, as they were a gift. I've been using 2 drops of...

After a little help here, as I'm non-plussed. I'm mid-fishless cycle with a 450l (120 us gallon) tank and my nitrite readings are making no sense to me. I started with adding Dr Tim's ammonia a couple of weeks ago, plus "one and only" bacteria. I know there are mixed views on whether it does...

I can dig through my posts to find the exact date I added it, but I dosed my 10 gallon betta tank with tetra safestart plus with the addition of smaller doses of regular safestart directly to the filter. I am doing a fish in cycle and I'm testing using test strips. My ammonia is between 0 and...

I'm doing a fish-in cycle assisted by tetra safestart and my betta Hank. Unfortunately I don't have the API test kit like I want, but I do have strips (which I've been told a lot that are unreliable). My ammonia levels are between 0 and .25, which is lower than before I added the ammonia, but my...
