My husband and I have a 40 gal
Marineland tank. We have a large air stone, a bubbling drawbridge as well as a plain air hose just to create some bubbles at the surface. All in all, should be more than enough oxygen for the fish.
Our levels had been PERFECT for the last 3 weeks. 0 ammonia, 0 nitrite and 0 nitrates. Our pH fluxuates between 6.4 and 7.2. Most of the time, it is right around 6.8.
Our temperature is regulated, and is sent at 73. Oh, and we are running 2 marineland penguin 200 filters with biowheels (so i dont think filtration, or bioload is our issue) We use 2 filters in each so we have pleanty of room for our bacteria to colonize and we only cleaned 1 out of the 4 this weekend.
We have one black moor, one goldfish, one pleco, one small white goldfish (idk my husband bought him) and 2 tiny koi looking things. (They are maybe 2 inches at max)
These fish have ALL been in the tank since day 1, the tank was fully cycled and our levels stable. This past weekend, during a run of the mill water change and gravel vac, we finished up, added our cap full of prime and went off to finish cleaning the human habitat. When we went back to check on the tank 3-4 hours later, it was cloudy. We assumed at that point it was just because of the gravel vac and water change, so we left it alone.
We woke up the next morning, and the water looked like milk. Our ammonia level creeped from 0 to 1.0ppm, our nitrites were .50 ppm
, nitrates were still 0.
We added some ammolock, and some aquarium salt which i had hoped would bring them back down to 0. That did not work. I thought (originally) that maybe this was some kind of bio bloom and it would clear up in 3 days. We are going on a week later, and my levels are still jumping all over the place.
Our pH has been hovering around 6.4. Our nitirtes are between .25 and .50 ppm
, and the nitrates are 5ppm. Our ammonia is off the charts (reading over 8). We have been adding the ammolock. We have the Seachem AmmoAlert in our tank, which clearly shows the level is currently "safe" at less than .25ppm. With that all being said, we have read that there are false positives on API Master Test Kit results when you use Prime products. I was curious, so I tested a tap water sample with Prime, and even just straight Prime and neither peaked on the ammonia on the API master test kit.
So, at this point I am totally lost, very confused, and my daily trips to the fish store are getting me nowhere.
My fish all seem to be doing great, except my black moor. The moor seems to be swimming up to the surface more often because I think she is hungry. She is an "affectionate" fish and gives little kisses and rubs on you when you are cleaning the thank so I think she surfaces every time I walk into the room because she thinks theres food involved.. I have only been feeding them every other day, thinking that maybe I was feeding them too much?
