hi guys, I am a new aquarium hobbyist, came into this hobby quite reluctantly but ended up loving it.
I just upgraded my 5 gallon tank to the Fluval Edge 12 gallon tank about 3 weeks ago. However, I've found that my fluval edge tank is cycling in a strange pattern....
Here is the water parameter tested today with API kit:
PH: around 7.6-7.8, this one never come out exactly like the color on the chart
Currently the tank has 3 guppies, 1 guppy fry (1 week old), 2 platy, 1 sword tail, 2 otos.
The tank is planted with 4 javafern, 1 small anubias barteri, 1 huge anubias nana each attached to a piece of driftwood (still leeching tannin, but the carbon is keeping it down)
I got impatient and moved my fishes from the old 5.5 gallon tank to the new one after only 2 week fishless cycling, I was worried the old tank is getting too crowded for 8 fishes. I was lucky that I didn't lose any fish in the transition. I used to test my old tank and there are always 5-10 ppm nitrate in there. However, I've tested my new tank with the 8 fishes and 1 fry in there many time and there is still no sign of nitrate. There was a slight ammonia spike on the first day of transition, today is the 6 days, the ammonia is gone, no sign of nitrite or even nitrate. I'm getting worried that without nitrate my plants will die (I'm a bit of a tree hugger)
. Used to have an amazon sword plant but it didn't last in this tank due to the low amount of nutrient. I know Java fern and anubias don't require much but I'm still quite worried.
My question is: Is it normal for a seemingly established tank to have no nitrate?
