I have four tanks, and I'm working on getting them all cycled. Most of them are progressing along fine, but one is giving me issues.
It's a 3 gallon tank, with one male betta and two ghost shrimp in it, all of whom appear happy and healthy. It's got black gravel substrate and a number of plants, most of which appear to actually be doing pretty well.
Over the last week, due to some other obligations, I've only been able to check my tanks' ammonia levels ever other day. My two five gallons have said nothing to very low. My other three gallon has said very low. This one (Jayne's tank) has said 2.0 every time. I'm using an API ammonia test - the kind with the two types of drops, and it's turning SCARY GREEN every time I test.
So I've been doing a 50% water change every two days. But this has been happening for a whole week. So I'm curious. Why would it be so much higher than every other tank? Why would it get so high so quickly? Is something wrong?
It's got a tetra whisper filter with an aquarium sponge baffle in it, a heater, and a piece of aquarium decor along with all the live components listed above.
I've got an API kit that tests for 4 parameters with the little test tubes on the way, but right now, I've got some strips for water testing the other parameters, and everything else is fine. Nitrate and nitrite are showing at 0, and while my water is a little high in pH, everything is great.
I'm using the same tap water in every tank, and I've been cutting back on the amount I feed, and I try to feed all four of mine the same amount as well.
