oh me...oh my... well, it's been about 6 weeks now since i set up my tank. about one month since i added three zebra danios. absolutely nothing has changed with any of the values yet. to this day, they remain: ammonia 0.25 nitrites 0 nitrates 5-10 lol! i'm not quite understanding the process...the ammonia has never spiked...despite fish pooping left, right and center in there. the fish are as active as can be. eager eaters, swim constantly, their colours are bright, vivid, all three have grown significantly, i'm noticing quite an increase in size, they are robust little swimmers, they all get along with one another, no signs of physical stress. they are so wonderful to watch. the water is clear. bear in mind that i'm adding a large dose of prime every second day. about two cap fulls. i can't remember where i got that idea from...lol...i think i read something about overdosing the tank during times when ammonia is present. could it be that three danios aren't enough to create a hearty amount of ammonia...? the prime doesn't actually mask the ammonia from being detected by my test kit...does it? my tetra safestart is STILL not here. waiting patiently! i changed about 20 percent of the water yesterday to get rid of some excess food. i'm starting to get the hang of how much to feed without overfeeding. i've also gotten a pretty kick butt handle on gravel vacuuming, lol. the entire water change process yesterday took me a grand total of 10 minutes. today is pay day so i'm thinking of picking up a couple of trees, and perhaps one of those colour changing bubble wands. my kids would love that.
