Temp is 76, ph is 6.6
I found what may be the cause, my nitrates are spiking, they are between 20 and 40 ppg. After seeing this, I did a partial water change and vacuumed the gravel.
I did not expect the tank to start cycling so fast! I had 2 fish left after my guppies were killed by my betta and then the betta died of some cancer like disease. I gave up on guppies and bettas altogether, I have had two bettas, and countless guppies, they just seem too tempramental.
I also switched to a power filter instead of my undergravel filter. I've been gradually adding fish... well not as gradually as I should... but hey, I was excited.
Started out with one cory which survived from the original setup, when the betta died I got another cory, then I added a sword tail a week or so later. After that is when I picked up the dwarf gourami. Two weeks after getting the gourami, my fiance picked up a clown plecto because the algae started growing like crazy (usually a sign of the nitrates.. I should have tested!). Then he wasn't cleaning too much so he picked up two small otocinclus(es?) a week or so after that. And the other day I picked up 3 diamond tetras. I guess I have had the gourami a little longer that a few weeks... it's hard to remeber.
The swordtail is the pig out of the bunch. Also, the otocinclus are pigging out on the algae. The tetras and the dwarf gourami are eating, but not much, and usually the second time I feed them in the day.
Will they start eating better after the nitrate spike is done? What should I do to make sure the nitrates don't kill the fish?
Thanks,
