I am at my wits end. I’ve kept small fish, usually betta, for quite some time now. Always had good luck. But over the last ~18 mos or so, I cannot keep anything alive. I killed goldfish, for pete’s sake. Who kills goldfish?? So I decided to try some guppy. I’ve now killed 7, in about 2 weeks time.
The only common denominator here is a water change! I am on city water. I use a tap water conditioner. I test my pH.
Most recently after the goldfish died, I completely emptied the tank. Refilled it with plain tap water (again, city water) but I did not treat it. I just left it to cycle and ignored it. After a couple weeks I decided to try again. I tested the pH of this plain water and it was at a perfect 7.0. I added some Stress-Zyme and got 3 guppies. For the first week they were fine. I did a partial water change and within 24 hours they were all dead. The water was treated with water conditioner prior to being put into the tank, but it didn’t sit for a week, so basically it came straight from the tap, into a bucket, into the tank.
I tested my pH again and now it’s at 6 or less, the (test tube) color is yellow. In the past when I’ve tried to adjust my pH up, using pH Up does nothing. The only thing that has worked is a pinch of baking soda. Apparently my tap water is going thru wild pH fluctuations??
WTH is going on??? What can I do??? I’m tired of killing my fish! And it’s getting expensive!
