Hello! I am new to this forum, I am so glad I found you all!
My 9 year old daughter got a new 10 gallon fish tank for her birthday. We set it up (gravel, filter, heater, plastic plants/decor) about 3-4 weeks in advance. I tested the water weekly with our general hardness GH
has been around 60 ppm
, that hasn't changed, our Carbonate hardness KH
has been around 40-80ppm, our ph has been around 7.5. Our Nitrate has been 0ppm and our Nitrite has been at 0-.5ppm.
Yesterday, we bought 6 glo tetras and brought them home. We let the bag sit in the water for about 30-45 min then added the fish. About 5-6 hours later, one fish died. Then overnight, 3 more fish died. We now only have 2 left. I tested the water again this morning and everything seems stable except the Nitrite is now around .5-1ppm (approx...hard to tell with the simple test strips). The Nitrates still appear to be 0ppm.
Can anyone help with why they are dying? My 9 year old is heartbroken.
Trying to save the last 2 and hoping to go purchase 4 more to replace. Just don't want to keep going through this process. If anyone can help, please reply. And if you can use layman terms, that will help me, I am a newbie to these conversations. I read posts about this issue and I don't always follow the terminology.
Thanks to anyone who can help, I didn't know fish ownership would be so hard.
