Newbie here. Had fish tanks when I was younger, and don't think I ever lost a fish. Now, I have a 10 gal
aquarium for my youngest son and we can't seem to keep guppies alive.
The setup is two weeks old. After letting the tank normalize over a four day period, We started with two guppies and a Corey. Both guppies died after two or three days and we replaced them. One of those guppies died, and we replaced it with a gold twin barb. Then the other guppie died and we replaced it with a cherry barb. Now the cherry barb does not look good. The Corey seems fine.
My ammonia levels are high (4.0-8.0 ppm
) and my Nitrite levels are zero. Makes me think the biological filter isn't kicking in. I have been doing 25% water changes every three or four days. After the change, my ammonia readings are around 0.5 -1.0 ppm
. After two or three days, it is back to 4.0 ppm
. I have been using an ammonia detoxifier in the meantime, while waiting for the biofilter to kick in. Also, tested my PH for the first time tonight only to discover that it is 6.0 or lower (test is only good down to 6.0). Tank temp is around 74 deg.
I hate to introduce myself and jump right in to asking for help, but I am at the end of what I know about aquariums. Any input would be greatly appreciated.
