Has been an interesting 7 pages of reading. I just had a massive disaster today that sent me looking for answeres and I found this site.
Don't mean to hijack your thread, just felt like that it would be senseless to start another since yours answered so many good questions.
I have had a thriving tank ( well my daughters) for 4 years now. Only ever had 1 fish die and that was a green spotted puffer. We had a total of 10 fish including the two glo-fish we added yesterday. Well along with the two fish she wanted new gravel to match her favorite nfl team. So we evidently did a huge no-no.
Emptied the tank completely, washed everything down, including the filter. Filled it back up, added the water conditioner. Aclimated (sp) the new fish, put the old ones back in. Presto, this morning all the fish have died except the betta, and the algae eater. But even these 2 are no acting normal.
The water is now cloudy, but from what I read this is normal. I would assume it's just time before they meet mr. tidy bowl too.
Is there anything else I should do to get this thing back up and running?
God, my daughter is going to flip when she comes back this weekend
