Hey guys, so this is my story:
I started with a 2.5 gallon for two goldfish and soon found out they needed bigger. I got a 35 gallon acrylic that used to be a saltwater tank. It had been dry for many years. I cleaned it with hot water. I added pea pebbles purchased from walmart, a few fake aquarium plants and a fake aquarium castle. I added cycle for 2 weeks like directed but did not have a water test kit to test anything yet. I added my goldfish and a pleco, along with a rescue ID Shark and two mollies.
2 Days later my pleco died. He showed no signs of disease. There was then an Ich break out and my goldfish started acting funny. I moved the mollies back to the 2.5 gallon which I still had running. They were becoming agressive towards the goldfish.
The goldfish then became sick. It appeared in this order : Ich, Constipation, fin rot, scales falling off, and then death. I was treating for ich with quick cure as directed. I also started treating the fin rot with melafix as directed. Once the goldfishes scales started falling off, they died within a day. They died 3 days apart. One of them went from heathy weight to aneraxic looking over night. My ID Shark died 4 days after the goldfish.
Now here is my question. Since I really dont know what killed them all what do I do with my tank? I hate the thought of emptying it out and refilling it. Could I just overdose the water with a parasite killer or somthing to kill everything and then restart the cycling process?
I was in the process of a cycle. It had been set up for 5 weeks total (2 weeks without fish) and just had a nitrate spike as the fish were getting sick. My ph is 8 ammonia is 0 gh
is 8 kh
Any advice would be great
