im pretty sure i misunderstood your advice.... baking soda is okay, but requires a lot of supervision....1 teaspoon per 10 gallons. i SHOULD go with crushed coral, and put 1-2 tablespoons in mesh bag inside the filter i have that hangs on the back of the tank? i just did a 10 gallon water change, 5 minutes ago. Should they all be okay until the crushed coral comes? Also, the only reason i am doing a fish in cycle is bc I had started with a 32 gallon, waited until the fish store employee said my tank had cycled, and after 2 months, I brought home another fish to add to the community. My ammonia spiked, and i was told i was overstocked for that tank.. that is when i went and got the 65 gallon tank. I brought home another fish a little while later, and he got sick. Pet store employee advised i treat entire tank with Pimafix. The next morning 90% of my tank was dead. I had to immediately refill the 32 gallon tank with fresh water, and move the survivors into the smaller tank again. I washed all the gravel in hot water, and all the decorations in the dishwasher without soap.... I let that tank sit 2 days, and moved everyone BACK to the 65 gallon. The only survivors were 2 large angel fish, and 1 rosy tetra. I did go buy 2 guppies and 2 mollies to try to make the tetra feel more comfortable with being in such a large tank and being the smallest one in there. He had stayed hidden for about a week, and adding a few more smaller fish has definitely help him. Anyway, it has been a rocky road. Any idea how long it will take to cycle this tank?
