Okay, so I have been here for a while, and my tank's life and lifestyle are rapidly decreasing due to an error of ignorance on both mine and my fathers side. I am preparing for the worst, as my population of 17 has gone down to 11. I believe a combination of stress from the ich and a bit of an overdose are the key factors in my decreasing biological ecosystem. So, I am preparing for them to die. While I hope they won't, I am planning that, in the event of the final death, to start cleaning my tank extremely, and waiting for four weeks. After this I plan on adding some additional tablets to help in the process of cycling. After this I plan on waiting for about 6 weeks and ten going to buy one figure 8 puffer for my tank, to start over. I also realize that the water should be relatively hard, the pH level being at a steady level of 8. Could anyone help me, I am currently reading up on their care, so I do realize certain things about their care, but I need some help about exactly how to set up my aquarium for them...
