Hi, Im alex, 19 years old. I just started my reef tank about 2 months ago. I am completely clueless to the whole reef tank business. I learned very little and so I started out with very little. I have a 20 gal long tank with a metal hallide light. Ive gone through 3 fish and now I'm on my last one. I started with a pink skunk, soon after a week I introduced a royal gramma. One day I came home and pink skunk jumped out. Then my sister felt bad so she bought me 2 oscellaris clown fish. Once I introduced them into the tank, I noticed the royal gramma would never come out to eat or anything, and 3 days later it dies. My clown fish died from ich I believe he was swimming really wierd and stayed at the bottom of the tank. It seemed as if his tail was getting eaten away at. Now i'm on my last fish. He has ich so I don't think I'll make it. I had the sudden urge to just give up, knowing that these fish were probably dying because on my ignorance. ZI have began just yesterday reading up on the internet on info on reef tanks. I didn't even have any test kits before yesterday. I bought them and the readings came out like this. Nitrite=0, pH=8.5, Phosphate= 0.25 or 0.5 (couldnt really tell), Ammonia= 0 or 0.1 (couldnt really tell), Nitrate=0 or 5 (again) What are normal readings on a tank that I should have. How regulalrly should I do tests and which tests whould I do regulary and how often? I have a hydrometer and it reads at 1.023 which is good correct me if i'm wrong. I was actually posting on reef central itself but I was told to start posting here so that people locally could actually help me out or get with me one day to talk to me more about it or even come to my house to check out my tank. Not to be rude in anyway but i feel somewhat iffy about it. Ive done an internet date once and it wasnt so bad she was amazing =) (lol) but meeting up with a stranger to talk about fish tanks or see my tank seems somewhat akward. It's not that I don't trust you people it's just.....O i guess you would understand, but maybe i'm wrong and it would be worth the experience. My last fish has ich and im not willing to give up on it what should I do to help him out?
