I am getting back into the hobby after not having a tank for 10 years. My husband finally let me get a 10 gallon tank. I have it all set up and running and treated it with a water conditioner to get rid of chlorine. The temperature is about 76-78 degrees. Is there anything else I need to treat my water with? I plan on getting the API master test kit (after I convince the hubby) before I put fish in. I have a couple of questions: 1. I am torn between platies and guppies. 4-5 of one of those and all male. Which would you choose? Also thinking about putting some shrimp in there. How many? 2. How often should I change water (and how much) after the cycle is established? 3. Can I do a fish-in cycle with 2 fish? How would you go about doing this? I have read about the nitrogen cycle, but need to multiple times more. Would you suggest using tetra safestart? 4. What are the "have to have" items to maintain this tank? I really want to do a good job at keeping this tank up. Last time I had a tank I was a teenager and failed at doing the water changes. I also have a 50 gallon tank coming (my parents got it at an auction for me for $5). I want to get this tank eatablished and going well before I even attempt the 50 gallon. Thanks for all of your help! I am excited to get this tank started!
