Thanks! It's my first tank ever, and it's only been going since March. But, so far so good! I have bought myself a new heater and a new filter since then (little did I know how junky the "starter kit" heaters/filters are. (All-glass) But for my 10 g, I have a filter rated for up to 30 gal and a 75 Watt Visitherm stealth heater. I have also changed my lighting to CF bulbs and my sand substrate for my corys! They loooove it.
