had a 30 gallon tank while growing up but that's all behind me now. the tank that is - first a freshwater community tank in grade school, salt water in high school, oscars in college, then i gave it all away (including the 8" surviving oscar) to a friend's little brother. some years later now, am looking at a used 55 gallon tank (will meet it tomorrow). after starting the relearning process and perusing this forum, have discovered there's quite a lot that has changed or that i never knew. am sure to have many questions. would appreciate any general words of wisdom/best first tips. will at least let you know if i go for the tank. my biggest concern is filtration. it has an undergravel filter which i dont plan on using powered by two powerheads (Penguin 660s - 170 gph ea.) which am thinking i could/should use by themselves. and it comes with an AquaClear 70 hob. Is that sufficient? Am thinking i may also get another AquaClear 50. or have a line on a Fluval 305 cannister for a great price. well, will check back in later. wish me luck...
