I guess I have been in my own lil world with my aquarium to long.I have been going through alot of threads here on the forums.Things have come a LONG way since I started mine.I always used to warn people that I hear are starting up a new tank,I tell them it takes years to get it self contained and maintain life in it.I see here,alot of people have had tanks a year or less,yes hold tons of life(I hope they keep going well)and do not seem to have any problems.I hope you can teach an old dog new tricks,as I have a ton of catching up to do.I have been thinking about setting up a 200-300 gallon tank the same way I have had mine setup,I just do not know if it works the same on a big tank,as my lil 75 gal....:oops:
