My plan is to DO IT RIGHT THE FIRST TIME. THat is why I asked the question. I know that many things in the aquarium hobby are...or should I say "were"... all trial and error. But thanks to the web and forums such as this one, it is much easier to learn from other keepers experience (aka mistakes
).
Today a buddy called me offering a FREE 90 g tank (w00t)...so my newly set up 55 reef tank may get recycled to be a sump...with a good size fuge!!!
