Sooooo as some of you know I've recently aquired a 125g that I plan on using for Discus.

I was looking through algae scrubbers when it hit me... shouldn't I just do a sump?? I have a free 10g that I could use for this.

Would that be doable? Would that size accomadate my tank? Would it be cheaper? Would it do the job of a canister filter?? And would it decrease the amount of equipment that I would have in the display?

I also have a 55g that I could use for this, I'm just very scared about the weight issue. I've already got 1000 pounds or so in my living room. Do I want to add to that??
