**Warning: This will be a long thread. I am in no hurry to do this. So keep the teasing comments to a minimum.... LOL jkjk ** You all did read right. I am in the thinking stages of an upgrade. I have decided after looking at some of the tank dimensions that I like the 180 gallon tank dimensions the best. I plan on pulling a Denzil and am planning on building the stand and canopy from scratch. So again, this will be a long process. Since I have just gotten the 90 up and going, I am in no big hurry yet. You guys will laugh when you hear my motivation: MOAR TANGS!!! (MOAR FISH!!) I will put up some plans as soon as Denzil teaches me how to use the software he used for his stand But for right now, I am thinking of doing a drain system like aqua-nut, since it was so quiet but also, possibly having two drains, and two skimmers? Not sure yet. Going to look into this a bit more, but I do know that I would like at least a 90 gallon sump. So if you guys have any advice or ideas, please feel free to post them here.
