The AquaticLife 115 I have in my Nano is only rated at 30 gals, so I would say not- but the Hydor my LFS suggested was $200. so I thought I would wait. Then I checked the dimensions of the Hydor and it's 4" x 4.5" so won't fit in the back chamber unless I cut the top plastic lip, and would rather not do that.

So I'll need to research other options, but I'll try the 115 first. My biggest problem with it on the nano is that it doesn't work well unless the water level stays constant, which doesn't in the Nano back chamber. Another thing I love about the new tank is that the right 2 back chamber levels stay constant so evaporation does not effect it.

If you know of any better skimmers that would fit in the space (4"D x 5"W, but the top opening is only 3.5"D), please let me know! Thanks!

Thanks! I bought it from my Pasadena Topical Fish here in Calif. They had a 50 gal model I liked except it was only 15" deep so the front display area was only 10.5" deep- too shallow for rock and a nice sand area (and space behind he rocks). But I liked the design of the tank so much I went searching online.

On the manufacturers website http://www.advanceaquatanks.com/uniq.html I found that they offered a 55 that was 18" deep. 3 extra inches worked perfect for me. I only found a couple of sites that offered that size for sale (they have another 55 gal but it's 15" deep & 24" high- too high for lighting IMO).

This is the cheapest I found: $635. & free shipping: http://www.acrylicaquariumsdirect.co...m36x18x20.aspx PetSmart was $729. There are alot of other sizes & shapes so another may appeal to you.

BUT even $635. was out of my price rage, as I wanted to keep the total cost under $1000. and was determined to get LED lighting! I noticed my LFS was selling the 50 gal. for only $359. when it sells online for around $565. So I asked him if he could get that size and how much would it be? He got back to me with the price of $400.! I couldn't say order it fast enough! 3 days later it was in the store. I thanked him for the great price and he said it was because I am a good customer! So awesome! Thanks Steve! And I love the tank!

I do see used ones for sale on Craigslist sometimes- not sure if they are the uniquariums with back chambers though. (and you thought that was a simple enough question, ha ha)
