i bought a 50g custom tank with overflow a couple of years ago. i have no problem with the actual tank itself. i do have problems though. after having the sump set up, and then moving, the gasket for the bulkhead doesn't fit anymore and it has been a run-around trying to get a replacement part. also, being very new to sumps at that time, it was very difficult trying to find proper plumbing that would fit the bulkhead size.
now i am not using the overflow and sticking with hobs - emperor 400's. the plastic trim around the edges is not even. on the left rear half of the tank, it is a full 3/4 inch piece, i guess for the glass lid to rest on. it fits perfectly well along the sides though, and the extra plastic lip just makes the filter rest on it and sit up really high. the emperors are large and i worry about the plastic bending under the weight. on the right rear of the tank, the plastic lip is 3/4 inch on one half, and then, for reasons unknown, goes down to only 1/4 inch. there is a gap 2 inches wide all the way near the corner where there is no trim sticking out at all. this means the filter on that side is not properly supported by the trim and would sit sideways, except that i stuck a wine cork underneath the filter so it rests on top and sits level. very weird.
my other tank, recently purchased from them, is a big PITA and honestly, a waste of money. 150g, 60x24x25. first, the silicone job is very messy. they slap it on there and it's up to you to trim off the residue. oh, and clean it off from where they wrote all over it in black marker. make sure that the silicone actually connects glass pieces - they seem to have left silicone-free gaps on the egdes of some top pieces. they are heavy into reinforcing the tanks - extra glass around the bottom seams, and layers of glass on top to make the tops inset. of course, this makes the tanks extra heavy - around 350lbs. for this one.
the "front" of the tank has an unbroken upper trim with a solid piece of reinforcing glass that runs from side to side. i say "front" because you don't have a choice. the back has cut-outs in both the trim and the reinforcing glass. I assume this is for using hobs, which would rest directly on the back pane of glass. That is, if you can find hobs that fit. emperor 400's don't. penguin 350's don't. the walmart-marineland aqua-tech 50-60's don't fit. I'm really really glad that i bought 2 emperors specifically for this tank. what a waste.
I know that it's my responsibility as a customer to check the measurements and everything, but that thought had not even entered my head as i assumed an aquarium manufacturer would design tanks to accomodate common filter brands. i am running an XP3 which was supposed to be working with the emperors, not alone.
another thing - the problem with thsi design is that if something happens to the front of the tank, like a huge ugly scratch, you can't really turn it around and still have it look normal because of the missing trim and the exposed reinforcing glass.
i got a stand from them as well - either get a bookcase style if possible or plan on redoing the doors yourself. the doors have to be lifted in and out of position and come off completely. while this is okay in some circumstances where you want the extra elbow room that you don't get with a hinged door, it is very difficult for day-to-day access. i plan on taking the doors apart and putting in hinges so i can easily get to anything underneath - food, python, canister, power strip, etc.
the worst thing of all was spending $995 on 150g tank, lids, and stand, being unhappy with it as i mentioned, and then seeing a 220g Perfecto tank, lids, and stand for $1173.
. However, after reading Sandee's thread in the Setup & Filtration section, about the 220 gallon breaking 
, I've been a little worried. I was wondering if anyone has had any issues at all with the glass tanks from Glasscages. Does anyone have any stories, good or bad that they can share with me? If you bought one from them, do you still like it. Would you recommend them to others? Does anyone else have any places they order tanks from? Any help would be appreciated.
