A few years ago I bought an acrylic and it seems that if I even looked at it wrong, I would have a new scratch! It was a Clear for Life with a back section for bioballs which I ended up scrapping and using as an overflow for the sump. This time I want to go with glass but who makes a glass tank with the overflows? I have seen only one by All Glass and it looks like the overflows are built in the corners? Can't really get a good picture of how that works. Can anyone recommend a reef ready glass tank? I am looking for 75-100G with a preferred width of 20 to 22". The one thing I really hated about the Clear for Life tank was that by the time I added rock, there was just no depth left. Thanks
