Hi everyone, new the the group and new into salt water tanks and reefing. I have had freshwater tanks my whole life. I have had a 55 gallon standard tank that I will use. It has a frame with NO center brace on the top nor the bottom and the glass is 3/8" thick. I have used this tank since the 80's with no issues. My questions is: can I remove the top frame to use as a frameless tank (I will keep the bottom frame)? I have searched everywhere but all discussions are centered around tanks that originally had a center brace. Thanks in advance.
