When you say ledges do you mean bracing? My first 4ft tank was braced and I struggled to get external installation kits over the bracing. Also braceless is more astheticly pleasing even with glass lids fitted. Have you thought about putting your cabinet on wheels like Mark Evans' tank?I can fit the length only if the cabinet is the exact same length. There is only access from the front so I'll reduce the cabinet height to help. All pipes will come from the rear of the tank.
Any pro/cons in having/not having ledges around the tank?
Were a friendly bunch and there are many very helpful members, but it would be best to place your questions within the various appropriate sub forums as this is really only an introduction thread 🙂Btw tnx for bearing with me through my ramblings!
