View Full Version : Acrylic cross bracing

02/04/2015, 08:18 AM
Great Lake Aquarium offers acrylic cross bracing is an option on their tanks.

I am considering 96" long tank. I am going to use 2 Maxspect razor 300W 48" long each.

Will I have any shadows with standard black bracing?

Is the acrylic cross bracing mounted with nylon screws as strong as the one piece black ABS bracing?

It's hard to say if it is as strong, but if they are warrantying it and selling it as a viable option for their tanks, Im sure it is sufficient.

Since you are using two lights, if you have one center brace in the standard black you probably won't notice it, but if it concerns you, then peace of mind is a nice thing to have and you should go with the acrylic.

Is eurobracing and option? Or a thicker glass and rimless?

I believe rimless is not an option on 8' tank. I will be using 2 light sets. Each light set consist of 4 LED clusters. 12" between each cluster (aprox). There are 3 cross braces at the top of the tank. Black ABS is the standard.

Also, should I worry about heat?

Oh, didn't realize it was that large of a tank with that many braces. Maybe the clear braces are your best bet. Might still want to look at Euro Bracing.

There's a few different manufacturers that do this. As far as strength I would say it's equal to or stronger then the black brace. You have a thicker material with the acrylic. The black bracing does also give you shadows where the acrylic will not. The nylon screws are strong enough to hold. I have been running tanks like this for years, I just take my Dremel tool cut the bracing out drill holes add nylon screws and acrylic. Here's a picture of the bracing I did on my 100 gallon.
