How much space

[Azrt]

Just ordered a T8 to stack on my T 10. I will be using flexwatt for both cages. What is the best way to stack these so the top cage flexwat doesn't increase the ambient temp on the bottom? I may just get a heat panel but want to see the easiest solution so I don't have to spend more and wait for shipping, install etc

Any spacer between the tanks will do. Some people use hockey pucks, coasters, or other similar items.

Never thought about coasters. Appreciate the tip. Course the cage takes 5 weeks to deliver. Lol
