At the moment I am using the stand. It is telescoping so I raised it much higher than before.
I think this weekend I will get the Rena XP4 for the tank. I still want to raise her basking area above the tank but I might just get some material to create a top so I can rest the basking light on.
Edit.
So my super cheap and paranoid way of covering the open tank is...an oven shelf.
Yes ladies and gents I pulled a shelf from my oven and stuck it on the tank.
Hopefully I can find something similar and larger this weekend but for now here it is

It isn't long enough so I slid it over to the side with the filter, which I am also going to change soon, so she wont climb on top of it and into my cats litter box.
