The next step was to make the cage to hold the live plants and shelter any live minnows in the 40gal tank. It would also be the base for the ramp up to the common basking deck. Since the cage wall had to extend from one side of the tank to the other, it would have to be detatchable from the base in order to get the whole thing in there past the lip of the tank frame. I also wanted to be able to easily take it apart for removal and cleaning if necessary.
I started with an old plastic lid from one of those plastic storage tubs.
I was just the right size and also had a set of locking tabs that would I incorporated into the design nicely. I drilled several holes all along the lower sides of the cover to allow some good water flow through the gravel bed for the plant roots...
Next I superglued some tabs to the cage wall so it could be hooked to the front edge of the base...
Then I went to making the supports for the cage wall so it would remain upright and not get knocked over by the turtles. I cut out a piece of eggcrate that would eventually be glued to the cage wall and then extend back to hook under the locking tabs on the base. I measured the distance from the front edge of the base to the tabs on each side and then used a dremel tool to cut a groove into the eggcrate so the tab could lock into it...
I then superglued the first piece to one side of the cage wall...
Of course Nermel insisted on testing each piece to make sure it was strong enough to use around turtles.
Once it met with her approval I locked the cage wall into place on the base. You can see in the circled area on the left where the piece fits into the locking tab and the circled area on the right where the tab on the cage wall hooks over the edge of the base...
and here's the finished product...
Now I just had to let it sit and dry before i could put it in place, add the gravel and live plants, and make the ramp to go above it.
