You are saying that your BG floats? Just trying to clarify.

The bg is naturally boyant and will float. Typically people will use silicone to adhere the bg to the glass of the tank. Then fill the tank and let the bg cure. Others are experimenting with the use of magnets to help secure the bg to the tank. You could try to remove some of the styrofome from the back of the bg and then fill the void with concrete. Doing that will reduce the boyancy, but I don't know if that would be enough to make it sink.

Bottom line is that foam/concrete bg's float. You have to use something to keep them under water.

using your bathtub seems risky... why not just buy a large rubbermaid type container?
