The most rigid tape foam you can get is fine, you don't want an expanding foam or anything that compresses too easy. A better choice given the gaps being noticeable and what most people typically use is the 1/2" pink rigid foam from the insulation department but it's pink so not always the nicest thing to look at unless you cover the edges with tape or something. Ideally the stand should be better but 1/8" isn't terrible, rigid foam will compress with the tank and water weight enough in the right places to seal any gaps in support.
