Hi
You can use this custom css to move it to the left:
#back-to-top {
right: auto !important;
left: 30px;
}
To remove it, just edit this file: /templates/ja_morgan/tpls/blocks/footer.php
and remove this snippet of code:
<!-- BACK TOP TOP BUTTON -->
<div id="back-to-top" data-spy="affix" data-offset-top="200" class="back-to-top hidden-xs hidden-sm affix-top">
<button class="btn btn-primary" title="Back to Top"><span class="ion-ios-arrow-round-up"></span></button>
</div>
