**CUSTOMER NOTICE** Due to unforeseen circumstances caused by ill health, with much sadness we have decided to close Reef Lounge Aquatics. We would like to thank all our loyal customers, suppliers, family and friends who have been instrumental in growing the business and supporting us through our journey over the past 2 years. This was a very difficult decision for us to make and we would like to invite you all to a closing down sale which will begin this coming weekend. We look forward to seeing you all in the next few weeks. Best wishes The Reef Lounge team.
