Glass Aqua appears to be a legitimate business based on the information available. It is an online store that specializes in aquascaping and planted aquarium tanks. They offer products such as rimless tanks, aquatic plants, hardscape, planted aquarium CO2 equipment, and aquarium LED lighting. They also have a customer review system where customers can submit their reviews and photos for a chance to win a $100 Glass Aqua gift card. Furthermore, they have a presence on social media platforms like Facebook. However, it's always a good idea to do your own research and read reviews before making a purchase.
