ESV was our very first line of additives, from iodine to calcium. They were the first to come out with the 2-part Calcium/Alk Buffer system. We have seen many other products come and go on the market. Many of these products with big dollars on advertising, super nice fancy product labels, etc but ESV has endured just like us. We like to think for the same reason, they are a very good small business that cares about there customers. They make excellent products and maintain the highest standards. To this day, ESV is one of our most popular selling additives and we hope it continues to be for years to come. 

CPR was one of our first skimmer, wet/dry and overflow brands we picked up. Back in the 90's and early 2000's it really was rare to have a pre-drilled tank. So overflow boxes to create a sump under the tank was a must, or going with a hang-on-back skimmer. The CPR Bakpak was the #1 selling HOB for many years. It's still around today, although not as popular now so many people have access to Reef Ready tanks. It's still an easy to use and well built skimmer. Pretty much toss on the back and plug it in. We don't carry as much CPR items as we did years ago, but still feel honored to have CPR's on our shelf.
