Almost every aquarium keeper tests water and needs refill packs for their water tests regularly. At JBL's, they can obtain refill reagents for each test, thereby sparing their purse and the environment. That is because the glass cuvette, colour chart and syringe for precise filling contained in the original test can be used over and over again.
The specialty stores are provided with shelf stands free of charge to exhibit JBL's refill packs that aren't suited for hanging on a hole board.
JBL is glad to be able to supply another component for environmentally aware aquarium keepers and pond owners with these products. After all, aquarium keepers are usually very interested in saving our planet!
