Bubble Magus and Neptune Systems have been two of the most reliable names in the aquarium industry for a long time. Attention to detail, exceptional reliability, and outstanding customer service are just a few of the characteristics that set these companies apart. Because of their reputations, you can be sure that your doser will be hobbyist friendly, have remarkable precision, and be backed by one of the best warranties in the market. Something that we have always been most impressed with by with both of these companies is their commitment to research and understanding the needs of today's reef keeper; how they are always trying to improve on already outstanding products. This is why we sell Bubble Magus Dosing Pumps and Neptune Systems Dosing Pumps at Reef2Land. Should you have any questions, please contact us.
