Specially formulated foods and substrates make tropical fish tank upkeep a breeze. Your aquarium plants, cichlids and loaches will benefit from our high-quality line of fertilizers, additives and supplements. Fish tank supplies can differ significantly for marine and reef aquarium hobbyists so we stock a ton of saltwater specialty products like calcium reactors, protein skimmers and lighting to grow delicate coral and invertebrate. Stable water chemistry is paramount to the health of saltwater aquarium inhabitants and even more so in a reef tank. Regularly testing key water parameters like pH, calcium and alkalinity will give you the knowledge you need to properly maintain their levels. The right balance can be achieved through manual and/or automated dosing of key minerals found in seawater. Additives, supplements, salt mixes and filter media can each affect the molecular makeup of your tank water so it's important to know what you're doing. Choosing the right fish supplies may seem daunting. Do not hesitate to contact us if you have questions. We are happy to share our aquarium expertise with you!
