For Our Local Customers - Beginner Classes: Do you need to learn about filtration equipment, cycling, and water quality? Come in and talk to us. Say "NO" to biowheels, canister filters, and tanks without built-in overflow! In this section, we break down recommended filter systems for different size aquariums. We suggest actual products that we use to build custom aquariums around Los Angeles. We also explain the different plumbing parts. Please note that all systems have variables and there are endless possibilities of how systems are built. But these are samples based on our experience. Philosophy / Concept Our concept of filtration is that it should mimic the natural reef ecosystem as closely as possible, and should include a UV sterilizer to control disease. As water passes through masses of live rock and sand in the coral reef, bacteria living within the rock and sand break down waste removing toxic ammonia and nitrites. Live rock and sand will do the same in your aquarium. On coral reefs, waves sloshing around mix air with saltwater causing dissolved waste to separate from the water creating foam, which often washes ashore. Protein skimmers do the very same for our aquariums. Creating a balanced eco-system that includes, herbivores, carnivores, omnivores, and detrivores (scavengers) is a tremendous help in keeping your aquarium clean and your water quality good. See our Clean-up Crew Packages. Good water movement causes more water to pass through the live rock keeping your aquarium cleaner.
