A marine aquarium specialist walks through the practical feeding requirements of LPS and SPS corals — the difference in feeding strategy between the two groups, what each group actually captures and digests, the role of photosynthesis, the role of broadcast feeding, the foods that work, the foods that pollute, the feeding schedule that produces growth, and the four mistakes that turn a thriving reef into a starved or polluted tank.

A marine aquarium specialist walks through the practical reality of keeping the so-called "tank-buster" marine fish — what the category actually contains, why these fish fail in captivity, the species that genuinely belong in a home aquarium, the species that should be left in the ocean, the tank size and system requirements, and the four mistakes that turn a beautiful juvenile into a chronically sick adult.

A reef hobbyist with 15+ years of SPS experience walks through the difficulty tiers of small polyp stony corals — the species that are forgiving for the new SPS keeper, the species that are intermediate, the species that are advanced, and the four mistakes that turn a stable SPS tank into a crash.

A reef hobbyist who's been running mixed reefs for 15 years makes the case for the auto top-off (ATO) — what it does, why every reef over 30 gallons needs one, the failure modes that kill tanks, and the four mistakes that turn an ATO into a flood risk.

LPS corals are the workhorses of the reef tank. The husbandry is more forgiving than SPS, but the essentials of lighting, flow, feeding, and placement are what produce the growth and the color.

The coral that starts to lose its color is the coral that is under stress. Early identification and the right response can save the coral. Missed, the coral can be dead in weeks.

The protein skimmer is the most efficient piece of nutrient export equipment in a reef tank. Most skimmers, however, are not tuned correctly, and the skimmer that is not tuned correctly is a decoration, not a filter.
