Acropora is the genus that most reef keepers picture when they imagine a mature SPS tank: dense branching thickets, bright polyp tips, and a wall of colour that only comes from stable, well run systems. Within the genus there are hundreds of named morphs sold under collector names, and understanding what those names mean helps you buy with realistic expectations rather than chasing a photo that may not translate to your lighting.What a Collector Name Actually Tells YouNames like 'PC Rainbow', 'Walt Disney', 'Fire Truck' and 'Kryptonite' are not scientific classifications. They are trade names attached to a specific genetic...

Most reef keepers who want to move beyond soft corals and LPS eventually ask the same question: what SPS should I try first? Pocillopora is one of the most common answers, and for good reason. It is forgiving of minor swings in water quality, grows fast enough to reward patience without demanding perfection, and tolerates a wider band of light and flow than most of its small polyp stony relatives.Growth Habit: Branching With a BackbonePocillopora forms upright branching colonies with thick, verrucae covered arms rather than the fine, twiggy growth seen in some Acropora. This chunkier structure makes it more...

Most people who add a stromb snail to a reef tank have never actually watched one work. It burrows nose-first into the top layer of sand, plows a shallow furrow as it goes, and leaves a trail of disturbed substrate behind it. That furrowing action is the whole point. A stromb is not a glass cleaner or an algae grazer in the way a turbo is. It is a sand bed processor, and its job is to keep the top few centimetres of substrate turned over so detritus does not compact and go anaerobic.Strombus species, often sold simply as stromb...

Most reef tanks grow a thin layer of film algae and diatoms faster than most owners notice it. Glass, rockwork, and the sand surface all pick up a dusty brown or green coating within days of a light cycle settling in. Trochus snails exist to deal with exactly that layer, and they do it with a quiet efficiency that makes them one of the more useful animals you can add to a reef.Trochus snails, one of the grazers we carry for reef cleanup crews.What They Actually EatTrochus snails are grazers, not scavengers. Their radula (a rasping tongue covered in tiny...

Tap water is not reef safe, and in most cases it is not planted-tank safe either. Brisbane and regional Queensland supplies vary in chlorine or chloramine dosing, phosphate-based corrosion inhibitors, silica, and dissolved metals depending on the treatment plant and season. None of that shows up when you look at a glass of water, but it shows up fast in a marine system as algae blooms, skimmer overflow, or stalled coral growth. A reverse osmosis and deionisation unit, usually just called RO/DI, is the standard way to strip all of that out before the water ever reaches a sump or...
