Maintaining optimal ionic balance manually becomes a grueling task as hard stony corals (SPS and LPS) mature and expand. The CR-100 replaces the volatility of multi-part daily liquid dosing by using pressurized carbon dioxide (CO2​) to safely drop the internal chamber pH, melting crushed ancient coral skeletons back into their raw, bio-available mineral states.\u003c\/p\u003e\u003cp\u003eConstructed from premium, heavy-duty cast acrylic, the CR-100 relies on an advanced \u003cb\u003ereverse-flow fluid layout\u003c\/b\u003e. The integrated \u003cb\u003eAquatrance 1200 recirculation pump\u003c\/b\u003e continuously pushes acidic water from the bottom of the 4-inch chamber upward. This configuration ensures that the CO2​ gas remains completely dissolved and distributed, maximizing contact time with the aragonite media while preventing the substrate from packing together into a solid brick. Complete with a modular screw-off lid, a functional bubble counter, and an integrated probe holder, this compact workhorse is the definitive upgrade for low-maintenance coral growth.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eAutomated Skeletal Supplementation:\u003c\/b\u003e Provides balanced ratios of calcium, carbonate hardness, strontium, and magnesium simultaneously.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eAquatrance 1200 Recirculation:\u003c\/b\u003e Keeps the internal water loop moving consistently to eliminate dead zones inside the media column.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eRecirculating CO2​ Geometry:\u003c\/b\u003e Recycles unused gas pockets trapped inside the upper neck, minimizing overall CO2​ bottle consumption.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eProbe Integration Ready:\u003c\/b\u003e Port allows a standalone pH monitor or controller probe to monitor internal levels without risking leaks.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eEffortless Plumbing Taps:\u003c\/b\u003e Employs industrial-grade 1\/4-inch push-connect fittings for precise incoming feed and outgoing effluent tracking.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDemand Handling\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eHeavy Demand:\u003c\/b\u003e 75 Gallons\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eMedium Demand:\u003c\/b\u003e 100 Gallons\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eLight Demand:\u003c\/b\u003e 150 Gallons\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CoralVue","offers":[{"title":"Default Title","offer_id":47322758447273,"sku":"OCT-CR100","price":438.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/4958\/0912\/files\/bf561a62ff623dc237ad7f173dbcfd5c.jpg?v=1786228134","url":"https:\/\/worldwidecorals.com\/products\/oct-cr100","provider":"World Wide Corals","version":"1.0","type":"link"}
