Overview Nitr8 provides a concentrated consortium of live nitrifying bacteria that rapidly establishes and fortifies biological filtration in marine aquariums. It helps convert toxic ammonia (NH₃/NH₄⁺) to nitrite (NO₂⁻) and then to nitrate (NO₃⁻), supporting stable cycling, resilient biofilters, and healthier livestock. Key Features High-density nitrifiers to seed new tanks and boost mature systems Speeds cycling and helps recover after disruptions (medications, deep cleanings, power outages) Reef-safe for fish, corals, and invertebrates when used as directed Clean, fast-dispersing liquid with no dyes or perfumes Pairs well with Captiv8 carbon sources and trace regimens Directions & Dosing General Use: Shake well to resuspend bacteria. Turn off UV/ozone and remove filter socks for 12–24 hours after dosing to maximize colonization. Resume normal operation afterward. Dose into a high-flow area or directly into the bio-media chamber. New Tank / Post-Reset (Day 1): 5 mL per 25 gal (95 L). Add an ammonia source (light fishless feed or ghost-feeding). Keep temperature and salinity stable. Follow-Up (Days 2–7): 2 mL per 25 gal (95 L) daily until ammonia and nitrite consistently read 0 ppm. Biofilter Boost (After Media Changes, Power Outage, or Medications): 5 mL per 50 gal (190 L) once daily for 3 days. Ongoing Maintenance (Optional): 1 mL per 50 gal (190 L) weekly, or after large water changes, to sustain robust populations. Notes: Avoid overdosing ammonia binders during cycling—they can mask readings and slow progress. Test ammonia and nitrite regularly and adjust feeding/bioload accordingly. Compatibility Safe with reef fishes, corals, and inverts. Compatible with protein skimmers, carbon dosing, and trace programs; just pause UV/ozone for a day after dosing. Works with most rock, sand, and ceramic biomedia.

Overview Isol8:Zn delivers laboratory-grade zinc in a highly soluble, reef-safe solution designed to restore and maintain proper Zn levels in marine aquariums. Zinc is an essential ultra-trace element that supports coral coloration, enzyme activity, and overall metabolic health for SPS/LPS corals, clams, and other reef invertebrates. Why Zinc Matters Skeletal growth & coloration: Zinc participates in enzyme systems tied to calcification and pigment expression. Macro/micro-nutrient balance: Skimmers, carbon, GFO, heavy filtration, and aggressive refugia export can strip ultra-trace elements like Zn, leading to long-term depletion. Closed-system stability: Routine, measured supplementation helps maintain natural-seawater-like balance between ICP tests. Key Features Ultra-pure, reef-safe zinc in pharmaceutical-grade water Rapid mixing & clear dosing—no clouding or precipitation Compatible with calcium/alkalinity routines and other Captiv8 Isol8™ traces Calibrated for fine control—ideal for SPS-dominant systems and ICP-guided dosing No phosphates, nitrates, or organics added Directions & Dosing For best results, confirm Zn via ICP-OES/ICP-MS or a trusted lab and adjust based on measured consumption. Start low: Begin with 1 drop (≈0.05 mL) per 25 gal (95 L) daily for 1–2 weeks. Test & adjust: Re-test zinc, then increase or decrease dose to maintain your target (typically natural-seawater range). Maintenance: Once stable, maintain a steady micro-dose regimen rather than large, infrequent additions. Do not combine into one shot with other concentrates; dose separately into high-flow areas. Shake gently before use; cap tightly after dosing. Important: Every system’s uptake differs with biomass, filtration, and feeding. If corals show stress or you observe elevated Zn on a test, pause dosing and perform a partial water change. Compatibility Works alongside Ca/Alk/Mg supplementation, amino acids, and other Captiv8 Isol8™ traces. Safe for reef-safe fish and invertebrates when used as directed. Avoid simultaneous dosing into the same spot as high-pH additives (wait 5–10 minutes). Ingredients Ultra-pure zinc in purified water (laboratory-grade solution). Storage & Handling Store at room temperature, away from light. Do not freeze. Keep out of reach of children and pets.

Key Features ICP-driven micro-dosing to correct verified Fe deficits precisely. High-purity, reef-safe formula for sensitive, low-nutrient systems. Predictable concentration for manual or automated micro-additions. BluePrint-ready—integrates cleanly with Captiv8 schedules and other Isol8/Aragonite supplements. Doser-friendly for consistent, small additions after calibration. Directions Test first: Obtain a recent ICP analysis and confirm iron levels vs. your target. Calculate dose: Use the label’s dose-to-µg·L⁻¹ relationship against total system volume. Split corrections: For larger adjustments, add multiple micro-doses over several days rather than one addition. Add in high flow (sump/overflow). Avoid direct contact with coral tissue. Verify & maintain: Re-test on your normal ICP cadence; convert to a modest maintenance dose as needed. Do not exceed label guidance—iron is highly reactive at trace levels. Tip: Dose away from fresh GFO/resins and other strong adsorbers for consistent contact time. Best Practices Keep core parameters stable: Alk 7.5–9 dKH, Ca 420–450 ppm, Mg 1280–1380 ppm, Salinity 1.025–1.026, Temp 77–79°F (25–26°C). Log every trace addition; align with your BluePrint schedule and water-change cycle. If running a refugium, begin with very small doses and watch macroalgae color and growth rate. Avoid simultaneous additions with strong oxidizers; separate iron dosing from phosphate control measures to minimize precipitation. Compatibility Safe for reef systems when used strictly at trace levels per testing and label guidance. Works alongside skimmers, carbon, phosphate media (dose at different times), bacterial programs, refugia, and amino/trace blends. Not a medication and not intended for non-aquarium use.

Overview Lower phosphate (PO₄³⁻) precisely and predictably. Isol8:Elimin8 PO₄ is a high-purity, BluePrint-compatible liquid phosphate remover formulated for controlled reductions in modern reef systems. It binds free phosphate into easily exportable particulates, helping restore crisp water, better light penetration, and color while preserving stability. Key Features Fast, controllable PO₄ reduction — Tune nutrient levels without broad-spectrum “stripping.” Clean export — Converts dissolved phosphate into floc that’s removed by mechanical filtration/skimming. Low-nutrient friendly — Designed for small, repeatable adjustments to avoid coral stress. Methodology ready — Integrates with Captiv8 BluePrint schedules and testing workflows. High purity — Reef-safe when used exactly as directed. Directions Test first: Measure PO₄ with a reliable low-range checker. Start low: Dose per label for total system volume; begin at ½ dose for the first applications. Dose placement: Add to a high-flow area upstream of fine mechanical filtration (e.g., filter sock/roller) and a protein skimmer to capture floc. Iterate: Re-test after each dose cycle. Repeat small doses to “walk” PO₄ down to your target; avoid large single reductions. Maintenance: Once at target, switch to smaller, periodic doses to hold levels steady. Important: Rapid PO₄ drops can stress corals. Make changes in small increments, guided by testing and visual response. Best Practices Keep NO₃ modest and non-zero; balance N:P rather than chasing absolute zeros. Replace/clean socks, floss, or rollers more frequently during active reduction. Time additions when skimming is stable; avoid dosing immediately before adding fresh chemical media. Align dosing with your water-change schedule and record PO₄ trends to refine maintenance amounts. Compatibility Safe alongside skimmers, carbon, and bacteria programs; space additions from other liquid supplements. Use with phosphate adsorbers (GFO/resins) if desired—tune both conservatively to prevent over-stripping. Do not dose simultaneously with strong oxidizers.

Overview Maintain calcium and alkalinity with a single, time-tested method. Isol8:Ca(OH)₂ Kalkwasser is ultra-pure calcium hydroxide for preparing saturated limewater that gently raises Ca and dKH as it replaces evaporated water—often improving pH and overall stability in SPS/LPS and mixed reefs. Formulated for the Captiv8 BluePrint methodology and dosing via ATO, kalk stirrers/reactors, or manual drip. Key Features Two benefits, one solution — Adds calcium and alkalinity in balanced proportion by dosing limewater. Natural pH support — Consumes ambient CO₂ and typically elevates pH toward the optimal reef range. High-purity powder — Dissolves cleanly to make clear, saturated kalkwasser (no perfumes, dyes, or fillers). Flexible delivery — ATO reservoir, peristaltic drip, or kalk stirrer/reactor compatible. Methodology-ready — Integrates with BluePrint scheduling; pairs cleanly with 2-part/trace programs when demand outpaces kalk alone. Directions (Preparing Limewater) Mix: Add ~2 tsp per US gallon (≈8 g per 3.8 L) of RO/DI to make saturated kalkwasser. Stir briefly. Settle: Allow undissolved fines to settle; dose only the clear solution. Dose slowly: Add in a high-flow sump area, ideally via ATO or a controlled drip to match evaporation. pH watch: Keep display pH ≤ 8.5. If pH rises quickly, reduce rate or strength. Maintenance: Top off the reservoir with RO/DI and add more powder as needed; discard heavy sediment periodically. Do not add dry powder directly to the aquarium. Always handle as a caustic chemical; wear eye/skin protection. Best Practices Target core stability: Alk 7.5–9 dKH, Ca 420–450 ppm, Mg 1280–1380 ppm, Salinity 1.025–1.026, Temp 77–79°F. Keep the reservoir sealed to limit CO₂ ingress (which weakens kalkwasser). Dose primarily at night if you need extra pH support. If kalk cannot meet demand alone, supplement with Isol8:Ca (calcium) and an alkalinity component; keep additions separate and spaced. For kalk stirrers/reactors, maintain a thin layer of powder at the bottom; avoid constant heavy slurry dosing. Compatibility Works alongside protein skimmers, carbon, PO₄ media, refugia, and UV (dose in sump, not via UV chamber). Safe with amino/trace programs (dose at different times). Avoid concurrent dosing into the same location with alkalinity 2-part to minimize precipitation.
