Keep skeletal growth steady with laboratory-grade calcium. Isol8:Ca is an ultra-pure, stabilized calcium solution designed for the Captiv8 BluePrint methodology and test-driven reef keeping. It restores and maintains target Ca to support dense calcification in SPS/LPS corals, coralline algae, and Tridacnid clams—without adding unwanted byproducts or clouding the system.
High-purity Ca for sensitive, low-nutrient reefs.
Predictable concentration for precise manual or automated dosing.
Synergy with Alk/Mg—pairs cleanly with Isol8/Aragonite counterparts to maintain ionic balance.
BluePrint-ready—slots into Captiv8 schedules and ICP/spot-test routines.
Two sizes—355 mL for extended use and 1,006 mL for standard long-term dosing.
Doser-friendly—ideal for continuous micro-additions after calibration.
Test first: Measure Calcium (Ca) and confirm your target (commonly 420–450 ppm for mixed reefs).
Calculate dose: Use the label’s dose-to-ppm relationship for your total system volume (display + sump minus displacement).
Split corrections: If a large adjustment is needed, add in multiple small doses over 24–48 hours.
Maintenance: Establish a daily dose that matches uptake; verify weekly and adjust.
Add in high flow (sump/overflow). Do not mix in the same container with alkalinity, magnesium, or concentrated trace solutions.
Bring alkalinity (7.5–9 dKH) and magnesium (1280–1380 ppm) into range before fine-tuning calcium consumption.
Keep salinity stable (1.025–1.026) and avoid large, unplanned water changes that can swing Ca.
Time additions away from fresh carbon/resin swaps for consistent contact time.
If precipitation/film appears, reduce single-dose size and increase dosing frequency.
Record all additions; align with your BluePrint testing cadence and any ICP results.
Safe alongside skimmers, carbon, phosphate media, refugia, and bacterial/trace programs (dose at different times).
Works with two-part, kalkwasser, and calcium reactors; keep additions separate and in high flow.
Avoid simultaneous dosing with strong oxidizers.
