WT-CAL — Water-treatment media
Remineralization and pH stabilization media for process water.
See WT-CAL specificationsThe problem you’re solving
Marine aquaria and aquaculture systems need a calcium carbonate source with a low contaminant profile that does not disturb water chemistry.
Why this material fits
- Natural marine-origin aragonite, the same polymorph as reef skeletal material
- Iron oxide ≤ 0.04% and silica ≤ 0.6% on representative analysis
- Coarse and agricultural sizings available
Available particle sizes
- 1–3 mm coarse
- 0.2–0.5 mm
- Custom
Packaging options
- Bulk / ton
- Super-sack
Technical documents
- Technical data sheet (Rev 2026.1)
- Safety data sheet (SDS) — sent by our team
- Certificate of analysis, current lot
No kiln. No calcination. Less processing than conventional calcined lime.
Frequently asked questions
Which grade suits a live-rock or substrate application?
Sizing depends on the system. Confirm with our supply team — send your system details with a sample request and we will recommend a grade.
