Product details
Sea-Lab 28 1KG Block is a saltwater aquarium additive designed to restore and help maintain calcium, strontium, and all trace elements at levels found in the sea. In practical terms, it’s used as a steady, automated supplementation approach for aquariums that need continued replenishment of these depleted elements. Sea-Lab 28 is formulated to work without being treated as a slow-dissolve/time-release product; instead, the block dissolves only to replace what’s been used up.
Features:
- Restores and maintains calcium, strontium, and all trace elements at sea levels, automatically
- Works as a supplementation formula intended to replace depleted elements
- Not positioned as a slow-dissolve or time-release product
- Described as being able to’t be overdosed (per the product’s stated formula behavior)
- Built around continuous element replacement rather than a one-time treatment approach
