API Reef Master Test Kit tests for four important factors in a reef aquarium:
- Carbonate Hardness (KH).
Monitoring calcium levels will allow you to replenish this vital element for strong and healthy coral growth, whilst the phosphate and nitrate levels can be studied to avoid any water problems.
The kit comes packed in a sturdy plastic case to protect the equipment when not in use. It includes 4 test vials. 6 test bottles, a holding tray, syringe, colour chart and an instruction booklet.
