Does this kit include calcium testing?
No. Calcium is not included in the MCP Test Kit. For calcium, magnesium, and advanced reef parameters, step up to Red Sea's Reef Foundation or Reef Test Kits.

Is this kit good for cycling a new tank?
Yes — it's specifically built around the parameters you need to monitor biological maturation: ammonia, nitrite, and nitrate, plus pH and alkalinity for overall water stability.

Can I buy refills instead of a whole new kit?
Yes. Red Sea sells individual reagent refills for each parameter, so you only replace what you run out of.

Is this kit freshwater compatible?
No. The MCP Test Kit is formulated specifically for saltwater and reef aquariums.
