LAKE MALAWI WATER GUIDE
What Water Parameters Do Peacock Cichlids Need?
Quick answer: Peacock Cichlids are Lake Malawi fish that generally prefer stable alkaline and hard water with no detectable ammonia or nitrite. The best aquarium water parameters also depend on the exact species and its history. This African Cichlid Water Parameter Checker compares your test readings with published general Malawi care guidance and identifies which values may need attention.
What pH is recommended for Malawi cichlids?
The Ornamental Aquatic Trade Association lists a general pH guidance range of 8.0 to 8.6 for Malawi cichlids. Stable conditions are usually more helpful than rapid chemical adjustments chasing an exact target.
What is a suitable African cichlid water temperature?
The OATA Malawi care sheet gives a general temperature range of 23 to 27 degrees Celsius. This tool accepts both Celsius and Fahrenheit and converts the reading before comparing it. Extreme fluctuations can stress fish even when the average looks acceptable. Check your thermometer and heater placement before making a substantial temperature change.
Why are GH and KH important for peacock cichlids?
GH measures dissolved calcium and magnesium related hardness while KH reflects carbonate buffering capacity. Malawi cichlids naturally live in mineral rich water. The published group guidance is approximately 12 to 18 degrees GH and 10 to 15 degrees KH. These figures are not universal rules for every individual species or breeding setup.
What ammonia and nitrite readings should you expect?
Both ammonia and nitrite should be undetectable in an established aquarium. A nonzero result deserves investigation because nitrogen waste can affect fish health. Confirm that your ammonia kit measures total ammonia or free ammonia.
How much nitrate is too much for an African cichlid tank?
The OATA reference suggests keeping aquarium nitrate no more than 20 milligrams per liter above normal source water levels. That is why the tool lets you enter source water nitrate as well as aquarium nitrate. A target cannot be evaluated fully without knowing what the replacement source contains.
Can you use the same ranges for peacocks and mbuna?
This checker uses general Lake Malawi group ranges for peacock cichlids and haps and mbuna. Their behavior and feeding requirements can be quite different even when water chemistry overlaps. Do not treat the result as a compatibility recommendation.
What should you do if several readings are outside range?
Start by checking your testing method and whether ammonia or nitrite is detectable. Correct an immediate water quality problem safely while protecting fish from sudden temperature and pH changes. For nonurgent hardness or pH concerns examine source water and long term stability first. Use the separate Water Change Calculator to plan manageable maintenance.

FAQs
What pH do peacock cichlids prefer?
A general Lake Malawi reference range is pH 8.0 to 8.6. Check requirements for your exact species.
What water temperature is best for Malawi cichlids?
General guidance is 23 to 27 °C with stable conditions.
Should ammonia and nitrite be zero?
Yes. Both should be undetectable in a properly established aquarium.
What do GH and KH mean?
GH describes mineral hardness. KH describes carbonate buffering capacity.
Is nitrate under 20 ppm always the rule?
Source water matters. The general OATA guidance uses no more than 20 ppm above normal source levels.
Can I change pH immediately to match a target?
Avoid abrupt chemistry changes. Verify the measurement and use species specific advice first.
