What is the Cichlid pH Dosing Calculator?
The Cichlid pH Dosing Calculator calculates how much pH adjuster to add safely to cichlid tanks. Water quality is the single biggest factor in aquatic animal health. Far more animals are lost to poor water parameters than to disease introduced from outside.
A well-cared-for cichlid usually lives somewhere between 8 and 12 years. They are an omnivore, so their nutritional needs shift with age, size and activity. Cichlid needs vary sharply by origin: African rift lake species want hard alkaline water and rockwork, South American species want soft acidic water. Most are territorial and need stocking planned to spread aggression. Keep an eye out for Malawi bloat, aggression injuries, hole-in-the-head disease. These are the conditions cichlids are most commonly seen for.

How does the Cichlid pH Dosing Calculator work?
The figures are based on commonly cited aquarist rules of thumb and safe parameter ranges for cichlids, scaled to your tank or livestock details. It is a starting point, not a verdict. Somebody who has actually examined your cichlid will always know more than a formula does.
Factors that matter
- Tank size and current stocking level
- Filtration capacity: which affects how much waste the system can safely process
- Feeding habits: since overfeeding is a leading cause of poor water quality
- Source water quality before treatment, which varies by location
How do you use the Cichlid pH Dosing Calculator?
- Enter the current pH
- Enter the tank volume in whichever unit you use (US gal, L, UK gal)
- Answer "How did you test?"
- Press Calculate, then read the result alongside the sources listed below
Bring the number to your next appointment. Vets can work with a figure and a date far more easily than with "he seems a bit off lately".

Before you rely on this
This calculation assumes a healthy adult cichlid with no complicating conditions. Pregnancy, recovery from illness, medication and significant age at either end of the scale all change what is appropriate. When in doubt, the safest move is to take the number to a vet and ask whether it fits your particular animal.
