What is the Catfish pH Dosing Calculator?
The Catfish pH Dosing Calculator calculates how much pH adjuster to add safely to catfish 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 catfish usually lives somewhere between 5 and 15 years. Diet-wise they are an omnivore, which shapes almost every feeding decision you make. Aquarium catfish range from 4cm corydoras to species over a meter, so confirm adult size before buying. Most are bottom-dwellers needing smooth substrate to protect their barbels and their own sinking food. Keep an eye out for barbel erosion from sharp gravel, starvation when assumed to be scavengers, ich. These are the conditions catfish are most commonly seen for.

How does the Catfish pH Dosing Calculator work?
The figures are based on commonly cited aquarist rules of thumb and safe parameter ranges for catfish, scaled to your tank or livestock details. Use it to know roughly where you stand and what to ask about, not to rule anything in or out on its own.
What changes the answer
- 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 Catfish 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
One practical habit: revisit this every few months rather than checking once. Catfish change as they age, and the right answer changes with them.

Before you rely on this
One number on one day is rarely the full picture. What matters more is the direction of travel: whether your catfish is trending steadily, drifting, or changing suddenly. A sudden change is always worth a call to your vet, even when the individual figure still falls inside a normal range.
