Is cement toxic to fish?
Why is concrete/cement toxic to fish? Lime is a major component of cement and concrete. It dissolves easily in water (water soluble) and drastically changes the pH of water increasing the alkalinity (pH 11-13), which causes burns (just like an acid burn) on fish and kills fish and other aquatic life.
What kind of concrete should I use for a fish pond?
If you are in a climate where the soil doesn't freeze in the winter, then a 3000-psi mix design is possible. Using ready-mixed concrete would save you some work, but you can buy 5000-psi cement in bags at the Home Depot. My suggestion is that you reinforce your new pond with 3/8-inch rebar (referred to as #3 bar).

What is the difference between concrete and sand?
In general, the concrete mixture used for blocks has a higher percentage of sand and a lower percentage of gravel and water than the concrete mixtures used for general construction purposes. This produces a very dry, stiff mixture that holds its shape when it is removed from the block mold.
What is concrete mixture used for?
In addition to the basic components, the concrete mixture used to make blocks may also contain various chemicals, called admixtures, to alter curing time, increase compressive strength, or improve workability.
What is a concrete block?
Concrete block: Is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs 38-43 lb (17.2-19.5 kg). In general, the concrete mixture used for blocks has a higher percentage of sand and a lower percentage of gravel and water than the concrete mixtures used for general construction purposes.

Soft water generally has a lower pH, and you may need to use a buffer additive to prevent pH swings. Hard water tends to resist changes in pH, but the pH may generally be high. You may need to also test water hardness and alkalinity, along with pH, to get a true sense of the water's chemistry.
