Can I use chicken wire to reinforce concrete?
Concrete reinforced with chicken wire or hardware cloth yields ferrocement, a versatile construction material. It can also be used to make the armature for a papier-mâché sculpture, when relatively high strength is needed.
Is concrete toxic to fish?
Why is concrete /cement toxic to fish ? 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.

Brand new cured concrete might be relatively waterproof for a little while, but it doesn’t take long at all for water to penetrate the surface and begin to cause deterioration.
What is concrete fish pond?
Concrete ponds are used for intensive fish farming; concrete walls/banks eliminate erosion due to currents caused by mechanical aeration, waves generated by the wind and fish activity (notably nesting behaviour). This type of pond is smaller than earthen ponds and should not exceed 1,000 m2 surface area.
Do you need to seal a concrete pond?
A concrete koi pond adds interest to the landscape by providing habitat for these colorful fish. However, concrete is a porous material and can eventually leach lime and other chemicals into your pond unless you seal the pond with a waterproofing compound.

How do you neutralize concrete?
OSHA: Consider using a mildly acidic solution such as diluted vinegar or a buffering solution to neutralize caustic residues of cement on the skin. National Precast Association: To help neutralize the alkalinity, add vinegar, citrus, or a buffer to the water.
