Your backyard chicken who is allowed to free range will eat bugs, insects, and leafy greens. This is why pastured or free range chickens have darker yolks. The diversity of food sources going into the chicken affects the egg construction.
30C-34C is about 86F-93F! That temp will generally feel too warm for most people in a pool. A better temp that would suit more people would be around 27C-29C or 80F-84F. The water will still feel warm but still be refreshing when you're swimming. ... I think for 30-34 degree centigrade ambient temperature, the pool temperature should be around 81 F (approx. 27 degree C). This will make body feel fresh. For a ambient temperature of around 25 degree C and below, the pool temperature should be slightly higher at 30 - 32 deg C.
High pH is NOT always BAD! But, high pH is NOT always GOOD, either! The recommendation that swimming pools should be operated at pH levels between 7.2 and 7.6 is almost universal. This recommendation is enshrined in generations of pool books and literature. It's embedded in many state swimming pool codes. Unfortunately, for most swimming pools, it's also far from ideal.
