The pH requirements offresh water fish can vary greatly by species. Certain African cichlids which prefer hard water thrive at a pH of 8.0, while soft-water loving fish like discus need a pH of 6.5, and cold-water tropical fish like goldfish like pH 7.4 water best.Chemical test kits usingcolor charts have a reso- lution of only 0.5, while a

Rechargeable batteries with inductive recharger

These models have up to 200 hour extended battery life to guarantee long operationin the field. When the batteries are low, you don’t have to worry about carrying a spare set with you—the batteries can be recharged with
