Question:
How do I measure the amount of dissolved oxygen in a
feshwater aquarium?
Replies:
This depends upon many factors: 1. How much do you want to spend? 2. Do
you want a continuous determination or just a "spot" determination, say
daily or weekly? Do you want an instrumental method, or do you want a "wet"
chemical method?
An aquarium supply store may well have "field test" kits available for
periodic monitoring. If not, "field kits are available. You can start with
Hach Inc., but you can also find other vendors by doing a web search (use
www.google.com) and the search terms "dissolved oxygen water" or "dissolved
oxygen water test kit" or similar terms. Pre-packaged kits are a big
advantage over doing the determination "from scratch". You can find an
