Disolved Oxygen in our Reeftanks - Who else measures it ???

What is the best way to monitor dissolved oxygen today in 2024? Cheapest and continual monitoring

Just saw this thread, but don’t have time to read the whole thing.

The way I can tell if DO is high enough is to see if the fish are alive. If fish are alive and behaving normally, there’s enough oxygen.

I’m reminded of a stream-survey I did for an ichthyology class in college:

Me (while taking water temp measurements): ‘Hey, Dr Fish…should we test the pH of the stream as well?’

Dr Fish: ‘The pH of the stream is fine’

Me: ‘How do you know that?’

Dr Fish: ‘All the fish aren’t dead’

ORP is a must have for ozone systems. I've always ran it on my Apex classic but it was never on point. I'd just look at trends for shifts. My probe is from 2010. I should get another...

Good water quality, water movement and ph

Let’s say I want to measure it continually anyway since I plan on having a lot of fish that life in tidal zones.

I do not know if continual monitoring is plug and play ready for reefers.
