We have a smaller water table, and we usually use Bromine tablets to
serve the purpose of keeping the water at least somewhat sanitary
throughout the day. We replace the water daily. We will also run bleach
through the system weekly, for about an hour, to prevent slime/sludge
build-up in the pipes and hoses.

Generally been working well for us, but if someone's got a better
approach, I'm interested in hearing what others do, as well. My concern
has been the bleach-it's slowly, but surely, fading the rich yellow
surface to a pale yellow. A non-bleaching chemical would be best.

Thanks!

I'm looking for information about how you treat water in your water
exhibits.  


Do you use chlorinators to deliver chlorine?  

How often do you test the water for chlorine?

Do you use ozonators?

On average, how often do you replace water?

Is there something really important you'd like to share?


Thanks!

Josh Larson
