another ozone question

[pecan2phat]

Hey Deltec experts :),

I am running a Red Sea 100 mv ozonizer that is dialed back to 50 mv to one of the Eheims on my 702. (the air intake tube is tee'd so that the pump is not starved) I was wondering if I tee off the ozone line and run it to both Eheims while dialing the ozonizer to 100mv, would this be safe in regards that each pump is pulling 50 mv evenly (give or take 10 mv)?

Or would you guys run a separate ozonizer @ 50 mv for the second pump?

Thanks.

I've got the same setup on my 702. I've got the 100 mV Red Sea connected to one side, set at +/- 40. I don't havfe it T'd off and it works just fine. I have it hooked up to my controller and it maintains the O3 just right in the tank. I would NOT buy another ozoner -- not necessary.

The reason I have the tee is because I noticed that the Eheim was a bit restricted in terms of air intake when the ozonizer was connected with a direct air line.

Also, I could not get my system water above 335 mv at any given time, hence the idea of running a total of 100 mv vs 50 mv.

Yes there is a restriction. I have the side with the ozone open more than the other side to balance them out. If you use an air cleaner/filter on the O3, make sure it is activated and free of dust, etc.

Hmmm, my system runs at about 450. I do continuous water changes, therefore the ozone doesn't vary much. When I do a larger change it goes down, but in a day or so, it's back up to 450.

how long do you guys run your ozone for?

[pecan2phat]

My ozonizer runs based on the controller value. So since I have it set to 380 mv, it's running 24/7 for now.

I'm ditto with pecan2.
My ozone is controlled by my controller. I try to keep it at 450.
