Ozone and phytoplankton

[Fishy888]

During my research on ozone I read Randy’s article on ozone. It seems that as long as I use it at the minimum value needed to clear the water it shouldn’t sterilize anything.

I’m running 100 mg/hr on approximately 150 gallons of actual water volume through my skimmer for now. I hope to build a skimmer like @paul B’s eventually so my ozone contact time is longer and more efficient. Then I could drop the amount of ozone generated.

I just started culturing phytoplankton (Nannochloropsis) today. I assume that my ozone won’t kill my phytoplankton but I’d like to make sure. Of course its purpose is to feed pods and coral so it shouldn’t last long in my system but I want it to be live long enough to be eaten.

I must admit, it’s hard to NOT be a Paul B. fan considering how awesome his reef is and how long he’s had it. Besides, if I can run less ozone and get the same results, it’ll be better for the environment, our animals in and out of the tank and for my wife and me.

I’m pretty sure that, having read @Randy Holmes-Farley’s ozone article, my phyto won’t be killed but I could be missing something. Please let me know if I’m right on this please. I appreciate it.

I think it unlikely that ozone not used in a dedicated reactor with pretty high doses will kill significant amounts of phyto.

Thank you. I appreciate your help.

The ozone concentration in the skimmer is too low to kill phytoplankton, but even if it did, it wouldn’t matter because it would have been skimmed out anyway.

That’s true too. I’ll have to turn off the skimmer and ozone to give my corals and pods enough time to eat to their heart’s content. I forgot that part.

I just ran across a post I did over 16 years ago mentioning Randy’s ozone article. Randy, you’ve been doing this a LOOOOOOOOOOONG time!

I really loved running ozone for the crystal clear water it produces.

I do too! It just can’t be beat! It doesn’t take much ozone either. Much, much better, cheaper and less messy than GAC!

You’re killing me here! Now I’m going to have to go out and get me another one! I need to check out your build and see what you’re running. I don’t think ozone is as popular as it was years ago.

lol, yes, it has been a long time. lol

FWIW, GAC and ozone have somewhat different effects. GAC removes organics.Ozone primarily makes them not absorb light.
