Ozone Question - Is my situation worth it?

[leewish]

Thinking of starting ozone on my FOWLR mainly for smell reduction (160g volume). Seems like I'm going through Rox 0.8 carbon fast and furious. I have an apex so ORP probe can be moved to this tank from my other tank. I hate changing the carbon as well (every 2-3 weeks in reactor) so thinking this is the way to go.

Couple Questions:

1. Any idea on how fast the desiccate resin needs to be changed out? Was thinking order some extra so no rush to bake it. Not ready for the 600$ dryer at this time.

2. Does Ozone reduce the smell totally like carbon?

Thanks in advance!

How long the desiccant lasts is dependent on three variables: how much desiccant material is used, how fast the air flow is and how humid the incoming air is. I just have three "batches" of it and store two in sealed plastic jars while one is working. Then, I just bake it to refresh.

Different types of carbons remove different amounts of odors. I don't know exactly how they would compare to ozone.

Over-ozonation is a real issue. I test my systems daily for residual ozone oxidants using a simple DPD chlorine test (but I read that on a spectrophotometer). ORP is only a relative guide to the amount of ozone oxidants in the water.

My advice would be to underpower the amount of ozone and inject it into your skimmer. If you smell any ozone in the cup, you are adding too much. Remember though, that ozone demand fluctuates with tank feedings, etc.

lets give this a bump. as I am kinda thinking the same. my thoughts and I could be wrong about Ozone. I n my case I was thinking of that to help with water clarity so I could focus my UV on parasites. IDK if its worth the added cost and space tho.

OP. lets us know how it goes.

I am using outside air. The desiccant lasts 2 weeks in summer and 5-6 in the winter.

I think the smell is gone, Even my skimmer output to a 5 gallon bucket isn't bad. I get about a gallon a day.

Putting significant ozone into a skimmer will make it not skim. So I use 2, One as a reactor and one for skimming.
I have pushed my ORP to 410 before but recently reduced that to 340 or so because I really don't see any difference in the tank. I did have an ORP probe fail low and saw the negative effects of ozone though nothing died before I caught it.
340 is safer because if the generator runs continuously at 30% is isnt going to hurt anything unlike having it at 90%. At least on my system.

You can use an ozone generator that uses uv to generate the ozone, no air drying required. Change bulb every year.

I use a small portable ozone generator I got from Amazon on my 20l. Not the most flexible gadget, but it works perfectly on my size tank. Basically its the corona discharge model with built in air pump.

I have different thoughts on ozone and different goals, but my .02$

I found ozone more effective when used once or twice a week for 5-6 hours vs 24/7 at lower levels. Now, if you are using it for parasite reduction you dont want to follow my method.

For DOC scrubbing it works magnificent. A periodic blast once or twice a week....done. I pulled my skimmer offline ages ago. Ozone box does it just as well minus nitrate reduction which I don't need.

I found the most effective level was if I put my nose up to the waterline I could just smell a trace of ozone. If I can smell it on my couch its way too high.

I also found contact method important. Run with an airstone in my sump or tank it did the job, but wouldn't phase a small but persistent dino outbreak I've been having. However, I recently tried running it through a venturi power head at night to turn the tank into a milky cloud of bubbles, and low and behold dinos were gone. So, obviously the extended contact time of brute bubbles met a threshold. I'm now getting a dedicated pump in my sump to do the same thing there. A skimmer plumbed into ozone would accomplish the same thing.

And yes, even conservative amounts of ozone will kill tank smell.

Do you know if you match suitable ozone generator for your tank? According to your water tank and CO3 you want, you choose right ozone machine, if you do not know how to do, maybe I can help you, we are a ozone equipment factory from China. or you can consult with local ozone water treatment engineer

Same here. I built a reactor for the ozone, and the skimmer has been gone for several months. I do run moderate level 24/7 though. Far less detritus build up in the sump than any tank I've had in the past, crystal clear water, leather corals don't shed as often, but rather just grow. No oily film ever. I feed food that is loaded with fish and krill oil. I kind of want to see if adding a skimmer after 9 mo the of not having one would do nothing, or pull out loads of gunk. My guess is do nothing. Ozone smell leaked out of 2 skimmers I tried, so that's why I built the reactor.
