Starting Ozone

A small dose is very effective at water clarity. I am am running a Sanders 25 mg/hr at half throttle on about 120 gallons TWV and it works great. I have been doing this since around 2005/2006.
 
Hmmm in my larger tank, even at the minimum setting with the output going into a XP1000sss skimmer, I smell something like swimming pool chlorine. I have carbon at the skimmer output pipe and in the sump..
 
you can put a bag of carbon on top of your skimmer cup,many brands sell a cup with a lid designed to hold carbon as an accessory.... it might be escaping out the top,as thats a pretty small skimmer. Mine is 6 foot tall and doesn't leak any ozone. but it has dwell time. In your case a reactor might make some sense

does it smell the same right out of the ozone unit?
 
I have been running my ozone generator into my large skimmer since about 1980 or so. It is 200mg/hr and it is always turned up as high as it can go. I don't use carbon.
My reef has SPS, LPS and all the fish are spawning. No problems yet.
You can see the thing on the wall on the top left of the picture. Just above and to the left of the boiler thermometer

 
It has a DIY venturi but it also uses an air pump and two water pumps.
It's a real Man skimmer, not one of thise Sissy skimmers
 
Main problem I'm running into right now is that I detect a slight chlorine smell in the stand and my ricordias close up after the ozone has been on about 15 minutes.

Zoas, LPS, SPS, are still at full polyp extension and the fish don't seem to are but the ricordias start closing up even at the min setting.
 
Yeah, I'm even using a beefy air dryer so I'm not sure what's going on. I have a large bag of carbon on the skimmer output as well.
 
Hello guys!

I"ve just started my new Red Sea ozone generator (200mg) in my 420G tank. The problem is that my Apex shows ORP=320 but the new Red Sea shows ORP=641!
Can somebody tell me how do I calibrate the ORP probes?

I eagerly thank you. With my best wishes.

The Red Sea probe (and many others) can't be calibrated. You can check them against a standard. In the case of 641, I think it's safe to say that probe is bad if your fish and corals are fine.
 
Thank you Bill.

Corals and fishes are fine!

Do you think it can be that the probe is new and need those 2 weeks to "aclimate"?
Or should I order a new probe assap?

Thanks again!
 
Mine reads that also but I keep it all the way up and don't pay any attention to the readings because I know they are bogus.

That is way too out of line, even for a brand new probe just dropped in the water. I'd replace it.
 
Well I have an ozone generator I was going to hook up to the system to see if better water clarity would have any beneficial effects. ORP ran pretty much between 340mV and 380mV or so, but generally at the lower end of that range.

A little less than a week ago I made the pappone recipe and started to feed it in the morning when I did the first fish feeding. I used repurposed frozen mysid trays for the cubes. So far I've added one cube per day after skipping the second day, wanting to see what the reaction would be from the initial feeding - looked for recommendations and cube sizes for feeding, but no one was really clear on that. System water volume is about 709L so I figured the small mysid cubes would be ok.

Hmmm? Not sure I need the ozone. Water clarity has never been better. I am wondering when I need to be concerned about the ORP reading though. How high might be too high or will this self-limit? I think Randy said if not adding "oxidizers like ozone" then ORP shouldn't be a concern, but just being cautious here.

You can see when the first feeding took place as it dropped ORP pretty drastically, but from that point on it's been climbing steadily. I used the reference solution for checking the probe a few months ago when the tank was commissioned and have kept the probe clean. However that doesn't mean the reading is accurate but it does mean the readings are relative.

After the feeding, corals have their sweepers out feeding from the water column. I have not use amino acid dosing in conjunction with the pappone. The recipe I used also does not have HGH and I used less sugar than the recipe called for. Recipe posted calls for 1tbs and I used 1tsp.

Guess I can only observe and see where this goes. So far only one coral may have reacted negatively to this. It was an acro that was always brown - growing but never colored up. Now it may be lost. However all other corals look pretty good and LPS really seem to be responding well.
 
I know ozone will break down ammonia but will it have the same effect on nitrates and phosphates so to reduce algae growth?
