Group Buy - Ozone Setup

Now i know the group buy already happened, but hopefully you don't have them yet and are cranking ozone out I'd like to make a request. Could those who are using it take a before & after picture of a particular area of the tank, doesn't have to be the whole tank, but I'd like to see if a photograph can really capture the difference. And also some comments as to what you think the difference is if any, of course it may take a few weeks (months?) for any difference to be noticed, so I realize this might take some time :)

I just did a 30g water change today and I noticed my water looked quite a bit clearer and it got me thinking of your ozone folks, incase I want to be apart of that user base sometime down the line.
 
im curious , would one big down side to useing the Enaly be that you cant dial down the production ? i thought the idea was that you wanted to add just enough so the unit was always on and adding ozone.

with this one it seems you might just adding short bursts now and then because it runs at 300 mg/hr
 
Snarkys I believe that's the whole point of putting the controller into the system, the controller is basically a way to "dial down" the setup, in that it'll turn off the production if it gets too high, and turn it back on if it gets too low. While the more expensive units do give you a way to dial down, you'll still need a monitor to see how much is enough, not to mention what happens if something happens in the tank radically alters your ORP? Unless you test every day on the dialed down unit you could potentially cause some problems, where as the controller setup is the safeguard.

I think the effect is probably the same as far as your ORP in either burst or continuous mode, but the controller is the key piece of equipment that is needed to save your tank, so why not go with a cheaper unit that's not adjustable?

Of course someone who knows more on the subject can pipe up :)

i was reading that a constant stream of a lower amount of O3 will kill parasites and oxidise organics better than large intermittent bursts of O3

Enaly Ozone Generator
Model OZX-300U
Link to Specifications
This is the same brand of generator that Eric Borneman is using, and the one he spoke about at the recent SEABAY meeting.

any reason you got the one with the pump ? I'm trying to figure out if i want the one with or without the pump if i order it .

BTW its interesting to note that it says it produces 200-300 mg/hr on the link you have and then on this link it says 200 mg/hr
http://www.ozone.enaly.com/OZX-300U.htm

then on this link it also says 200mg/hr but in the chart it says it only produces 165mg/hr with pure oxygen pumped into it.

I ended up going with a 100mg/hr adjustable unit; have not set it up just yet. The reason I went this route is because I dont want to overdose the ozone in short-term bursts. My rational is that the ORP generally changes rather slowly; not rapidly in our tanks and I dont want to have the ORP levels jumping up too quickly. I'm seeing a shift of about 30mv between day/night with rise rate about the same as drop-off; the mean is about 320mv (non-calibrated). I want to shift the mean up to about 360mv so the max is 375 and the min is 345 with the same rise/fall rate. Without an adjustable unit I dont think I would be able to do this; still a little unsure on the effect ozone will have on ORP swing. (compare adding limewater with a peristaltic pump vs using a float switch/powerhead). Both will work; but the float/PH might add the limewater too quickly.

I think for the ORP setup you could go either way; I just wanted to go the 'more cautious' route. If you run the Enaly 300mg/hr unit I would set a more narrow ORP range to control; maybe bleed some of the air supply to the skimmer collection cup/carbon chamber.

Also remember that ORP is inversely proportional to tank pH; with low pH causing ORP to increase. So daytime ORP levels should naturally be a bit lower than night in tanks that have a pH swing. I know, I know, the ocean pH is stable; but we dont have open systems and pH generally does shift some (so you will see rise/fall over 24hrs similar to pH). If you want to balance out the ORP to have less rise/fall; running it timed for on during daytime might also be helpful.

I suggest that those that are going to add ozone/ORP control to their tanks should first run the controller as a monitor (dont connect it to the ozone) and record your levels. Once the unit is settled in for a couple of weeks and you know the rise/fall/mean ORP for your tank; start running the ozone at low levels. I would first start the controller to raise the ORP no higher than the average of your high/low; this will chop the low end off but not raise the night-time ORP. At least you will know that ORP is not being raised too quickly; and your low side will be eliminated. After running this for a week; shift the ORP up to be no lower than the initial "high". From there increase slowly to ORP levels between 360 and 375mv.

Doing a monitor run-in will also allow you to test the controller/probe and determine if the probe is fouling quickly. An increasing daily ORP level can indicate fouling or a bad probe (should not be a bad probe with new equipment). It will help to determine how often the probe needs cleaning (soaking in pH 4 buffer will work). Troubleshooting any issues with the probe/controller is best done before running the ozonizer.

I'm planning to do something along these lines; and have learned some things about the ORP levels in my tank before adding ozone. I have not run ozone yet myself so if someone else who is/has run ozone wants to comment or has better suggestions feel free.

JMHO/HTH...

good post RustySnail. My monitor probe does foul on a fairly quickly basis so I watch for this. Don't see any visible coverage, etc., but a quick dip in vinegar gets in back in order rather quickly. I also see a ORP swing much like yours.
 
Nice post Rusty, now if we can just get some useful (ie readable by the average person) instructions on how to setup up one of those monitoring things to a computer (without being terribly proficent in *nix or electronics) then we'll be in business! :D

Sep 6, 2005 UPDATE

I received confirmation Sunday from Enaly that the ozone generators had shipped from China. They said to expect 5-7 business days travel time.

All other items are shipping from a Southern Cal wholesalers and they should ship this week. Hopefully everything should arrive to me at about the same time. I'll let everyone know when I have received everything, and we can then workout geting it to you.

Marc

Just an afterthought, I'll be travelling on vacation Sep 22-Oct 9. So I will try to make sure I get to the Bay Area before I leave.
 
i got mine yesterday. its kinda funny , on the front it says its 300mg/hr , then on the back it says its 200 mg/hr and then in the instructions it says its like 160 if you feed it with pure oxygen.

i think these may not be as overpowered as people think.


btw i ordered mine from thier site for $43.99 but they charge like $20 shipping because it comes from over seas ... it really shipped out from newyork. should have cost like $5.

Watch out for enaly, their communications are poor and their shipping and packaging is very poor, I received one of these units all crushed, returned it to canada, (international shipping, customs etc.,) only to have them deny or not understand that they ever received it back. Marc, could I suggest that you check the package from china via DHL very carefully, even to the point of inspecting the units before reshipping. If they are broken, then return to canada is a PITA, make sure you have tracking numbers and insurance from the US Post office only. Just my 2 cetns.
 
I bought mine directly from Enaly, had it within a few days and had absolutely no problems with the shipping, etc. AND, mine came from Shanghai.

Marc, let me know how the stuff looks when you get it, because now I am curious.
 
9/7 UPDATE

9/7 UPDATE

I received confirmation this evening that the ORP controllers & air dryers have shipped out of Southern CAL. Looks like everything will probably be in early-mid next week...about the same time I'm expecting the generators from China.

Marc
 
9/12 UPDATE

I received some of the stuff in today. I'm still waiting on the air dryers, ORP controllers and ozone generators. But most of the "extra" things that people ordered arrived.
