HELP!

HELP!

I just picked up a 200mg/hr RedSea Delux and connected it last Thursday. I set the dosage low (75) as the probe has not completely aclimated and am injecting the ozone into a "T" in my Sedra air feed tube. I a using an ASM G5 skimmer (dual Sedra 9000 - 1 fit for recirc mod).

I woke up Saturday morning and smelled ozone in the air. I have placed carbon over the air outlet on the gate valve mod, but the collection cup lid does not have any holes on the top (only has the cutouts for the lid to attach).

I am using a simple small airpump to feed the ozone generator.

What could lead to this build up I am smelling? I don't even have the unit turned up very far. From what I have read, the ozone should dissapate in the skimmer prior to being released into the collection cup.

Will lowering the amount of air (by dialing down the airpump) help? It would seem that the amount of ozone generated is the same (75 m/hr) but the delivery will be slower.

Is there a mod for the skimmer to make it "ozone tight"?

Thanks
Chris

Hey Reefers,

After reading through this entire thread, I placed my order last night for the Sanders 50 mg/hr unit and the Milwuakee SMS 510 controller.

I run a 72 gallon bowfront reef with 20 gallon sump; my skimmer is the Deltec AP600.

I'm trying to decided between the 250 or 500 airdryers by RedSea? Which one? I read that a lot of people just within one week completely exhaust the 250. Should I then get the 500 or is that overkill for my tank?

I also would like to know, should I purchase an airpump to drive the ozone into my skimmer? As it is, my skimmer has a very stong suction as it's an Aquabee pump. If yes, which one do you recommend? I have read around and some airpumps say, ozone safe diagfram.

I have two whisper pumps the 500 and the 200. The 500 has a dial to control airflow, would these pumps be enough or do we need new type of ozone safe air pumps.

Lastly,
What about the air check valve that is ozone safe? Do we need to insert one of these in between the skimmer and the ozonizer? I just don't see the purpose of this, my skimmer never leaks water out this hole, then again my skimmer is always on.

Would the check valve be to prevent water backing up in the event of a power outage?

Do I really need the T connection so air can be drawn by the skimmer in case the air pump stalls?

I would think that with a T connection ozone would escape or is there a vaccum going on in there?

Man I'm sorry about all the questions but if you can help that would be totally appreciated.

Drill a hole in the collection cup lid and put some carbon on there!

Like I said in your other thread, I can lower my air supply or ozone supply and you will still smell the ozone to some extent if there is no carbon on wherever the air is going to escape.

Anyone want to tackle my questions???

Thanks,

[Doubledown]

Thank you RoR. So regardless of the amount of air or the amount of ozone - without carbon I am going to end up with excess leaking from the skimmer?

Do you feel that by drilling holes in the lid to the collection cup I would "force" or "lead" the air escaping from the skimmer out that hole and not through the normal vents? Or will I need to seal those normal vents and add the hole in the top?.


I haven't found one yet, but are there designs or plans for a DIY ozone reactor? Would a large diameter PVC pipe with a Maxijet, airstone and some carbon do the trick? What about modifying a Phosguard Reactor to inject ozone into and then out through carbon?

Thanks
Chris

Get the 500....last much longer between bead baking's

 

[mikeguerrero]

Bill,

I just order the 500 online... Now I looked at the Sanders website and noticed that they recommend 20-500 liter/hour of air to enter the unit.

Anyone want to recommend the perfect airpump for my setup? I currently own an old Whisper 500 with adustable knob but I don't know the specs.

I saw a the Dolphin airpump which puts out 150 liters/hour would that be enough?

My skimmer is the AP600 and that sucker has a strong air suction already.

The Luft Pump by Coralife....heres a link.......I got mine on E-Bay

http://cgi.ebay.com/Coralife-Luft-h...ryZ46312QQssPageNameZWD1VQQrdZ1QQcmdZViewItem

It was the best price I could find on it.....but look around you may find it cheeper........It's Ozone safe with a 7.0 PSI adjustable air out put

 

[Fred_J]

mikeguerrero -- That is the pump I use. The air pump should not need to be ozone safe since it is first in line. It pushes air through the ozonator. I bought the 500 air dryer because I had to renew the smaller one every couple days.

[mikeguerrero]

Bill,

I looked at the specs on that pump by Coralife, it's rated at:

Output Flow Rate: 1.34 cubic feet/min (38 liters/min)

Now if we multiply that by 60 to complete one hour we get 2,280 liters/hour.

All Sanders units are rated to receive anywhere from 20-500 liters/hour.

Wouldn't I be way off with this powerful monster air pump???

Trust me I saw that awesome pump and wanted to bring it home but I believe thats too much power...

Am I wrong?

Mike

 

[mikeguerrero]

Can anyone comment on what I believe is the wrong air speed on this Sanders unit....

Because if not, I'd love to get this air pump.... It's monster big....

IME - Yes, no matter what I do, I get the smell of ozone if I do not put carbon on top. I think the air will follow the path of least resistance so I wouldn't worry about sealing off the collection cup. I just built my own reactor like a 4" snailman skimmer - minus the collection cup. On top I just put a female adapter and plug and then drilled a hole in the plug for my airline to go in and for air to escape. Pretty much anything that is ozone safe that you can inject air into will work.

 

[Bill and Elaine]

the luft pump has an adjustable air speed........mine pushes through the air dryer then the ozone generator then to the skimmer........you have to take into account head pressure....even for air flow........my pump is pushing air through all of that with about 7' of air hose

I have a sander 50mghr unit and thats what I use . Have been for 8 months now . Dialed up to allitle over half.

 

[mikeguerrero]

You guys are the best; clkwrk, Bill and Elaine, Fred_J.... I will purchase that air pump tommorrow....

Mike G

 

[jay24k]

Are all units about the same? On my calcium reactor I ordered, I had the guy get me the orp/ph controller combo all in one since I figure I'm going to do the ozone route.

Clkwrk, do you fell the 50 mghr unit would be plenty for a 180 gallon sps tank?

 

[clkwrk]

Sure would IMO . I have never run more than 15mghr and my orp stays right around 400 unless I am feeding or dosing kalk.

I also run a 250g airdrier . When it saturates I will use 30mghr to maintain.

 

[clkwrk]

as a matter of fact I will be using it on my 180 once I get it and get it going .

 

[jay24k]

Thanks. Might have to pick one up. Any place you recommend?

Thanks.
