Did I miss where someone is using O-Tabs, or, where to buy them?

You sure did - http://www.otabs.com/

I first heard of them with my fishing buddies. That's how they keep the bait alive in the bucket all day

So I chased this down. My hydro store doesn't carry it. I went to a bait shop who does. Each 'tablet' comes in a small tin about 4 stacked quarters high, but they are only good for 1-1.5hours. Hows does that help?

I also temialedd the link you provided but have not heard back

That sounds funny… have no idea about the 1.0 – 1.5 hour use. Below is info from the mfg. Web site. Big difference between 1.5 hrs and 10 hours.

Otabs are a one time use tablet packaged in an airtight Metal Canister 1 ¼” in diameter with a metal lid and will keep from one season to the next or longer if stored in a dry place.

****Each tablet releases thousands of bubbles of oxygen when dropped into a bait bucket and work for 5 to 10 hours according to size and type of bait. http://www.otabs.com/about-us.html

O-Tab might last much longer than 10 hours because you have no fish consuming oxygen. Fish are busy little animals (like ants), high metabolism, high O2 demand and they consume a lot of oxygen.

Maybe O-Tabs moved, new phone number, new city, another state, who knows. Keep trying. Might ask the bait shop boss where you bought the O-Tabs how to contact the mfg. If the bait shop buys and sells their product there has to be a trail to the mfg. ends at his bait shop.

How much did you pay for O-Tabs at the bait shop? Bet they were pretty high there.

@J Henry thanks for the kind words.. I appreciate it.
I have a great deal of respect for your contributions. :)

$1.59. I didn't buy any as it would be a waste of money for <2 hours use. He asked me how big was my bait bucket, I said 2 gallons. That may be the problem compared to a small (<1g) bait bucket

I hope you are right and the bait shop owner is wrong. Digging into Otab site they say 5+ hours, which would be fine, 10 obviously better

Looked exactly like the one on
otab www.

Don't forget the additional 10% CO2 O-Tab produces along with the 90% oxygen... if you like or use CO2... that's a 10% free-be at no extra cost, like a little extra treat.

Behold some new avenues of basic chemistry to explore, I really like the new techy stuff, applying the cutting edge stuff solidly that is based in hard science and horticulture. Think beyond the boundries that other try to impose on you and thrive. "Show me, don't tell me."

Sure you can have 130% -150% DO Saturation in 80% nutrient solution if you like and your crop and good microbes shall thrive in an oxygen enriched oasis you have made. And this can be done cost effectively too.
Years ago my college Chemistry Professor told me, "Knowledge is only 1 click away, think big, be bold and never fear failure." He was absolutely right, I believed him.

Check these out.

Searched Amazon. The comments under similar items was helpful. Here's one, how does the Otab stay on the bottom of the rez?

The standard amount of oxygen which should contain in a fish tank is 6 mg of oxygen per 1 litre of water. Greater amount than this would be better..........

Begs the question... how much does roots need?

My rez is outside the tent, but my DIY bubbler is inside. However, I doubt that small amount of co2 would do much in a > 3 x 3 tent

How much do roots and plants need to really thrive? How much do all the microbial colonies need? And the big one - how much O2 is needed to inhibit fungal opportunist outbreaks?
The answer to your "big question" is 100% DO Saturation or greater continuously or even better is DO Supersaturation >100% DO saturation continuously.

Now you know the answer to "how much." The next bigger question then is how are you going insure continuous 100% DO Sat 27/7 for a growing season? Can't do this with air, now what?

Of course growers disregard all this stuff as meaningless and just hope the crop won't catch the root rot. If the O2 gets low and the root rot attacks, treat the disease with chemicals when the roots get slimy and deal with the little set-back.

Or blast with air pumps and use hydroguard and not worry at all

PhatNuggz said:

well, looking at the OTab video one Otab doesn't look like it 'saturates' much of the water in the vessel at all (just a few tiny bubbles heading toward the surface directly above it=not saturating), let alone > 2gallons. One would likely need many multiples to cover the surface area in the bubbler or rez

Seems like it is not cost effective, but I'm willing to listen

Looks can be very deceptive. What is saturated water? What does water that is saturated actually look like to you? What does water that is unsaturated actually look like to you? How can you really tell the difference between water that is saturated or not saturated by looking at the water?
All air bubbles look, smell and taste exactly like oxygen and nitrogen, a 90% oxygen bubble is very different than a 20% air bubble. It looks, smells and taste the same too.
Can you tell smell or see difference between air and oxygen in a hospital room? Maybe there is no difference and they charge you more of the gas that comes out of the wall outlet marked OXYGEN and it really only air. maybe you are being charges the price for oxygen and all your really getting in that O2 mask strapped on your head is only plain old air. You would never know the difference.

Cost effective? How much time, chemicals, dollars and aggravation does treating a full blown root rot outbreak cost? ... every time your roots get slimy year after year. Many, many growers prefer treatment and not prevention and that a matter of choice.

PhatNuggz said:

When the bubbles travel straight up, how exactly can they be influencing the surrounding water?

Click to expand...

Exactly like this – Google “Henry’s Gas Law” and "Diffusion"

PhatNuggz said:

How about showing us your grow using these?

Click to expand...

Showing you an image of supplemental oxygenation administration with a homemade packed column would be as alien to you as looking at fungi under an electron microscope, a waste of time and meaningless for you. OTabs are just a quick simply method of administering 90% supplemental oxygen and 10% supplemental CO2, that’s all it is.

PhatNuggz said:

I really want to try these, but....

You can buy chillers for ~ $250, which will outlast $250 worth of Otabs (from what I can see will only last a few months in a 2G tote/bubbler) many fold

Click to expand...

I hear you saying and understand – water chillers, cold water and air (aeration, 20% O2) is your oxygenation limit. Oxygen generators that generate 93% O2 cost about the same and expands your oxygenation limits exponentially. Is your goal cold water or preventing low oxygen crisis? If cold water provided plenty of dissolved oxygen and prevent low oxygen crisis, there would be no root rot problems.

PhatNuggz said:

Surrounding air is completely different than water. You are correct IF the room is sealed. If the room is open (no ceiling) the oxygen will escape rather than fill the room

Click to expand...

Yes, your right, ambient air is completely different than water (a gas and a liquid) and yes, gas molecules will diffuse from a higher tension to a lower tension whether the room has a ceiling or doesn’t have a ceiling. Google – “Diffusion”
