DIY Ozone System

[Dr Joe]

DANGER!?! CHOMPERS eats danger for Breakfast....then has a little nap followed by a light lunch on the veranda, then it's off to therapy class were he teaches positive reinforcement ideology to fellow Ictheotoids (ictheotoid - A student of religion who fishes for compliments; also, ... e.g., The ictheotoids believed strongly that God is a fish).

Kinda makes you wonder when he actually has time for such great projects, huh?

I would have put something more meaningful here but CHOMPERS keeps being right. (I know...go figure)

The long term concern I have is the deterioration of the units physically when sealed in an enclosure, and the injection of these contaminates into the water column.

I'm gonna go with "fishes for compliments". (I have a video you'll be interested in.)

Uneployment will do that to you. I need to try a 14 page resume.

I'm right for a change? I think you're holding something back...

Considering the number of different materials, I guess I have the potential for a toxic waste dump on my hands. I can accept replacing materials as they degrade, but I'm not all that ok with turning my tank into a toxic waste dump. Which materials have the potential of releasing contaminants?

The ozonator on my pool uses nylon & pvc fittings, pvc pipe, vynil hose, and an unidentified plastic used for the injector/ventury. I assumed these would be safe materials (except maybe for the unidentified plastic).

Did you really use the 'A' word?! I really need to talk to your Professors. I thought that was extracted from your vocabulary when you started Engineering!!!

Your not comparing concentrations, contact time and surface area for offgasing between the two. The fish are "breathing" this 24/7/365, and have a shorter lifespan in which to recover.

Everything that normally doesn't come into contact with the ozone on the machine is suspect. The outer plastic case for starters. ABS & PVC are carcinogenic if degraded as are several plastics. The degradation takes place before it can be seen in some cases.

For long term use, pressurizing the air intake and isolating the exhaust should eliminate these problems.

The looked at the wallyworlds near me and they don't carry this device, so I can't tell exactly how to modify this unit.

Still, your experiments are note worthy.

Dr. Joe, the whole practice of engineering is founded on the A word . We're not scientists - we've already assumed the scientists know what they are talking about in the first place!

Still. Judicial use of the word is key.

Cool idea, but after reading the whole thread, it's a little scary. I'll stick with gravel vacs and water changes.

Dr. Joe are there any materials that can be used in the aquatic world that would not be carcinogenic to fish? Anything that would not degrade overtime due to exposure to ozone? I'm following this very closely due to the fact that I want something similar on my large tank build.

 

[necrocanis]

Also if you were to install a 24/7 drip/drain system would that negate any negatives?

 

[Dr Joe]

Nor necessarily carcinogenic, but causing illness, deformity or death.


Silicone & PTFE tubing are easiest to come by.

Here is one list that should help... http://www.ozoneservices.com/articles/003.htm

Drip systems 'dilute' the problems, at a high enough rate (comparable to W/C's) they're beneficial, but otherwise the fish have to live in it (elevated levels). I prefer drip systems for replenishment and the use of W/C's for removal of contaminates.
