Mike Paletta Inline QT system.

[thejuggernaut]

Has anyone seen the recent youtube video of his QT system. He has it plumbed inline with his main system. He said in the video that because it flows through his ozone reactor, he isn't worried about introducing any parasites into his main system. I would be very concerned about something getting through. Although he has been in the hobby for a long time and has some very nice systems, I don't know if I would consider this a good practice. What do you guys think?!

I have a hard time seeing it worth the risk, however effective. He is also doubling his QT as his frag tank, and I don't believe in doing that either.

I don't know what advantage you get that way over running a frag tank on the DT & filtration's loop and running QT strictly downstream of the system. You gain all the benefits and keep none of the risk.

BUUUT... To each his own

Considering you need to dose enough ozone to raise ORP to a minimum of 800mv, and water retention time at that ORP for about 15 minutes, that reactor would need to be quite large...

Note the Black Mollie. This wont be for most people. Paletta said his ORP is over 600 coming out of that tank and you better know what your doing there. I'm a little worried that somebody watching this video will kill a whole reef tank. Your not going to just do a 1 probe setup and think that will work.

Bill... Did you take it that this little thing with a trickle going through it and some bio media was the "ozone reactor"? Something does not make sense and I wish I could see more about this setup. He must be roasting through some carbon to get the ORP back down. How does he ensure he stops all the residual oxidants?

 

[snorvich]

I would not do it. Risk/reward ratio.

Yeah, that was the way I took that reactor.

Several years ago one of the labs I was running asked me to look into using ozone to essentially do what Paletta is claiming. Once I crunched the numbers for sufficient contact time at the needed 800+ mv ORP, a properly sized UV made far and away more sense...economically, reliability, safety (for both critters in the tank and people in the room), ease of treating large volumes...

As some of you know, I use 6 feet tall, 6 inch diameter tubes for other things. If I made a reactor and filled it with media like the stuff in the video or something else, it seems like water would still only take about a couple of minutes to trickle all the way to the bottom. Then it would just pool down there.

How much water/per hour could you put through something like that and still feel confident that everything is killed? Also, going back to the original purposes of the tubes, how much water with zooplankton in it, could be similarly treated. There might be different amounts for parasites and plankton.

So what would it take to make something like this actually work, doesn't have to be ozone. I would think that if you could make it work 100%, I would think it would be good for LFS. It wouldn't kill disease, but it could help isolate it to that single tank in the system.

A properly sized and maintained ultraviolet sterilizer (UV) will do the trick with all the return water passing through it. Typical for a multi tank system such as done in an LFS.

 

[ca1ore]

Just seems like a 'solution in search of a problem' given how easy (and cheap) it is to setup a separate QT. However, I do run my frag tank on the same system as my man display and use UV to isolate it.

That reactor looks like a pressurized version. Water & pressurized air enter the top. Media in the reactor creates more surface area to aid in gas exchange. The water is forced up a tube from the bottom of the reactor creating head pressure. The increased pressure is supposed to increase the gas saturation level of the water. I used one of these reactors with a small arc type ozonizer in line with the air pump in the late 90's. I could never get ORP of the water that high though. I suppose ozonizers are better now though.

to me, the question is why? Why take the chance of allowing disease to enter your system? It's not that hard to set up a stand alone QT.
