Rock Anemone, Thanks but I think I'll hang on to it for a while. ;)

Marc, Thank you very much. The flow switch is by Aqua Logic (my chiller brand also) and the version I purchased is rated for up to a 1/2 hp chiller (Aqua Logic 1.5 inch Flow Switch, 15A, 115V for Chillers up to 1/2HP) in case I decide to upgrade my 1/3 hp unit. It runs $145. so it's not cheap but worth the cost. Here's a marketing blurb form Aqua Logic...

Flow Switches are used to cut off power to the chiller in case the water flow stops (such as a pump failure or during water changes). The Flow Switch prevents the water inside the chiller from become frozen and bursting the pipes: which will damage the chiller and cause leakage. The Flow Switch is installed in the plumbing system before the chiller and the switch is plugged in between the chiller and the controller. In UV sterilizer installations, the Flow Switch can be used to turn off the UV sterilizer and prevent the unit from over-heating. This Flow Switch is rated at 15 amps and can be used with chillers up to 1/2 HP.

Joseph's flow switch is available from Marine Depot here. I've been eyeing one as a possibility for my tank but nice to see somebody using one. As always, amazing acrylic work, Joseph.

Thanks. I have a Canon Digital Rebel but more importantly, I shoot most of my tank shots with the Canon 100 mm macro lens. This is a phenominal lens and can be attributed to my photo's quality. ;)

I am still catching up on this thread, but wanted to comment on this post. I have been eyeballing this lens for some time now, and just can't bring myself to pull the trigger on it. Maybe by the end of the year I will have picked one up :). But I will say that lens attribtes aside, your tank is awesome with any camera/lens :)

Since I got behind in my reading, I started about 8 or so pages back, so I am going to ask a "what is that" question :). What is the tall white canister just to the left of the flow switch. It looks like a canister filter of sorts, but I hate to assume :). Thanks.


and the chiller chamber project was/is just incredible, as always :)

Yes nice chiller solution.

That looks like the foot of a UV sterilizer to me. Course I am wrong all the time. Just ask my wife.
 
I'm guessing UV also:)

Weatherson: Just curious how the penductors are holding up and also inquiring as to whether you are still pumping air into the penductors every so often. If so, how often. I'm asking for purely selfish reasons as I'm looking into plumbing them into my tank and also looking at injecting air twice a day...
 
If he is still using the ozone, then I am unsure why he would also have UV. While they are not mutually exclusive, you typically don't need/use one if you have the other. But then again I did miss several pages when I jumped ahead to catch back up, so perhaps I missed a key piece in there somewhere. :).
 
Sparkss, Thanks and yes, that is a 40-watt Lifegard UV sterilizer. I do in fact run both a UV and ozone but because they do different jobs for my tank. The UV for killing any possible pests and the ozone for water clarification via oxidation of organics.

BigEasy, Thanks and you can let your wife know you were actually correct. ;)

Hop, The Penductors are still going strong. They do require periodic cleaning but what doesn't? ;) Do keep in mind that for them to work well, you need a good quality pressure rated pump to drive them. The orifice on them is something like 3/8" so they are very restrictive. I have the air-injection happening five times per day 9 AM, Noon, 3, 6 & 9 PM), twice for 2-minutes each and three times at 1-minute each.

Hey Joseph,

It looks like you are injecting air only during "daylight" hours. Is there a specific reason for that?
 
Absolute Reef, Thank you very much.

jnarowe, I inject the air through my closed loops/Penductors. These are off from midnight to 6 AM.

Joseph.

Actually IIRC UV will also oxidize organics (depending on the flow rating and strength they.. and I thought that they also produce minute amounts of ozone, but don't quote me on that :)) and ozone can be used for killing pests and pathogens (most consumer ozone generators have the same (or similar) UV tube in them as the lifeguard UV does..any generator that is a corona discharge one).

But that is niether here nor there, I was just curious :). It looks like it goes through a secondary chamber, possibly a DIY reactor. The media in it looks like phosphate media. How is that all plumbed together ? or am I just blind and not interpretting the picture correctly ? :) Thanks.
 
Wow, the chiller barrel is pure art. I am constantly blown away at the talent that some people have and in your case it appears to be a gift as well. I took two years of art school when I first started college and at one time I thought that maybe I had the talent to do stuff like that but thankfully one prof leveled with me and told me I didn't. So I transferred to engineering where at least I can make a living but I still appreciate work such as yours . Please keep on sharing your work, it is an inspiration.

Do you theorize that the periodic coral sliming (from the air injections) has helped you to reign in the AEFWs at all ? Reading your posts it just got me to wondering.. thanks :)
 
Sparkss, My understanding of the differences between UV and ozone is that while they are similar in their means of attack, they each achieve different levels of different duties. You are correct in that some UV create ozone but your recollection may be more related to the fact that there are specific ozone generators that do so with a shorter wavelength UV light than that used in typical UV sterilizers (~185 nm and ~254 nm, respectively). I have always run ozone (and always will) for its great ability to remove the water yellowing organic compounds. I began to use UV when originally attempting to battle STN back when I started the 240. I eventually got over that bout and have done so all the while utilizing both treatments. Now that my tank is thriving, I'm going to lean on the adage that if it ain't broken... ;)

As far as the air injection induced coral sliming helping to combat AEFW's, it may play a part but I don't hold it to any concrete evidence. I will, though, add some observations somewhat to this regard. First, the corals that the AEFW's within my tank (two specifically) most frequent are among those that do not slime nearly as much as most others. Second, unlike others, the population of AEFW's in my tank seems to remain in check and does not grow to the point where I have lost any SPS in years or show signs that they are transferring to other corals from the two. Whether this is due in part to my weekly blasting of the infected corals to remove the AEFW's to be eaten by several fish, the predator inhabitants or the air injection, I do not know. But I do know that all or some of these actions have kept their populations in check. I remain optimistic that as long as I can keep this going, at some point in the future, there will be a natural or chemical solution available. My fingers are crossed as total tank breakdown is not an option... unless of course an upgrade is eminent. :D

Cuby2k, Thank you very much for the kind words. But, I will add that it's hard to go wrong artfully with shiny objects. ;)

Joseph.
 
gotcha on the 'zone and UV.. thanks :)

And I share your hope for an AEFW "cure" sometime in the near future. We don't currently have them (any more), but paid a heavy price for that. I would like to think there is a cure out there somewhere so that the fear of another infestation won't be such a disaster any more. :)
 
I know I missed this but if someone could direct me to the page or weatherson would you re-explain how you inject the air to the penductors on a timed schedule.
