UV Sterilizer DT Plumbing

[bcarl77]

Putting the effectiveness of the UV Sterilizer aside (go to the other thread), it seems like the most effective use of the sterilizer is to plumb it from the display. Based on what we know about speed and turnover through UV to fight various parisites and bacteria/dinos (cyano) turning over all water in the system is one of the most important factors. Most of us have the UV plumbed either off a manifold or recirculating the sump water (raises hand), which inherently limits the UVs exposure to ALL tank water (refer to all of BRS's videos).

With that being said, who has plumbed a UV sterilizer directly off their display and how did they conceal it?

mine comes out of the last part of the sump

main reason being that its effectiveness will be reduced turbidity

I feel if it from the return or recirculating sump water technically both would have the same turn iver from the display tank.
The reason in math. So return gph will say is 500, sump volume 50 gallons. Recirculating pump gph 150. Zero net sump volume change. Every 1/10 of an hour you are achieving near total sump turn over. Because the recirculating pump empties bact into the sump has no net effect. Placing the pump in the Return section or before fuge would help with debris in the uv

I have a 80w Deltec UV plumbed inline qith mu return. All water that goes to the sumpnpasses through it before entering the display again.

deltec claims that because they use quartz UV lamps (in addition to the quartz sleeve) their UVs are twice as effective as other designs as quartz lets 2x more light theough than regular UVs.

in any event, the relevant fact is that for this unit they claim a radiation level of 33ul at a flow of about 1000 gallos per hour. I am running at about half that (measured with anninline flow meter) so getting about twice the radiation levels.

finally, it is important that it is plumbed after the filtration so that the quartz fleece is kept clean ans maximizes efficiency.

I used pvc elbows to hang it off the back of the tank. I just took a FTS (with my kessils full blue at the moment). In the far upper left you can see the mj1200 that feeds my aqua uv 57 watt sterilizer that hangs off the back.

Every uv bulb has to be quartz, because regular glass absorbs UV.

How did you hang it off the back? Did you make a bracket or was this mounted to the stand. Where does your water flow back into?

 

[dwest]

I was afraid you were gonna ask . Excuse the shoddy workmanship, but I’ll show a pic of the back. I’m going to try to find a link where another reefer and I discussed this. hang on....

hopefully this helps.

Has anyone had better performance regarding cyano/dinos when you changed plumbing to run it off the main display?

 

[SCHAULJ]

I have a bad case of the dinos right now in my reefer 350. Im thinking about running a UV from my main display instead of plumbing one permanetly into the lower cabinet, sump area. Im not really interested in running UV 100% of the time but would like to have one handy for a temp external application if an algae outbreak occurs, sick fish etc... Im wondering if flexible tubing coming and going from the uv would be better than pvc plumbing...

There are several accounts in the dino threads and my own personal experience that you getter better dino kill rate running in and out of display.

High quality tubing would work for short term. That’s what I did until I made UV permanent.

Could you hang the UV from the display some how? I guess you could mount to cabinet... and run the temporary tubes.

 

[lakai]

Plumb it to your return pump outlet so that water goes through it before going back to your display.

Yeah thats what im thinking. It will be an eye sore for a few days but... It would be temp. Not sure how to accomplish this just yet.

I would like to hang it from one side of my reefer 350. Drop the pump and tubing straight down into the display and run tubing behind the tank and have the return line dump water into the opposite side.

Has anyone had better performance regarding cyano/dinos when you changed plumbing to run it off the main display?

Yes. You definitely want to run in/out of the affected tank. I have a basement frag system that I have been adding tanks to, now up to 3 tanks and two sumps all plumbed together. Each time I added a new display, BAM, it would get hit with ostreopsis. (My fault, not running dirty enough to handle the new volume dilution.) I am about two months clean now since the last bout.

So here is what I witnessed: none of the old tanks showed dinos. Sumps were visually clean of dinos. Only the new tank had them in swarms. They are free swimming protists. They choose where they want to hang out. They are not going to hang out in your sump without light. Nor the overflow. Not even another mature display with light because there they have to compete with bacterial film, film algae, coralline, etc.

Yeah, it is a visual bummer, but hopefully it doesn't take more than a few weeks to knock 'em back.
