Placement of UV lights.......

[kschew1498]

Hi reefers

Anticipating my 35W UV Sterilizer .......and was thinking how to connect!

Apparantly now I am using a Hailea 6540 (2880L/H) to run my Hailea Chiller HL-880CA (1HP, recommended flow rate 1200-3000L/H) through a 10 meter long (to and fro) rubber tube as my chiller is outside my balcony!

The pump is in the 3rd section of my sump where my return pump is......and the chiller return is back to the 1st wet and dry filter section!

I was thinking to connect my UV lights after the chiller??!! That means....water coming out of the pump...to the chiller....then to the UV....then to the filter.....Is it ok? Is that the most efficient way to connect a UV sterilizer??

Any advise for me?

you gotta judge...cos too fast a flow will render the uv pretty useless also...

this is a graph from my coralife turbotwister....

probably not as effective as what the graph depicts...but just for your reference

Thanks....but pardon my ignorance.....the flow rate determine what to be eradicated?

yeah...coz if the flow rate is faster, the killing power of the uv decreases ..

the slower the flow rate..the greater the kill rate..

just imagine...an crawling insect moving slowly through a fire...compared to a flying insect flying throught the same fire.... the flying insect has a higher chance of survival since it enters and leaves the fire faster

wat we want is to make sure the water that enters the uv chamber gets exposed to uv as much and as long as possible to make sure that the stuff get killed before coming out...no point sending the parasites in and out of the chamber for a mild suntan if the flow rate is too fast

Thanks bro.....I guess I will use the weakness pump....hahahaha ...mini mini one can right?! Think I will have to look at the specification of my UV light when it arrives tomorrow.

Thanks once again Really appreciate it!

hehe...yeah..u gotta strike a balance lor...coz too slow also not good...why? u may ask..

because if the flow rate is too slow, you can probably kill those parasites that go into the chamber very well...but the rest of the tank are full of parasites that are multiplying and hasn't been sucked by the pump into the chamber

too fast a flow rate or too slow also not good...

hope that your uv unit has a recommended flow rate suggested

no problem..you are welcome

bro, if the return from your chiller goes back into the filter section, part of the 'cooled' water will be sucked back into the chiller for cooling again. an only part of the cooled water gets pumped back into the main tank.

IMO, it won't be as efficient as compared to having all if not most of the cooled water pumped directly into the main tank while the inlet takes in 'fresh uncooled water' - hope u know what i mean.

u can do a little experiment by timing how long it takes to cool down 1 degree with different positioning of the outlets...

for me, the intake is 1 section behind the return pump section. the outlet is aimed at the return pump where most of the 'cooled water' will immediately be returned to the main tank.

ideally for me, the outlet should go straight into the main tank.

cheers...

Thanks Bro.....apparantly the reason why I place the chiller outlet to the filter compartment is that I want the water to be very very "clean" before returning back to the main tank from the return pump! hahaha..... "Kia Su" you know!!!!

Actually I was contemplating to have the cold water from the chiller back to the main tank through my second return pipe.........hmmm.......but lazy to connect! hahahaha.....

Anyway, will see how it goes.....till one day my hands are itche again, I will do that.....now after all the setup.....a bit tired already......currently concentrating to get the parameters right!

Cant wait to see my UV Lights!
