Just wondering how many of us have UV units on our tanks.

Comments welcome.

UV units on all my tanks.

Units range from 11w to 36w

I am considering adding a second 36w unit to my main display tank, as well as a Nitrate Reducter (& controller).

also, considering getting a 4-5 phase RO unit for water purification.

UV = extra insurance

Yeah , i think if you do regular water changes ( eg: every second day ), theres shouldnt be a problem with the fish.
But sometimes im busy with study (uni) and only have a change to do water changes once a week, and this where UV prevent diseases and other bad stuff due to my slackness :P -_-

I installed a 9W system (vorton 4500) just over 1 week ago. The overnight difference was incredible, and I already perform 30-50% WC at least twice a week. After a 3 day absence from my tank i was further amazed at the water clarity. At first i thought i had a catastrophic leak the water was so clean.

Having a 285L bare bottom with potted plants means lots of light and reflection around the tank. My regular water changes kept algae levels low. The addition of UV has eliminated any traces of cloudy water, green spots etc.... and any concern i have of it returning.

I love this thing and the impact it has made on my tank!!

Hi Jim,

My tank is approx 285l. The UV system can handle heaps more than this, as it is also used in pond applications. It can handle up to 4500L and a flow rate of about 1500l/phr. I am pushing about 300l/hr via a canister and the UV and a second wet dry filter at about 400l/hr without UV.
It cost about $220 including globe. Replacement Phillips globe about $40 if i recall correctly.

A few others on this site have the next higher model the vorton 9000 (i think thats the model number) Will cost another 100 or so.

Got mine from the pond place at Granville, corner William and Woodville Rds - there is a member here who works\owns the place. I think the name was Derrick. Maybe able to give more specs \ info on the other units.

Haz...thanks Pal.....now a q'n.......i am thinking of putting the UV in-line with the canister ext filter.. a) is this OK???? b) if yes, then should it be before the canister or after the canister filter??? i don't want any good bacteria killed by the UV. What do you have???.....Jim

Howdy everybody. New to the forum. I just thought I would coment. I don't use UV on my tanks (yet) but I have a 3200 gallon pond that was having a problem with green water (no shade at all where I live). I added a UV sterilizer (Tetra Pond UV3) about 10 days ago. Now the water is clear and can actually see my fish. Thinking I should add to my tanks now (55 gallon planted discus and 30 gallon reef). Wonderful devices.

Hi All,

I use UV on my 4x2x2 and will be from now on. UV's help keep the bacteria count down and also zap any free floating algae which keeps water clearer.

Jim, put the UV on the out put of your canister filter, the theory there is that the water passing through the UV is cleaner/filtered and less gunk will form on the qautz sleeve reducing the UV's effectiveness a kill rate. Also putting a pre filter (sponge) on the intake of the canister will help from gunk forming too. HTH

Cheers,

Dee :)

Hi Oscar,

I have a 9W CoraLife UV currently on my 4x2x2 on the output of one of my Eheim Canisters. I also have a 18W Coralife UV, but it leaked when I installed it :roll: so I am waiting to get it fixed or a replacment 18W back from O/S. The CoraLifes arnt cheap but bulbs are pretty easy to get and the arnt too pricey. HTH

Cheers,

Dee :)

Hi Dee

Did you get the Coralife from Singapore?

I've actually been thinking about getting myself one of these.
If you got it from overseas did you have any problems with shipping etc.

Also are the globes from overseas or can you get them easily in Australia.

Thanks.. Oscar
PS. any import tax charged
