The Power Of UV..!!

So for the past 3 months ive had a night mare with my water, the tanks a 260 Vision, not near a window not overfeeding nothing, water changes done religiously on time and no messing abiut with it in general,
But as you can see its been bright green.. Firstly I thought it was a bacterial bloom and then didn't know so after using chemicals and 'Blacking' it out for 3 days ie; no lights and a covered tank it worked ever so slightly but still came back green, Even used one of those micro filter pads and still GREEN

So I decided to invest in a Uv Filter which I bought off the site from Jeff, Here are the results-

DAY-1



DAY-2



DAY-3



DAY-4



TODAY-



only 5 days have passed and as you can see the results its working very well,
Delighted so far and thinking of a revamp...

Great stuff indeed,
Love the 5 photo gradient

Well Stem have to say that post was fantastic!
Goes to show a picture paints a thousand words or in your case 5 pictures.
Was reading up on UV sterilizers and one article described them as "water cleaners" and described just what you have shown.
We need more posts like this one as it shows us exactly what different equipment actually achieves and I don't think anyone can argue with those results.
Well done!

That is amazing ! Great idea to have pictures day by day to see the improvement.
Did u figure out what is causing the green water ?

The cause of green water
Green water is the result of a bloom of unicellular algae, and is basically the result of two existing conditions — the aquarium is receiving too much light and the water has a high concentration of phosphates. Both of these conditions are necessary for algae, and neither alone is sufficient.
As was discovered, water changes did not solve the problem in this aquarium. Many tap water supplies these days have high concentrations of phosphates. And, some councel water sources have higher levels of nitrates than are found in established aquariums with biological filtration. Under these circumstances, water changes add, not reduce, the nutrients that support algal growth.
The solution was the UV sterilizer it kills off the algae rapidly as seen!

Cheers mate, Ye must have been a serious algae problem, I tried everything, but got the light and its going quite quickly,
So lets give it a week or 2 before real results start to show,

Agreed,
At first I thought it was the light and went from nearly 10 hours down to 4hrs of light, and no sign of movement then the 'excessive cleaning started..
I would remove nearly 40% every 4-5 days and Nothing! But now your post is making perfect sense to me, Ive adjusted my light at the moment to 6 hours per day and hopefully will move it back up to 8 or 9 in the following weeks,
Long live to Uv

great job in documenting the change!

Incredible thread! I use a UV clarifier myself but I had no idea they were this effective....delighted for you as I'm sure you were sick of having a luminous green algal bloom....thanks for the timeline photos! Brian

Great set of pictures documenting the use of uv - thanks for sharing

DEADLY

Thanks for doing the day to day shots I told yea it would work and it would be a great benefit to the site

NOW you can enjoy your tank, best of luck with it ste
