Andy's new aquarium - and the magic of a UV filter

Not our Andy, but a customer, Andy Bruce who wanted to write a piece for our website about his new aquarium.

Last October I took the big step of buying a Juwel Rio 240 from Weald Aquatics.

Dutifully I went through the Nitrogen Cycle and added fish carefully over a period of time. By the beginning of December my tank had finished cycling and everything seemed to be going well, until...

I think I overfed my fish and an algae bloom started! Initially I saw a slight blur in the water and thought this might just be normal, but over the next few weeks things just got worse.

And what I woke up to on Christmas day!

With the friendly help of Gary, Andy and Tom, over the next month or so we tried using both NT Labs Algae Gone as a flocculant and then Esha Protalon 707 anti-algae treatment. These and frequent water changes started to improve the water but as soon as the treatments stopped, the bloom would proliferate again! At this point I was starting to pull my hair out (and I don’t have much of that!).

Gary suggested an Ultra Violet Clarifier filter (UVC) made by Oase. This is a tube that contains an ultra violet light that kills bacteria and algae blooms and can help prevent other water based infections, a component often used in high-end drinking water systems. I was sceptical that after so many attempts to clear the bloom that a UVC filter could fix things for me, but I bit the bullet and bought one.

Installation was a breeze. A small submersible pump draws the water through the external UVC filter and back into the tank, just like an external canister filter.

The results ... wow!

After one day things were improving. I thought ‘OK don’t get too excited this might be a blip’, but after only three days ... crystal clear water, absolutely amazing!

In my opinion a UVC filter is a worthwhile investment that will improve the quality of your water and is a benefit to any new or existing aquarium.

To me, my UVC filter is the Kryptonite that kills algae blooms!

And lastly, once again a big thanks to Weald Aquatics for all their help getting me through this problem.
