Can't Source a Replacement Bulb for my Blagdon Inpond Unit

[Mehitabel]

Hi,
I posted recently because the light in my Blagdon Inpond 2000 filter/fountain unit was shining brightly, but the water wasn't clearing. From some comments here, I decided the first thing to do was replace the UV/light bulb.
.............Which has turned out to be much easier said than done. None of my local aquatic gardening stores have the bulbs. In fact, one has stopped stocking Blagdon altogether and one is winding down. I can't find anything online. I see that Blagdon has been swallowed by some vast megacorp (I think they're called "Inpet") which of course has no customer service phone line. I'm tearing my hair, because my poor little fish are blundering about in opaque water..

Is it possible to buy UVC units separately? Then I could just use the Inpond as a filter/fountain...

Anyone else had probs with supplies just drying up (so to speak)? I was told by staff at one local pond centre that I won't even be able to use a substitute, because each manufacturer's parts are cleverly designed not to be interchangeable.

The pond is a pre-formed 750L job. Established about 12 years, with plenty of oxygenators and around 15 small fish. (Apologies for the lack of photos, but I'm also struggling with a laptop which won't let me open or post my own pics! - Not that an image would help much in this case.)

Sure, you could use a separate inline unit plumbed in: https://www.swelluk.com/pond/pond-filtration/pond-filters/pond-uv-clarifiers

Yeah either that or the parts are so expensive, you are better off buying a new unit after accounting for wear and tear.

Thanks! I've actually managed to find a compatible (I hope!) bulb at Complete Aquatics. Now I just have to trust it'll clear the water so I can find out how many fish I have this spring........

Just curious, but do you test you water parameters?

Apologies, missed the notification for this.

Yes, I do. At the moment, they seem fine. But the new bulb hasn't cleared the water. So now it's on to researching how else to de-green. Suggestions welcome!

Small bog next to the pond worked great for me.

To Bog Or Not To Bog ??

Just finishing up the waterfall/stream. It was much more work than I had anticipated ! Anyway, at present I have no real filtration save the pond itself. However have only a few goldfish. I am considering adding a bog for even clearer water. I have read many of the threads related to bog...

Wow, that's interesting! Sadly, the edges of my pond are slightly raised, because it's a pre-formed job and I couldn't quite get it flush with the ground. But there might be options; maybe I could cut away part of the plastic mould... Thanks!

Depending on your space and aesthetic, you could have a bog higher than your pond by using a separate container with a return over your pond edge.

Upflow gravel container bog added!

The pond has been a work in progress since i made my Intro thread here a couple of months ago. I've added fish, plants, and most significantly, a 100 gallon stock tank upflow gravel bog! The new bog is a 100 gallon rubbermaid stock tank with an undergravel manifold being fed by the pond's pump...

Adding a bog filter to raised pond.

Firstly, apologies for not updating this thread :) Running both the big ugly filter and bog together until I locate the problematic leaking pond issue. For now, switched to Bog only so I can see if the water continues to drop. Growing well don't you think? looks like peppermint are taking over...
