I would keep the filters running and just top up until you’re ready to do your repairs.

Filter biofilm definitely does not die off altogether in winter. It takes it a while to get back up to full...

This would be a terrible time of year to move fish into a temporary tank imo.
An unheated pond needs to be as deep and protected as possible to avoid temperature fluctuations and dangerously low...

Thanks for posting Dale, all my sympathies to you and all of Fred’s family xx

I will tell her on Facebook that you’ve all being saying happy birthday to her here. I expect she’s pretty busy with baby Jacob these days :)

I had considered it, but I’m not 100% sure I like the look of them. Plus, I actually want shade in summer but not in winter. A structure with slats I could change the angle of would be ideal. There’s...

I’m glad you got something positive out of the year Gary, despite the challenges you faced.

Let’s all hope for a better summer this year for everyone and everything other than the flipping...

I might finally get around to building the pergola I had originally planned over my pond.

The problem is I like the look of the pond being open really. But the fish could do with a bit of shade in...

Hi ruffers.
You need to leave your tap water overnight in an open container before checking the pH because it tends to come out of the tap with a high dissolved CO2 level which makes it temporarily...

We got the tragic news yesterday that Fred has passed away. See https://www.koiforum.uk/pond-construction-pond-build-diaries/27798-sad-sad-news-forum-rip-freddyboy.html

Oh no, this is terrible news :(:(:(

I think it’s safe to say that Fred was well liked by absolutely everyone on here. He was always incredibly friendly, positive and enthusiastic about all things...

Having a drum is a life-changing experience compared to any filter that needs maintenance on a daily or even weekly basis.
You won’t regret it!

The only danger is ‘drum complacency’- a condition...

Sounds like a pH crash with dead filters from your initial water tests.
‘It’s really important to keep an eye on KH all year round- in the summer it can drop from filter bugs using it up, and in the...

The cost of running 2 energy efficient pumps (a Flow Friend and an Aqua Forte vario) on my setup is absolutely tiny compared to the water bill and the costs of heating the pond and feeding the fish...

Yes, I use RO. A lot of people do, particularly in hard water areas.

It can help you to grow bigger fish with better skin at lower TDS levels, and a lower pH which has knock on benefits with...

Ive seen your pond and your koi Steve, so I know that you have some lovely fish, but that you also know what you’re looking for in a high quality fish. I think that’s probably what your problem is-...

potentially yes if you’re able to put enough of it there to soak up the tannins

Unless you heat the air in the greenhouse slightly so it is warmer than the water, you will always have monstrous condensation in winter I think. I suppose the question is does this matter. Aluminium...

If you can run the water through some activated carbon filter media then it would take the tannins out quicker than waiting for them to get gradually diluted out by water changes.

To denature cells the UV needs to be fairly near the water that’s flowing, so unless the slots of your bio section put the media in direct line of ‘sight’ of the UV bulb it’s unlikely it would be...

I have to say I would not personally want to rely on the dry-run protection built into a pump to save you in this circumstance.
Top end drum panels have level probes which do this for you. But if...

You really need pictures from above, not from the side, no identify koi breeds :o

I had this card from Cuttlebrook :D

Didn’t read this thread first time around- but having used an Eazypod (it’s now the filter on my quarantine tank)- it’s neither a good mechanical filter for ‘polishing’ the water as it lets fines...

I generally use pipestock for ordering long lengths of pipe, they will ship 6m lengths via Tuffnels so if you know what you want all in one hit then it’s a good way of ordering. However all the...
