Filter on filter off.

[newfishguy]

Our garden pond is about 1000 litres capacity. its been established for about 5 years. it is home to 6 goldfish. It has a pressurized filter system with a 11 watt clarifyer. In the sales i managed to get an identical filter system at a bargain price, ( not just for spare parts), it was handy for an instant swap of media and filters. However, the ballast on my original clarifyer died and i had to use the spare ballast as a replacement.
In a flash of inspiration, i decided to install the other system as an independent filter, albiet without a clarifyer. It has its own pump and outfall back into the pond.
At night we turn this filter off, my reckoning being that as it is an extra filter, twice the amount of water is being cleaned during the day. And therefore, being off at night (for about 10 hours) shouldn't make any difference to the bacteria. My wife disagrees...

I would agree with your wife.
First of all filters lie in my eyes if it says good 1000 it's only good for half or 2/3 of what they recomend.
Shutting it off the o2 will be deleted and you will start to add dead waste to the pond. Don't forget plants switch to breathing oxygen at night

Welcome to the forum. The filter bacteria need the oxygen to survive and perform optimally. A canister filter is especially vulnerable without flow. I was trying to think of a way for you to spin this without admitting she was right...drawing a blank.

Run filters 24/7! Otherwise be like, "let's not flush our toilet till it's been sitting full for awhile",

Thanks for replying. The filter says its good for 3-5 thousand litres, so i think just using the original filter should be enough. I will stop using the other filter completely. The pond condition was fine before i installed the second filter, and maybe even more so if i didn't turn it off.

Nice analogy. Will not turn off again.

Thanks for replying. i didn't realize that the bacteria would die overnight. I 'll remove the other filter, it was just going to be doubling up the filtering, but in reality it has probaby doubled up the algae bloom we have. Looking back we didn't have the algae before the second filter.

I would leave them both. I'm a firm believer that there is no such thing as too much filtration.

Many here have multiple filters. I can't see a downside to keeping them both.

 

[newfishguy]

Thanks for that. As you say there' s no such thing as to much filtration, what about uv. Can you overdo the uv in a system?

 

[Lisak1]

Personally, I believe any UV is too much UV. That UV light is killing every single cell organism in your pond that passes by. It’s useful for floating single cell algae, but that’s it. And what’s your left with is a lot floating dead algae, which guess what? Feeds more algae.

 

[newfishguy]

Thanks for your input. Do you not use uv at all?
