Bit of off the wall thinking;

Filter bacteria multiply more quickly as temperatures increase.

The water temperature coming out of the heater is higher than that going in.

Has anyone made a conscious decision to run their bio filtration post heater? Ok not particularly practical in every situation but there would seem to be an advantage ?

For a pump-fed pond, it's actaully the most practical position and is where I've just placed mine, also for the above reason... Of course if the ammonia isn't there in winter, the bugs aren't going to grow that much......

Hi Dave,

I would imagine if we do heat that the time that the filter could get the warmer water would be minimum as surly the temperature would soon even out and once the bugs do get going they can multiply very quickly in the right environment.

Good thinking though got me thinking about some things

Hi Gaz

Ive never measured the output temp of the existing HX compared with the pond so have no real idea of whether there could be a tangible benefit.

Hopeful of finishing the installation of a couple of spirals in the next few weeks which may allow a big of testing.

Guess there could be a downside if the heater was before the BIO and the water was too hot - it could kill the Bio activity, just a thought as it always pays to keep an open mind.

Hi Dave,

I love keeping an open mind just wish i had one that worked OK

Yes it is sometimes good to think outside the box and some good can come of it and thats why its always good to have a chat about these things.

I was just thinking as you was worried about the warmer water on the filters and what if the warmer water was to help them out more as we know when they are warmer they can multiply faster ???????????????????????

Hiya

Yes the thought was that warmer water would help the filter bacteria but the second brain ripple was that too warm could be too much....

Guess the acid test will be when I get the spirals in I can see how things look.

Must get a better thermometer though.

I think the water is passing so quickly through the heater that there's very little heat increase; given that even with a pump that's turning over the entire pond volume in 2 hours, it still takes 6 - 8 hours to increase the temp by 1'c, so I guess there's zero chance of the water being too hot... I'll do some measuring...

Davej

Hiya

Think it will all depend on the heater etc, with a 25kw gas boiler it doesn't take too long to pull the water up a degree.

Dave

fishy hands

i have my heater is at the start of my system and mt reasoning was like yours , but does it wqork , that i dont know ????

legin

I plan to put an aquarium heater in the filter of my quarantine tank where the filter is sited above and part of it, in the hope that a small body of water (in my man shed) will chill less than a pond full.
regards Nigel
