I agree with all Frimley wrote, pump on the Nexus at 15-20% at most, close the bead down, put the K1 in a net in the pond, or even in nets in the bio section of the Nexus, no air required at the moment.

Nexus210
I see. The Nexus is more important? I thought the Bead filter is essential as the produce good bacteria!
I should turn off the Bead and switch the Nexus210 on and put it on 2 to see the quality of the water. But sometime, Nexus suck the water put of pound. Last time, it took 75% of the water. I was lucky to see that early morning to stop it. It took one day to fill the pound with tab water!
please see this picture that shows when the Nexus is taking the water out from back! It should take when it clean for few seconds, but sometime it take the whole water out!

Not 100% sure I understand what you are trying to say.
The nexus has got much more bio capacity than the bead has so leave it running and turn off the bead.
If you have a look on the Evolution Aqua website there are downloads for the various filters and they show you how to clean them etc.
Not sure about how you empty the bead but just guessing that the top unscrews and then you can tip or using a wet and dry hoover you could suck the media out of it. Tipping it out would mean disconnecting the pipework feeding it so you can lift it up etc. As I mentioned earlier I've only got a tempest which is a very basic version of a bead so maybe someone with a bead can help more there assuming it's not an EA one and you can find the download for it on the same site as the nexus downloads.
I've only got Eazy Pods which is basically just the middle section of your nexus and that when cleaned drains best part of 200 litres of water I think so your nexus will most likely drain double that if you do 2 boils and 2 flushes like you have to on an Eazy Pod.
On your pond top ups you need to be using either a dechlorinating filter or a liquid dechlorinator not just straight from the tap as the chlorine will kill off the bacteria in the filters and damage the fish too.________________________________________________

Hi Mo,
The main power consumers in ponds are:
* water pumps
* air pumps
* UV clarifiers
The majority of filters themselves are passive and don't take electricity (but require flow rate or air to maintain).
It's possible to only use the UVC periodically. In fact depending on the pond it's possible to do away with the UVC completely (I have run a mature pond for 7+ years with 5+ without a UVC and that pond is small and in full sun).
It is possible to replace water pumps using airlifts to reduce electricity usage. My existing 1500l pond uses a a variable water pump running at 50W or so, whereas my new pond that is almost complete is near 14000l and should only use 58W as it uses air to move the water and doesn't have a water pump. So the only energy being taken is the air pump. The alternative is to use a solar panel to offset the power consumption.
The newer pumps are "variable" in that they allow you to vary the flow rate and that varies the power consumption - the pump I have takes 200+W at full 100% rate of 20,000lph but at the rates I'm running it, it only takes 50W or so.
Air pumps are a special case. An air pump often moves the water in the pond to promote gas exchange and to provide more surface air for that exchange. In thunderstorms and low weather a heavily stocked pond can find itself with a low oxygen level so an air pump may be the only thing keeping the fish alive. Again it varies with the pond and the stocking. If the pond has a waterfall for example the agitated water helps.
The nexuses also use the air to keep the bacteria media alive.
Although it looks like you have some good suggestions.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

Good afternoon,
many thanks.
I am now running Bead filter and the water is clear and good. I am happy with the current electricity expense as I have smart meter to track it. Is that enough? Nexus is quite expensive and sometime suck the water of pound out! I turned it off.
You said, Blow Pound Air can be also switched off?
I also switched UV light off.

Just because you have got clear water it doesn't mean it's good as all you may have done is removed the debris and fines from the water by mechanically filtering it. You need it to be biologically cleaned which is more important as you can have gin clear water that's toxic to fish and murky dirty looking water that's biologically clean that is non toxic. The only way to tell is either do full water tests and see what the readings are or leave it alone and if your fish start dieing off in the next few days or weeks you'll know if your water is toxic or not. I know what option I'd be going for.
Personally I think switching off the nexus in favour of the bead is a bad idea as come the spring the bacteria in the filter media will be virtually non existent and going by other people's experiences on here getting the nexus fully matured again from scratch can take 6 months or more. If you remove the media from the bead and put it in a net in the pond or the nexus it will stay matured enough to put back into the bead in the spring. Even if you left the media from the bead in the shed to dry out and then added it back in the spring the fact that it will need to mature again won't be an issue because firstly the nexus is doing what it should and secondly you'll only be trying to mature a relatively small amount of media so it shouldn't take too long.
If you're concerned about the running cost of the filters then you are probably going to shit yourself if you have to buy a replacement pump some time in the future________________________________________________

Confused dot com or what!
It suddenly dawned on me that the controller you are referring to Mo is the Draco drop in drum that's sitting in the top of the nexus. That setting from 1 to 4 is related to how often the drum cleans not the speed of the pump! Not sure what it needs to be set to as I don't know enough about them to say what's what. The box in the shed with Aqua Forte DM 20000 written on it is your pond pump feeding the nexus controller and that's what we're all saying should be turned down so now does the percentage figures people have mentioned make sense?
Your system is a pump fed system which means you have a pump in the bottom of the pond that pumps the water up and through the nexus then gravity returns via the outlet of the nexus. It goes through the drum as it enters the nexus and that mechanically filters out a lot of the muck from the water leaving the bio media in the nexus the filter the toxic stuff out of the water.
I have read threads on here where people have a problem with their nexus dumping loads of water all of a sudden and from memory I think it is possibly something to do with the bio media blocking up but could be wrong.
Your bead filter looks to be an Evolution Aqua one so as I mentioned before have a look on the Evolution Aqua website for the instructions as they can be printed off for future reference and may help with the dumping water issue? That could also be related to the drum being set to clean too much but you'll need to speak to someone with a nexus that also has a draco drum.________________________________________________

Do you have a Nexus?
It is off now. I am thinking to turn off Bead filter, the UV light and the below pound air, but turn the Nexus210 on in wash time 2. However, I am not sure why after few hours sucks the water of pound out. It should take a little water when it wash the filter on the top! Any idea?

If you've turned the pump off that feeds water to the nexus but the drum is still switched on then as the water level starts to drop as it drains out of the nexus the drum starts to clean thinking their is too much muck in the filter. That's probably why you keep loosing water.
Let's get something straight. The Draco drum and the nexus are 2 different things. The nexus is a filter in it's own right and if you look on the Evolution Aqua website you will see there isn't a drum attached to it as that is a separate after market add on made by a different company altogether called Draco. So the controller you keep referring to being set to 1 2 3 or 4 is just the controller for the Draco drum that's sitting on the top of the nexus. For the nexus to work it needs the water to be pumped into it via a separate pump which is most likely the Aqua Forte on but it may or may not be pumping through the bead first and then the nexus, I don't know as I'm just guessing by the photos you put on here. It would make sense as having a 20000 lph pump just feeding the nexus is probably a bit of an over kill so that's why I'm thinking it's possibly going through the bead then the nexus? If that's the case then running the bead and the nexus together isn't costing anymore than trying to run one or the other?
I suggest that before you ask any more questions you look on the Evolution Aqua website and get the instructions manuals for the Nexus 210 and the bead filter. Don't bother looking for the Draco drum instructions on that site as they aren't on there. For those you'll need to go to the Draco website.________________________________________________

A drum is basically top of the line in mechanical cleaning without going extortionate (thinking RO filtering). It uses a small amount of electricity to power the controller and additional to rotate the drum - mine (a Draco Solum 16) runs the rotation of 12V so it's very low power consumption.
A drum does consume water to self clean the drum mesh. Every so often it will detect the mesh is blocked by the rising (or dropping) water level, it will then open the water valve to spray clean the drum. Once the rotation is complete it will shut off.
Typical water consumption depends on the manufacturer and the water pressure. I can vary the water pressure to reduce the water consumption during winter. A secondary way todo this is make the mesh screen holes larger (thus acting like a coarser filter mesh) by replacing the drum mesh. An expense but depending on the scenario may reduce water consumption and still not impact the water quality. I think my rinse is about 2-5l depending on the tap.
Perhaps a quick photo of the drum and inside of the nexus?
If the drum is PUMP FED - ie the pump is pushing water into it, then it is unwise to switch off the drum cleaning. A blocked mesh means an overflow where the pump will empty the pond by the water level rising and overflowing into the waste chute and not back to the pond. (it does this for the Draco Solum16 but I'm not sure of the exact configuration for the Draco 2 for Nexus.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)
