Pump-Fed Eazypod Additional Bio ?
Apologies as is a question I am sure has been covered many times before.....but have been unable to find suggestions via the Search.
Visited a pond today in desperate need of additional Bio. Currently about 1500 gallons with a high stock level all going through a pump fed Eazypod.
The chap accepts additional Bio is needed to get down his Nitrite and Ammonia issues and needs guidance.
Having had Gravity fed Nexus's in the past, I would have been comfortable to advise the best way forward.....but pump fed opens up more issues.
The Question...... If the Pod was raised high enough, would it be a simple matter of letting the 3" return drop into a home-made bio-chamber (blue barrel etc) via a long 3" pipe towards the base of the bio chamber, adding enough air via an air disk to aerate the additional K1and having an exit pipe at a suitable height to return water to the pond? Obviously The exit would have a K1 escape guard and the chamber would have a drain valve at the base for maintenance etc.
Any guidance and pics would be appreciated.
Many Thanks in advance!.

How often is the person cleaning the Eazy Pod? It does sound like the obvious answer is to add extra bio but that is going to take a little while to get up and running isn't it. More cleans and small water changes may help short term whilst the extra media matures.
What was suggested when I asked the same question a while ago was to fit a swept T on the outlet of the Eazy Pod and feed a small pump on one outlet and have the other outlet going back into the pond. From the pump you can then feed another filter and then that can gravity return to the pond. Just make sure the pump is a lower flow rate than the pump in the pond and also fit a float switch so the pumps can't empty the pond if there is a leak or one stops working. The idea is what the additional pump doesn't take from the T goes back into the pond so it's not an issue if that pump stops for what ever reason. I can't remember which way round the swept T goes but would guess you would use the swept entry to feed the additional pump and the straight through section to gravity feed back into the pond?
If you use a flexi rubber boot T you can have a play around with what works best can't you

Now thats given me something extra to consider for the customer. Thankyou.
He regulary cleaning, but certainly over-stocked for the 18 pathetic litres that a Pod holds! (Can't stand the bloody things! Lol)

Don't dis the Pod lol.
Not sure if it will make any difference but if you use K1 you can use 30 litres of media but K1 micro you can only use 18 litres.
Some say K1 micro is better for fines than K1 is. I've only ever used K1 so can't say if it does or doesn't unfortunately.

I had exactly that situation and used a pump fed easy pod before a vortex full of K1.
The key is height and sufficient drop.
The outlet of the second chamber dictates the water height in the pod, so you need to set the pipework highest point (or ideally second chamber outlet) to be at the level you want in the pod.

What is feeding your Eazy Pod Rich? From the photos it looks like it could possibly be a sieve of some kind? Also have you got an isolation valve on the inlet and outlet of the Eazy Pod for maintenance etc? Can you put up some more photos of your set up please as I would be very interested to see how you have done it as the way I was suggesting would require the Eazy Pod to be a fair bit higher than you have your one looking at the photos?

These are old pics. I`m running a combi drum now.
Basically it was a pump fed (compact) sieve, then falling under gravity to the pod and onto the vortex full of k1.
The outlet height of the vortex determines the water level in the pod.
The whole system returns to the pond under gravity.

Lol always too late lol.
So basically it kind of worked as part pump fed part gravity fed due to the different inlet and outlet heights?
Obviously it worked OK for you but it surprised me as I was under the impression that the Eazy Pod would have needed to be higher than it looks in your photos?

My pond is part in ground, so the drop from the outlet to the pond surface is not too high.

I’ve a similar situation,relying on a pod too much and needing to add more bio,I had thought of adding a skimmer to feed a shower,but I’m intrigued by the Tee idea mentioned above? At present my pod feeds a largeish top pond/veggie filter
Running heater at low temp?
Covering the pond with polycarb should be enough to stop water temps dipping below 6C for the most...
