Flow rate and filters in series vs. parallel

[JohnHuff]

My main pump is off now while I'm waiting to get my uniseal by mail. My new moving bed filter will be very simple. It will be a bucket with the inflow coming in at an angle some inches from the surface. The incoming flow of water will cause it to move around in a circle mixing it and it will also create oxygenation since it's splashing in. No need for an air pump. The media will be a bunch of free floating bioballs. Outflow is just a PVC pipe near the bottom. With this setup, I figure I'll get moving media and oxygenation. Mechanical filtration will be from 4 prefilters attached to the submersible pump.

Now that my main pump is off, I'm using my 100g/hour auxiliary pump for my 800g pond. This pump feeds a shower filter with moving media inside it. The water flow in the filter is adequate but the small pump also means it will take at least 8 hours to for all the water to turn over once. How long can I keep this up? Will the ammonia/nitrite levels be building up to danger levels anytime soon?

Second question. I plan to add another filter to this setup once my main pump is running. But I plan to add the new filter downstream to my bucket filter. That means that the water coming into the new filter will have gone through the bucket filter already. I'm doing this because I don't want to install another pump. But does adding this new filter in series make any sense?

John I think you will be fine with the smaller pump, just keep an eye on it and do consistent partial water changes. A cheap air pump would really help in exchanging gas build up.

Second question.

I am running 2 of my bio filters in line with a 1800 gal pump. My filters are the Savio versatile filters. I have been extremely happy with the setup. You will be adding more area for bio media which can't be a bad thing. I personably would do it.

Thanks for the reply.

I guess pond manufacturers still think ponds are a man's hobby because when I looked up Savio versatile filters, here are the pics I saw:

and

Either that or I'm missing the women that's supposed to come with my filters.

John that is why I have 3 of them

Actually the company has been very helpful when dealing with them. They stand behind their products.

I agree their marketing could use some work.

What does Amy think about that?

What does Amy think about that?

She is fine with it. I just tell her is it for the health of the Koi

 

[dieselplower]

What is the head height for the 100 gph to the top of the filter? It's probably pumping significantly less than that. And yrs I believe adding another filter does make sense.

Head height is 18 inches. The shower filter is compact and sits on a frame about 2 inches over the pond.
My question re. adding the other filter was whether adding it in series made any sense.
