poret foam

[rickztahone]

If you are saying it’s so goo I maybe try it then in my sump. I have there socks, k1 moving bad media and a place for 4" foam.
Are you using 30ppi ? Would you choose 4" 30ppi or 2" 30ppi and 2" 45ppi? Or 45 is too fine and might clog?

It has certainly been a while since I've had this setup but I believe I had both 20 and 30 in different stages. I had a sock for entry, fall over in to a poret section and then media and finally the return section.

Let me try to find something in my old thread to show you.

This was me working on the building of the sump:

took a while but here is a pic, albeit, a bad one because I forgot my stand blocks most of it:

I'm using Poret foam in Part I of my 2-Part Sump.
It's 2" poret... 2 sheets for each side for rotating during cleaning (clean one, shift the other one ahead).. I have 10, 20, 30, 45 ppi sizes. It's not in use yet, so the 45ppi may end up being unsuitable for the sump.. we will see.... But with the shipping to get it from Europe, I thought I'd just get all 4 stages. They are 12 1/4 wide X 10" high. THey are seperated by Eggcrate that is held to the glass with suction cups, but I don't think that was really necessary (probably overkill). Hope to put it in service in 2 months.. Just finishing up the 'fish nook' now (I'll start a thread on the fish nook soon).

that is actually a lot of foam lol. I would be very observant the first few months of having this up and running on how much build up takes place.

I have a similar setup with 10ppi, 20ppi and 30ppi pieces, I found that the horizontal arrangement once the bacteria is established and mature the foam sheds the mulm which I suck out at each QC. I haven't cleaned my foam in years.

Ricardo, Yeah, I wonder if I do have too much foam. I'll know once it's been up and running for a while.

James, Are you referring to Ricardo's arrangement as Horizontal, or my arrangement as Horizontal? It's a matter of perspective, so I really have to ask.

I am just concerned about the mulm that tends to accumulate on the really fine foam. Just something to mind I think.

The good folks at Swiss Tropicals thought that the 45ppm might be too fine for my design. I purchased it anyway, and will remove that stage if I see excess Mulm and Blocking...

[JamesW]

Sorry I was referring to Peter's setup in that the water flow is horizontal. I never saw a restriction in flow (water level higher on intake vs outtake) and after some settling in time the side of the foam touching the glass is mulm-free. It did take some patience and time (~6 months) for the mulm to settle and then flow the whole way through. Each WC I remove mulm from the side of the sump that has biomax behind it in your picture.

James,
Thank you very much for your feedback! Gives me hope that I've gone down the right path..
