Marine pure in Refuge?

Has anyone used marine pure block in their refuge? Got mixed results when I researched it online.

You could also use something called Pond Matrix I have heard good things about. It's just porous media that the bacteria colonize.

I have one that sits under my ball of chaeto and next to about 20lbs of live rock. It's in the lowest flow part of my sump. I have only had it for about 2 weeks so I can't testify to results, but I can't imagine how or why it would work any differently there than anywhere else. I also think that it must be a fantastic home for the smaller copepods.

I have it covering the entire bottom of the fuge area in my sump. I had rock rubble previously and went with the marine pure when I rebuilt simply because it has much more surface area.

I have my sump filled with marine pure and pond matrix. I made with baskets out of eggcrate to hold it. I swish them around in old tank water every now and then to get rid of surface crud. Not sure thats needed.

In my experience, if you are wanting to utilise M.P. for de-nitrification in particular, then treating it as a deep sand bed is the only way.
Never remove it to try & clean it. Microbes & macro critters like worms, feather dusters, pods etc, will keep it clean & will make a home of it.
The fact that these organisms will populate the block is what will make it more efficient.

Also, monitor aluminium levels, or increase water change volumes.

Thanks. I'm think of just lining my refuge with it instead of mud.
