I'd appreciate if anyone has a source of foam for making a HMF filter.
I have found the perfect foam (Poret) from Swiss Tropicals, but do not want to pay international shipping (USA).

I want a block but what I can find is too course, and the fine foam I can only find in sheets. Worst case scenario I simply buy sheets and build up a block. But I will have a good hunt first 🙂

I am after:

material: aquarium and shrimp safe foam suitable for HMF; which research shows is any open celled, polyethylene foam. 30ppi density is preferred. Up to 45ppi is acceptable.
shape: Rectangular block
dimensions: not critical, around 12" x 6" x 6" (give or take few inches).
colour: black (to match black hardscape)
 
I know I'm being very picky 🙂

At an educated guess, that stuff you linked to is courser than ideal. Impossible to say without a ppi (pores per inch) rating. I actually calle dup Kettering Koi earlier today and they said there stuff was way too course for fry\shrimplets. Shame as the shapes are pefect.

I will probably end up going to an LFS and buying a sheet of something, that way I can see with my own eyes how dense it is.
 
Looking forward to the shrimp rack haha 😛
 
That is a shameless off topic post. tut tut. :lol:
Same as for other plants, with a couple of tweaks... just lower fert requirement. vital to keep it clean (shrimps). do not let it layer too much (trim it).
