No one uses the Blue Foam mod?!
I sure do, with all kinds of carts (401, 510, 901, 801).
The marine-land-rite-size-u foam works for all except its too thin for the larger 801, for that atty i use a different foam product that comes in a block instead of a thin sheet. I chose a block that has a cell structure similar to the blue foam, a black foam product made by Hagen.
The pieces i cut are bigger than the pieces shown in the video. I make them about 2/3s as long as the cart, and wider than the cart opening so they have to be compressed along that dimension to slip them into the cart.
New foam can impart a bad taste, so prior to using it, I prep it by boiling in water for several minutes and let soak in clean filtered water for an extended period of time (hours). I might do that boil rinse a few times before drying and using for the first time.
The foam bits can be washed and reused many times over. I freshen them up by pouring freshly boiled water over them into a shot glass. This lifts all the old liquid out and visibly perks them up. I've yet to discard one.
This stuff is resilient and easy to work with. On a first fill of a cart, I drip into the cart, then slip the foam in. On a refill, I push the foam down a bit with a paperclip, drip into the cart, then pull the foam back up with a paperclip and plunge it a few times to get the air out.
Foam is a much better cart stuffing material if you ask me. Better at delivering liquid into the atty, easier to work with, and really lasts.
