Try going in a dark room and burning a piece in a blowtorch, alcohol, or other pale-colored flame. How easily does it melt or burn? What color does your flame change to (if at all)? If you have a good oven thermometer, try to see at what temperature it melts and/or burns.

i didn't get to test it in a oven, but i burned it, it actually didn't burn it melted and got really hard and i squeezed it in tweezers and it like broke apart(similar to glass i guess)

I think it's glass fibres too. They can irritate your skin - be careful. L

My guess is its fiberglass filter material. The fiberglass is twisted into filaments which are wound around a plastic filter cartridge form. It looks like your filter cartridge is breaking down after a long hard life. Most pool or home improvement supply houses can supply a replacement cartridge for about 10 bucks or less. Measure the old cartridge forthe proper replacement.

. Unless it's a very old heater, it will not be asbestos. Probably ceramic fiber/wool or fiberglass.
