It is going to depend on the heads you have. If you have Easy Load heads, then you want the norprene type tubing as it’s the most durable. There are different size tubing and different heads support different sizes. Ideally your pump would support LS17 tubing. If it were me, I would go from LS17 tubing to John Guest fittings and then use 1/4” RODI type tubing. For that combo, this is what you would need.
Several feet of this tubing. Each head needs about 8-10” but you want to have spare so you can swap tubing every 4-6 months or as needed based on how much water you are changing which impacts the amount of wear on the tubing.

LS17 equivalent tubing. Note, that is is for easy load heads that support LS17.
