    K1 end of life?

    I have a Nexus 300 which I bought 17 years ago and it still has the original k1 that came with it, I was just wondering, dose it even need replacing with new, or does it just go on forever.

    Unless it's braking up, it will be fine. Never heard of it failing as yet.

    Mines 13 years old and still perfectly fine.
    I'm no expert, but providing it turns over in the bio chamber, it prevents waste build up on the stuff. In terms of good bacteria, if its got ammonia to munch on, and air it will thrive. I think the plastic will outlast me..

    K1 is an extruded High Density Poly Ethylene (HDPE) which is a thermoplastic polymer made from petroleum. The time it takes for full decomposition varies but is widely accepted to be between 450 - 2000 years. This means you've got a few years yet - just as well given the original price!
