IT'S ALIVE!! ALIVE!!
I was about to buy another power head to pump in more flow into some dead spots in my tank.. then I thought why not try to fix the damn thing then can save some money..
So I took it apart again, fiddled here and there and realised that somehow the ceramic shaft wasn't really placed properly or the part that needs to be screwed in was screwed in too tightly, resulting in a lot of friction thus the turbine won't flow...
So fiddle here, fiddle there, re-aligned the shaft properly... then ok liao...
Heng.. saved some money...
