i have aquired a aquis 500 by aqua one it was second hand but all filter media was there, anyway there was no instructions so i kinda guessed at how it works, so connected it to my tank trying to use my existing filter as a doner, anyway i ensured taps were on and powered it up, big rattles and no water coming out
, so i see the primer cap on the top and decide to turn it anti clockwise lots of air stars coming out followed by lots of water
, in blind panic i tighten it up and CRACK
, so i turn it off now the primer cap just spins around, i turned it to the original position and turned it back on and NO LEAKS and filter working
, not really sure why its not leaking but i need proper instructions on how to fill it (prime it) and where i can get parts if at all and or do i need that part or can i just seal it shut? a little concerned its gonna start leaking when im not here and empty my tank of water
anybody help pls
