mines been running since jan 1 never opened it up yet still strong water flow clear water
Heres my question thou, even though the water flow is good, wouldnt it still be better to change and clean out the filter anyways?![]()
i would still clean it maybe every 3 months? or 4 months. depends on the load.
there great filters i have 14 tinfoils a giant gourami 24inch a 22inch silver arrow 24inch catfish a 22inch lungh fish a 12inch black shark and another 24inch cat fish in a 180 gallon tank and the water is still clear not opened filter since jan 1st do a 50% water change once a week feed twice a week
