http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=is-my-filter-working-#1 newbie here :) Just purchased a starter kit which included a Interpet international power filter. the filter has power as its buzzing but I cannot see that the water is flowing into the intake, there are tiny bubbles sitting on the intake grill so surely this is saying there is no flow. Thanks for any help Capt-kipper 2009-11-08 http://forum.aqua-fish.net/?topic=is-my-filter-working-#2 Remove the songes from the filter and check that the outlet pipe and inlet pipe isn't blocked. Once you are sure there are no blockages replace the sponges and switch it on again. mickey 2009-11-16
