Birdsnstuff Posted April 2 Share Posted April 2 Hi - I have adjustable HOB filters on two of my tanks. I turn them down to feed but I periodically turn them up and down just for the heck of it. I feel like it adds some variety in the environment for the fish and moves the water around in new patterns. I even turn up and down my sponge filter. Does anyone else do this? Thoughts? Video for attention. Betty the Betta 1 Link to comment Share on other sites More sharing options...
