Most of my experience with filters has been with HOB power filters. I usually try to hide the intake as much as possible with plants (plastic, live plants are in the near future!). Doees hiding the intake like this restrict the filter in any way and make it less efficient? Or is the mulm usually small enough that this is not an issue and it will work its way to the intake? My thought is that as long as there is good circulation in the tank, this would probably not be an issue. But would like to know other people's opinions/experiences on this. Thanks.
