How do they work out I was thinking about getting a tominaga dive clean mini or a ovation 1000 internal submersible power jet,I like the style of these filters that have the spary bar outlet,I have a aqua clear power head and thinking about maybe putting the sponge filter on that as well, Can you buy the spary wand for any powerhead, My tank is full of live plants and Im about to add community fish in hopes of breeding,I'm also running sand as a subrate and wonder how it would do with this types of filters,I'm running a pengiun 330, aquaclear 30 and need something towards the bottom of the tank, I know sand doesnt do well with filters but will keep it mid tank,Also can you buy extensions for the intake of the hob filter to get it deeper in the tank?Thanks
