Anchor_fist Posted June 10 Share Posted June 10 I few weeks ago I found a bunch of plastic boxes for holding nails on clearance for $1 each at Walmart. Today I got the Idea to take one of them drill a hole in the bottom and pop the top of the outlet tube on my sponge filter. It works pretty well and now I have a media basket to put ammonia pads, phosphate pads, bio rings etc Link to comment Share on other sites More sharing options...
Tony s Posted June 10 Share Posted June 10 (edited) Should work very well. What you’ve done is create a kind of reverse box filter. Where the sponge and bio media go inside a plastic box underneath the uplift tube of a sponge. I liked Bentley’s take on the good and bad of boxes. But if you didn’t know about these before, very cleverly crafted! Edited June 10 by Tony s 1 Link to comment Share on other sites More sharing options...
