undergravel

  1. Aquatic Plants, Ponds & Water Gardens
    Hey guys, I'm setting up a 29g FW tank and I'm planning powered under-gravel filtration. I'd like to use some aquatic plant substrate like this, but I want to make sure that it won't clog up the under-gravel flow. Will water still filter through it and get to the pumps underneath? or is it too...
