I’m having a heck of a time keeping the sand in my 75 gal planted tank clean. It is a finer sand. I’ve used 2 different size pythons but end up pulling more water out then debris…I’ve tried the hover and swirl method but the crap just swirls around and then fall out the end when I move the tube. I’d really rather not change the substrate since I have no where to move the contents of the tank. Should I try a different brand of vac, electric one or whatever? Could I add a couple bags of pebble gravel to make it heavier?? I’m at a loss..
