Maybe you wont like this, but this is what I did. I did not have a siphon handy to clean out my tank, so i got creative! For this u need a HOB filter that has a tube sucking up the water etc. Well take the tube (tube size depending on how big the tube on the filter is) and put it over the filter tube. The filter will suck the water through the tube and u can manuever the tube to where the poo or anything else tha needs to be siphoned! thats it! i dont see anything bad about this except the filter media might need to be changed sooner.
