Karen B. Posted December 21, 2020 Share Posted December 21, 2020 Greetings! I am trying to slow down the flow of both my Aqueon 10 & 20 HOB filter. Both have a prefilter sponge, then a coarse sponge in the left chamber. The right chamber is split in half : aquaclear sponge at the back and bio balls in the front. Then the fall down is stuffed with a fine sponge/floss. I saw the water bottle trick (cut a cylinder off a water bottle and split it horizontally, then place it in the filter to create a half moon and divert the flow) and it seems to work great... until I close the lid. The lid seems to push the plastic a bit too tight and I wonder if that could be dangerous (stop the flow altogether or something?) No lid with a gap with a lid. You can see how tight the plastic is. Is it possible to leave the lid partially opened or can it cause too much water evaporation and the beneficial bacterias could die? If you have any other tips, tricks or advices, I am listening. The tanks also each have a sponge filter. Link to comment Share on other sites More sharing options...
