Hi everyone. I have a Rio 2100 internal power filter in my 55 gallon tank that pumps 690 gph
. It creates quite a current (not too powerful for my fish) which was fine when I had gravel (in fact it did a great job of keeping things off the bottom), but now that I have sand in the tank it causes problems. The sand is settled pretty good, but every time a fish kicks some up it gets caught in the current and quite a bit is getting sucked into the filter.
So, what I was thinking of doing was attaching a long piece of pvc
to the output on the filter and drilling holes in it to release the water in many different areas (hopefully cutting down on the current). My hope is that when sand gets kicked up it will settle before it gets to my filter. I was also going to put a bio sponge on the entire length of the pvc
pipe in hopes that would add to my biological filtration.
So, my questions is, would something like this work/be beneficial at all? Also, one more question. I have a bunch of filter pad, could something like that be used in the same manner as a bio sponge. I know that stuff is meant for mechanical filtration, but it seems to me like it would be a good surface for bacteria. Any advice?
