Here is a link to an Actual Picture of the res i am Using
Thats a picture of my current res. and hopefully you can interprete from my paint drawn picture above what i am attempting. In terms of porous material could you list some. I have available sponges, the air filter from the from of my Lian-Li PC-62 which is like a Air conditioner filter you can see through it. Haven't been able to think of anything else yet. Before i go and lodge these pieces into my res. i am thinking that they will get pushed to the bottom but that may not be bad if it doesn't hinder flow to much or should i leave an air-space near the top of the res. for the sponge or whatever to float on hopefully maintaining its bouyence. More suggestions welcome i will be trying stuff all day today.
