Yea all 3 tanks have a filter......2 are the hexagon led tanks that petco sells.....I actually dampened the flow with filter floss stuffed in the the filter intake vents. As for the fluval, the current to the filter doesnt seem to bother him much but the out take flow that sends water back into the tank sometimes throws him. To fix this I put 2 thick foxtail plants in front of it and it seemed to stop him getting thrown around. Its been like this for 2 or so months and everything was fine until early this week. Now he looks all beat up and the top fin is barely connected to his body.
I had an idea to fix the fluval out take problem even more but I haven't been able to find an extra tubing part since I haven't found one used or some one selling one for parts.
