Thats perfectly fine. You probably dont need the two bottom rubberbands. They get decrepit when constantly submerged, so they may break.
As long as it wont knock the fish around (like if he swims under it) or push him hard away or down, its fine!
Eventually, it will slow and not need a baffle. Mine did in less than 8 months.
do you mean the filter motor gets weaker or does it get accumilation to slow down the flow over time? i put the thin aquarium foam (doubled up) that held anacharis together and put it on my 2.5g filter, it runs like a leaky faucet and it still seems to create a flow (a floating silk plant leaf is forced to the bottom). at the moment its a constant 2-3mm wide section that flows into the tank.
Sick of you? Nooo. Im the one perusing YOU! Haha :D I dont mind or anything, ask away. I liked my 5 hex, and cant wait to put it back into commission. Tomorrow, its gonna be a plant tank for a water sprite that is literally as long as my arm, dang DX
Now that I finally have a new buddy (squee! pictures in the picture forum), I'm still not sure if the baffle is doing its job or not. He isn't getting pushed down violently, but I still think he's being pushed around somewhat. Either that, or it's just him being spazzy.
Time will tell I guess. I'll keep an eye on it and see if I might need do do anything else.
EDIT: I went and had a closer look - it seems that when I replaced the hood etc., the baffle got knocked askew. I'm going to wait a few hours before I go in and mess with it. He seems to be having a fun time, though. I mean...if he really didn't like it, wouldn't he just go to the other side of the tank where there's no real flow?
