Bio Wheel filter too strong? Is there a trick

Hello all! I have a mini bow 7 gallon, and got a bio wheel 100 filter for it......the current seems to be pretty strong, and I don't want to risk stressing my fish out.

I have it filled with some real plants, but aren't that tall. I heard you can grow some tall plants there to break up the current....but was curious if anyone knows any other tricks? Thanks so much!
 
I have a betta in the tank.....and I heard that they were ify on the subject with filters....like some cared and other didn't.....so I wanted to make it the least amount of current as possible.


I have it turned off now until I played around with it. When it was on he was swiming around and didn't seem to miffed, but just wanted to make sure.
 
If he's swimming around without any problems (eg. the current pushes him around), then leave it the way it is. If not, use the prefilter suggestion to slow the flow.
 
Yea he seems like he's swimming ok, but then went he stops, it does seem like he'll go in that direction with the flow.......


I'm not familiar with a prefilter. Is there any specific way I could set it up
 
thats a pretty strong power filter for a mini 7 gallon, i would put some plants near the intake, looks better plus your fish won't get sucked agaisnt the powerful intake valve!
 
To put a prefilter in the Bio-Wheels, just shove a piece of sponge (you are going to want it to be pretty coarse, the 100s aren't that strong) up into the instake tube. I tried this with a standard fluval sponge and it flowed so slowly that I had to take it out. The other thing you can do to slow the flow rate down a little is put a lot of sponges in the media slot instead of the sponge/carbon filter packs. Thats what I do. Just make the sponges don't hit the wheel and keep them from spinning.

Also, a 100 isn't anywhere near powerful enough to suck fish in or anything. It is meant for a 10 gallon, so a 7 gallon isn't that much of a difference.

thats true, i forgot I used to own a 100 for my 10 gal

but its made for 20 gallon tanks as well
 
sponge up the intake tube is a good idea. I have a mini biowheel on a 5 gallon bow, and had the same issue. I have an extra piece of sponge in the media slot and have rigged up a "basket" of a piece of some nylons - helps to catch and slow the flow. I think Ill try the sponge/intake tube trick, my nylon basket is a bit odd!
