Usually people get a powerhead to supplement the filter's flow. Place it near the filter's output and it should help a lot. Add one rated at about 500 gallons per hour so the flow is about 10x tank capacity.
Thanks a lot. I went into the pet store today and decided to order some online since they are literally less than half the price online. -__-
I still want to get the the canister filter a spray bar. Where would I go to buy one? Anyone know? Or is the DIY route the easiest?
