Help me fix my flow

[Slick Fork]

I think if I do replace one, it will be a tunze or vortech. Not really keen on the knockoffs but that's a debate for another thread!

Realized I didn't answer your question myka, I'm not really sure that flow is the cause of my problems, I'm sure my nutrients are the cause of the snotty hair algae that took root. I do feel that it could be better and that improving the flow will help the slow crawl back to a nice looking tank.
