So I'm thinking of investing in a powerhead for my 60G moderately planted tank. I have a Fluval 404 canister filter that says it puts out about 340gph, but I'm getting dead spots on the bottom of my tank.
There are two spots in particular on the substrate in the middle of my tank that accumulate a lot of detritus. I'm wondering if I do buy a powerhead, what kind of flow rate should I be looking for? Ideally I was thinking like a 200-300gph powerhead placed on the mid-lower part of my tank to get some more flow nearer to the substrate.
The problem is, it seems that the more powerful powerheads are FAR cheaper. Go figure. A 240gph powerhead I found on Amazon was ~$60 while a 2-pack of 528gph ones was ~$18. For that price, I would just buy the 528gph ones. But it seems to me that even one of those 528s would be too much flow for my tank - would it not?
