So my canister filter is putting out a relatively strong flow threw the output nozzle and was blasting my plants at the opposite side of the tank in the back left corner(output is back right). So to slow it down some, I put one of those filter inlet sock things on it to reduce flow and added a small piece of driftwood in front of the outlet to reduce flow. This is now creating more surface agitation. I know surface agitation isn’t great for wanted to keep the Co2 I’m injecting to stay in the water and not escape from the gas exchange. So how much surface agitation is too much?? Also my filter did come with a spray bar which would definitely reduce the flow, the only problem I found with it, is that when installed the spray bar is positioned much closer to the front glass and the water comes out from the middle to middle front (along the right side , not the middle of the front glass)of the tank and sprays across the tank to the left which messes my flow pattern for the tank and co2 spread. I would like to have my flow start from back right corner across to the back left corner hit side glass move to front left corner (where my co2 infuser and small power head are) then back across the front glass to front right corner and so on. So is that flow pattern a good one? OR will the flow pattern of using the spray bar be okay? Which is more like having the water goes across the tank from right to left and then it hits glass and kind of goes back across to the right on both the back and front glass. A more side to side flow VS a circular flow. I feel like I’m just rambling now...hahaha. Basically I need less flow for my plants, but don’t want to screw up my flow pattern..and also how much agitation should I have at the surface?! Right now it’s just enough to cause the water to bulge a little bit and shimmer the light but doesn’t technically break the surface and form any bubbles. Sorry for the all over the place rambling..please help!
