Hey all,
I just upgraded filters for my 56g column from 2 fluval U2 to a Fluval 305 canister. I'm wondering if the flow rate is too high or if there's an "optimal" flow rate? The box says 260 GPH (185 GPH filter circulation). Above the outtake, sometimes I'll notice a little water funnel here and there. I have a few stem plants that move a little bit and even though the outflow is towards the top, I've noticed some of my fish staying at the bottom on that side seemingly fighting the current (unless they actually LIKE doing that). There's an adjuster for the filter, but it says not to go below 50%.
The reason I bring this up is because I notice the food moves around a lot more than with the 2 U2s. Granted, the two were submerged quite a bit down the tank, so there didn't seem to be a lot of top current.
As a side question with regards to feeding, should I just unplug the filter so there's no water movement when I feed? I saw on Youtube (I think) about pre-soaking the flake food in a cup and then slowly pouring it in a little at a time. Any thoughts on this? There's still a lot of current moving that food that's now starting to sink faster due to pre-soaking.
I know I got a bit "rambly" (I tend to do that lol). I appreciate the help! Tank specs are fairly up to date.
