Canister filter flow issues
I've been using my Eheim 2232 for the pass 3 months. I'm currently having issues on flow. I'm using lily pipes that I got on [Ebay Link Removed] When I first bought them, the flow was fine and I could see that swirly vortex. But now, the flow is so low that it doesn't do that and I can barely see plants swaying. I cleaned my filter last month, but I didn't rinse the pads. I rinsed the mechanical filtration with the tank water from the water change, but I didn't really rinse the pads that finely. My question is, which pads do I clean/replace and how do I go about doing that? Should I just take the pads and shake them rigorously in the tank water? Of course that water would be in a 5 gallon bucket, but is that all?
My tubes are also a little dirty, but I don't think it would hinder my flow that much.
RANDOM: My s. repens is melting. I dose excel and iron daily and have a schedule for trace, potassium, phosphorous, and flourish. I think it's because of my decreased filter flow and consequently the [censored][censored][censored][censored]ty water circulation that results from that. Would purchasing a small powerhead help that?
