My Eheim Experience 350 seems to vary in output during the day. I don’t like this unstable flow as I want to keep my co2 and flow stable during the day.
I observed that the surface ripple changes between ‘normal’ and very intense (the surface ripple becomes much much stronger not a little bit).
I would like to hear your opinions about possible variables that could have effect on the output of the filter. So I have a 'complete' list to troubleshoot.
I troubleshooted a little bit and did the following:
* Make sure the inflow isn’t restricted with leaves.
* Changed the amount my inflow skimmer will suck in so it doesn't suck a lot of air in. When I move the filter a bit I don't hear any air that escapes the filter.
* Cleaned the filtermedia
* Cleaned the Impeller
* Cleaned the filter hoses
* Changed the O-rings for the filter media baskets
* I don't run my filter on Full output it's too much. Around half open. But according to Eheim there should be no problem tweaking the build in valves as long it is on the output. The inflow valve is fully open.
The filter is around 3,5 years old. Could the Impeller be damaged and cause this problem? Any other parts that could have effect on my problem?
The hoses aren't extremely 'long' just next to the tank.
As I can't hear any air escaping when moving the filter a bit can I assume to rule out that the connections of the hoses, inflow, outflow and 90 degree pvc parts don't suck in any air? I don't have any leaks.
Let me know what you think!
