Today was a big tank cleaning day and I completely cleaned out my filter (eheim pro 3 2075). The last time I cleaned the filter was 01/01/15.
Tank is 10 months old and each time I clean the filter it looks pretty dirty. My question is is this normal to be this dirty? It kind of looks like dust more then fish waste and such.
I made the mistake of not rinsing my safe t sorb substrate when I first setup the tank and I feel this has been a major contributor to the amount of crap in the filter, thoughts?
Maybe its about cleaning the filter more often, like bi weekly instead of monthly. Flow never seems to decrease though.
here are some pics from today to give you an idea of what I am talking about.
All this stuff comes off everything very easily. I also replace the poly fill each filter clean with fresh material.
My other question is regarding air trapped inside the filter. I have a hydor in-line heater and the way I have to run my hoses it seems like it is hard to get all the air out. Anyhow, I have it up and running but its making a fair bit of squeaking type noises as the air is being pushed out. Is this going to negatively effect my filter? will all the air eventually be pushed from the system? I am still having good flow from the spray bar while all these bubbles are being pushed through so I am not concerned about that. Mostly concerned for the equipment itself.
I never had issues prior to using the hydor heater either.
Here is the tank after the water change and filter clean, I also removed the background (i like it better without it).
