    Eheim filter flow ratings?

    That’s what I said earlier. ;) Canister filters like the Eheim Classic have been around for decades and the information provided by the manufacturers doesn’t seem to have put people off buying them over the past 30 or 40 years! The classic must be the longest selling canister out there and...

    Eheim filter flow ratings?

    I disagree. If you check the manual, EHeim and most other manufacturers state the pump output, the maximum head and recommended aquarium size. If you find this information useless I suggest you’re in the minority. It’s almost certainly a helpful starting point for most buyers. What is pointless...

    The valve nearest the thermostat as you say doesn’t have a TRV. It should though have a normal valve for balancing the system so you should be able to turn it down. The adjuster is normally under a small plastic cap.

    Eheim filter flow ratings?

    As I understand it the quoted throughput is under ideal test conditions with no media in the filter. Obviously manufacturers can’t predict what media you’re going to use or the location of the filter and hose lengths etc. If you actually run a clean filter without media you’ll find the figures...

    Media Basket

    Actually my mistake, thinking about it some more I’m not sure there is any bypass. The coarse foams at the bottom are doing virtually nothing whilst the fine foam is absorbing as much detritus as it can then letting the excess through into the bio media. My first experiment next time I do a...

    Why are filters not more user-friendly?

    Aesthetics are another issue. I was after a small external to sit next to a Nano and there were a couple that would do the job but so ugly. In some ways, for me at least, the more simple the design the more attractive. Trying to “stylise” some of these products have been a failure in my view:

    Yes, media bags are useful. I actually bought some Sera Siporax and it came in a mesh bag ready to be dropped into a filter. I’ve not actually used it yet so I’ll take a picture. Edit: here it is, 500 ml Siporax. As you can see it’s a very open mesh so won’t interrupt water flow like perhaps...
