What about using a spray bar in reverse? That way water is brought

the spray bar hole as the suction would be reduced drastically) get
sucked into the filter? Also would be good for weak / ill fish so
they don't get caught in the filter either?

Did you check the EHEIM Pre-Filter 400462?
It has a large open sponge surface of maybe 8cm diameter and
therefore the velocity of the water in the intake is so slow that
really any fish can easily escape. At least as long as the fish is
still moving at all.

Thanks jue! I will check it out. I am very impressed with the newer eheim
canister filters - I like the idea of absolutely no bypass. I will get one
one of these years but I need to wait until I save up some money first
(eheim's are out of my financial range right now but that might change
relatively soon, I love my fluval msfs, but even they are out of my range as
far as buying a backup goes) thanks and later!
