I've got a lifegard fb300 on my 55 gallon semi-aggressive community tank. I was driving it with a Fluval 205 canister, but it was not generating enough flow to do a good job of keeping the sand bed fluidized. I upgraded to a Fluval 306 which I assumed would make a large difference. The improvement was barely noticeable. I was considering upgrading again to a 406, but I don't want to spend that much and have it not work either.
It seems like the canister's impeller design doesn't cope well with the back pressure from the sand bed and so the flow rate drops well below the normal rated output.
Does anyone have any experience with an fb300 and how much "rated" flow it will take to keep it working properly?
Thanks
Adam
