Two of the best ever pieces of advice from AAP were the pre-filter (sponge filter) for my canister filter and the idea of an Fluidized Sand Bed filter afterwards. Only after some experience with this setup,. I made some changes, namely I isolated the FSB by means of two Eheim Quick Disconnects, so that I can easily take it off line for maintenance, but especially also for startup. For I have now experienced several times that it is very easy when you are priming the Canister filter with the FSB inline that sand ends up getting sucked into the inlet tube.
In short, my conclusion is that after maintenance, I restart the canister first (FilstarXP-s) fisrt, with the FSB disconnected. Once the canister is flowing well, I briefly unplug it, and bring the FSB back in-line.
That solves the problem. The Filstar is a lot more convenient with its quick disconnect feature, which I did not have on the previous canister (
Meanwhile, I am somethings not sure how much sand you need in those FSBs... I tend to just wash the sand and reuse it, but even so there is always some loss. In my 600F FSB, I filled the sand to about 1" below the min line and at that it seems the sand is undulating between min and max.
