Right now for the cycle's sake I have the filter (Hagen Elite Mini) on full-blast, which obviously creates a lot of water current. I plan to baffle it with some extra filter foam, but when it is time for acclimate Tom to the tank, should I leave the filter on full blast? Or turn it down to low?
Also, the outside of the air tube on the filter has been gathering some build-up (mold? BB?) at the base where it connects to the filter. I have been wiping it off because it looks gross, but I was wondering if I should be leaving it alone? What is this build-up and is it safe for Tom to be in contact with when I acclimate him?
Last question (for now
)!-- How often should I clean out the filter's internal foam? Does it need to be cleaned after the cycle is fully complete and before I acclimate Tom?
