Biological filtration

Hello all you thinkers out there! I’ve just gone through the “Free DIY floading bead filter parts “with great interest as usually.



I can’t stop wondering when my bacteria notice that it has left the filter and should stop transforming (performing). It feels funny but I often get marvellous readings when I turbo charge the filter. This is done with bleeding in from 50mm pipe in biological start section and accepting really low water levels in these chambers. Is then taking +2 x 10 t/h through filters that is designed (old thumb rules) for max 10 t/h.



PS! One 110mm is used normal to this filter set.



Same do occur around this time every year in regard to flow through water change. As we move our dear ones indoors we have a rather high flow through. We are now moving up to local indoors summer and have past 21°C (will stabilise and hold for 8-12 weeks) at 26-28°C) We have after trial and error found that optimum removal and conditions when filter is in good order is at relatively low follow-through? This is specially evident indoors as we normally have basis feed of shrimp and salmon (only reduced weight of feed) in the cold period until fairly high temperatures are maintain (~22-23°C).



Thoughts, input & and “harassment” are welcome as brain food in this limbo time.
