Firstly, before the water flows through the rest of the cleaning process, EHEIM MECH and EHEIM MECHpro provide high efficiency. EHEIM FIX is the ideal material to use as a separation layer between the mechanical and biological filter media. And for fine filtration at the end, before the water returns into the aquarium, EHEIM SYNTH is the ideal material to use.

Just a quick note to thank you for the great service you have given me and to let you know all the fish arrived safe and alive. I am very happy with them and look forward to dealing with you again in the near future. - Dave P
