hällt forever!

Must now also times my mustard to give. The filter is with me in the assembly, from top: coarse / fine blue cotton fleece / Nitrax / Blue. and besides the cotton flow is there nix cleaned and not before one year! to say that the Nitrax filter your pool "vaccination" the bacteria are then splashing around in all other filter sponges, so fingers away with ausspühlen,
wechsellt only the cotton filter, but let the other "biotope" in peace, live in billions of creatures that your water filter, this spühlt her out when cleaning the sponges.
When the year is out, I start from below, in the 14 days rytmuss the sponges to replace with new ones, so the filter basket out, replace the bottom with a new one, and then wait of 14 days, until the middle one drann, and at the end of Green, but nothing please wash! And never in the week where you have exchanged a sponge to the filter, make a water wech sell !!!! And do not forget to replace the cotton Fliessestrich up regularly, then you vermulmen not the sponges! And so you always have a clean pool! Übriegens the black carbon sponge has to look only for the time a drug removal after any illness something in the filter, after 10 days out with it!
