I have this filter in my new tank set up and have had 3 zebra danios in the tank for 6 days now, ive been waiting for the ammonia levels to peak and nothing has happened, i then found out that the filter media cartridge has Zeolite in.
Im worried this will slow down or even stop my new tank cycling, has anyone used this filter or has any advice on how to proceed??
Hi, I have that filter and always remove the baskets with carbon/zeolite in to add sponges/ceramic noodles to the space left as it gives a better surface area for bacteria to grow but I always add mature filter sponge to all my new filters so I never have to cycle any tanks as I run quite a few, I would remove the baskets and add some filter floss or sponges and then keep a very close eye on the ammonia readings you should find they will probably rise then you will need to keep up with the water changes, which test kit are you using at the mo?
Whilst this is true, I use zeolite as last stage filtration in all of my planted tanks to prevent algae from blooming.
However, eventually when the zeolite/carbon block becomes saturated, it will have a nice amount of surface area for bacteria to grow on, although not as much as fine filter floss would.
