Hi guys I'm trying to set up my sister's new 29 gal and I wanted to help her seed her tank by putting my old filter media with bb to speed up the cycle. I just bought a new filter pad. So my question is when should I remove the old filter media from my aquarium i currently have my new media with the old one still inside my filter. I have a 55 gal that has been established for a yr
I usually seed new filters and tanks for 3 weeks. I have never tried less time and have never had to go longer.
Thank you so much I've had it for a week so I'll wait for 2 more
