jlk said:Once a week gravel vac is fine when you do a pwc. If you do more frequent pwcs, you can run the vac over the surface to suck up any large debris. I wouldnt about your filter media quite yet unless its so clogged water is not flowing through it. I would honestly wait a few more wks & then you can swish the media once a week in a bucket of tank water. If you have more than one filter, i would alternate the swishing to 1 set of media one week & the other set the following week. These are just general guidelines- you will figure out what works best for you over time!
I won't destroy or harm the beneficial bacteria by doing a gravel vacuum soon ? And thanks for the reply JIK
