Hi!!
I think cleaning routine is something you have to ajust and discover by yourself, watching how clean your
tank stays and for how long.
I would really recomend you a siphon, even if you have a bare tank. If you dont have one, I guess you
would do water changes taking water out with a glass or a little bucket? The siphon will take out the water and waste, as you can siphon areas of your choice.
Im a bit of a maniac about cleaning routine.
For poo, if it is fresh, I take it out with a plastic fork and a little net. If it isnt, the turkey baster works just fine.
In cleaning time, I take out my axies and turn on a little pump to help the filter take some particles I was unable to take out with the siphon. I let the water run for a while, and then clean the filter sponge with tank´s water.
I hope this helps
