We're new to owning fish. We have a 25l tank which we did all the water testing/ cycling with before we added guppies with the permission of the pet shop.
I need to clean the gravel with the water change but I just can't get the gravel cleaner to work. I've watched lots of YouTube videos and no matter which way I do it I just can't get it to pump any of the water out. Any help or tips would be massively appreciated..
