Complete newbie! Two questions!
Hi y'all! I wasn't sure if this should go in the lighting section or general, so I went with general.
I'm naming on planting a fluval chi here really soon (low tech) and I haven't a clue what kind of bulb to get! My current plan is to purchase a clip on lamp and direct the light towards the tank as the build in LED is complete crap.
Currently, I've got black sand on the bottom...should I remove that and replace it with a different substrate or will the black sand be okay?
Thank you in advance!
