I have a code01 error. I have recalibrated my ph probe but the error persists. I want to replace the probe. But I need to know what the head type and size is if the screws holding the back panel on. Does anyone know?

Are you not able to see the screws?

HOW IMPORTANT ARE FISH TO MAKING A REEF TANK FEEL COMPLETE?

Essential! A reef needs fish movement and personality

Very important, but one or two fish may be enough

Optional... a coral-only reef can feel completely finished

I actually prefer a coral-and-invertebrate-only system

It depends on the tank’s size, style, or purpose

I’ve kept a fishless reef (details in the comments)

Well...it's complicated... (answer in the comments)
