Do I leave it On? :0

hello, everyone
I havent got any fish yet but when I do I am interested to knoe what you do at night time.
I know you can turn off the light at night (correct me if i am wrong)
But can u swtich the filter pump and heater off too
or do they have to be on all the time?

Lights off at night but definitely not the filter & heater. They need to be on all the time.
I have my lights on from around 10am-10pm

Filter and heat no!!! Lights can go off otherwise you might find you get algae.

Filter and heater both need to be kept on to maintain the filter bacteria population (filter) and the water temperature (heater). Depending on whether or not you have plants will determine how long the lights need to be on for. In my planted tanks, I have the lights on for 8 hours a day but in the non-planted ones, just for two hours in the evening to see the fish.

Ok then, Thank you all!
