Yes I think so
Light : Maxspect jump (not sure how to spell it)
Heater: got it with the fish tank so I’m not sure
Filter: same situation as the heater (thinking I mag need a new one)
I can’t remember my latest parameters so I’m going to test again tomorrow or the day after if I don’t have time
These are all critical components. Do you have a sump or some other type of filtration? Protein skimmer? What does your maintenance schedule look like?
