i'm setting up my 100 gal and was wondering how many and what sized heaters to use it will be in my shed and i live in the uk in the winters i could add another heater to keep the heat up
most ppl will say to use 2 heaters in case 1 fails so if you go that route you could use 2 200w heaters but if you decide to go with only 1 I suggest you get a minimum 300w or larger.
