Please help me understand wattage in uv sterilizers.
UV Sterilizer : I have two of them. A 120 watt Aqua UV. It has 3 - 40 watt bulbs. It’s big and takes up a lot of space. Also have an Ice Cap UV with 1- 90 watt bulb. My question is which one is really better? Wouldn’t a single 90 watt bulb be more powerful than 3 40watts? Yes 3 X 40 is 120watts but I mean the water is still just going thru 40watts but 3 times so is it really 120 watts strength bulb vs one 90 watt bulb? Will be going on my new 270 gallon tank.
