Plumbing 2 uv sterilizer's together using 1 pump

[h3fz]

Hi,
I have recently upgraded ny UV sterilizer from a aqua ultraviolet twist 25watt to a 57watt, my question is: can i just add the 25 watt back into the system running off my 57 watt for double exposure? Or is there no point?

I would think it would increase your UV. Just have to replace two bulbs instead of one.
