You can use both. The trick to UV is matching flow rate to wattage. If you have a lower watt bulb (like a 9W), you need much slower flow past it to kill the same amount as the 25W. Flow also needs to slow down with age of the bulb. After 6 months, you're only getting about 50% effective killing from the UV.

This was going to be my question. How old are the bulbs?

If they are pretty old and need to be replaced, it wouldn't be worth it to set both sterilizers up with replacing them.
