UV sterilization

[Napoliandy]

Hi
I’m looking to get a uv sterilizer for my tank. I have a 37 gallon with 10 gallon sump. My return pump is a jebao dcp 4000. I’m researching and trying to understand how to make my choice but I’m a little confused because a lot of them are showing gph lower than what my pump is. I’m not looking to spend a bundle. Does anyone have any suggestions for a pump that will help with algae dinos cyano.
I would appreciate any input you have.
thanks

You would use a ball valve and T it.


However, cyano and dinos come about because 0 nitrate (cyano) and 0 phosphate (dino). Consider saving money and dosing those.
