None of my canisters have adjustable flow rates- can I change the flow (by adding valves or such) without burning out the motors? The main reason I'd like to do this is because all of my high flow canisters have built in UV lights. I don't know why they put them in the high flow ones and not the smaller low flow, but anyway- if there is something I can do to reduce it so that the uv actually works as a steriliser and not just a clarifier, that would be brilliant
