I have just purchaced a secod hand uv sterilizer which came with no instruction manual so i have a couple of questions
its a vecton ultraviolet sterelizer the old type, it says its 11-13 watt and for 230 litres my tanks only 125(marine reef-ish), is this ok or is it possible to over uv?
My eternal filter which it is going on is a fluval 304 are these compatable?
This may seem like a stupid question but which way round does it go? as in which way does the water flow in and also which way is the bulb incerted? i assume that it dosent matter. i just dont want to make any big mistakes.
and is there anything else i shoud know? i understand that directly looking ta the bulb is damaging to the eyes but the way its made seems to prevent you from accidenty blinding yourself.
thanks for any replys

. The largest concern with UV sterilizers (aside from not looking directly at the bulb) is flowrate. They have a specific flowrate they're designed for. Too slow and you don't move enough water to be effective. Too fast and parasites/bacteria/etc don't spend enough time in front of the UV light and only come out with a mild tan instead of impotent
