Hi, i was wondering if someon could tell me, would a vectron uv25 be too strong for my 100g, as they are rated for 125g tanks. And the next size down is rated for 50g tanks so woudd it cause any harm to my water quality or fish? Or is there any other UV sterilizer that anyone wouold reccomend? Ive heard about that Green killing machine, or should i just stick with the vecton? Its juts that my water is not the clearest and has lots of tiny microscopic organisms floating in the water, and io am starting to get green water Help appreciated.
