My tank is 140 gallons and I was thinking of getting a UV Sterilizer to avoid anything bad coming in. But I don't want to spend 300 + on it. I did find a sterilizer for 75 gallons https://www.bulkreefsupply.com/15-w...lizer-with-hanger-spout-aqua-ultraviolet.html for a bit less! is something better then nothing!? its hang over the back style and it would work for me! what are your thoughts?
