Buy the SunSun JUP 01 9W UV Sterilizer here: https://goo.gl/GQXRq0
My 29 gallon show tank continued to have an algae bloom so I decided to buy my first uv sterilizer. I bought a SunSun JUP-01 9W UV Sterilizer Submersible Filter Pump (rated for up to 75 gallons). While it was an eyesore and very powerful for my tank, it did a nice job and I hope to only use it when there are algae blooms (don’t plan on making it a permanent fixture. Bought on Ebay and inspected it before I used it.
