I am occasionally having problems with parasites as my tsn only eats live. Considering a vortex diatom XL for occasionally cleaning tank and a jebo 36 watt sterilizer. The jebo comes with a pump and seems the simplest and cheapest. Does anyone have experience with this UV sterilizer or jebo in general? Also the jebo is listed to sterilize 180 gallons and i have a 210, is this okay. Any advice would be greatly appreciated.
