I have a 15 gallon tank which is affected by Fish tb. I have lost 9 danios so far. I came across UV sterilizer treatment while reading an article on mycobateriosis by madam Diana Walstad. I have just installed a DIY UV sterilizer which is used for domestic RO purification of water . I have a 11 w UV lamp . At first I kept the flow rate at 30 gph and still it didnt seem to work.Now I have reduced the flow even further. what would be the correct flow rate of water ?
NOTE : I am willing to run the motor 24/7, with a 1 hr break every 4 hours, since my motor gets heated up . THANKS IN ADVANCE...
