Hi everyone, new here and to the hobby. I've got a question about my tank, it's been running for about 6 weeks now, and it seems i've got some brown diatoms blooming, i understand that this is common at the end of the cycling process. is there anything i can get that will eat it? also i was wondering about moon lighting, is it possible to use a black light? i keep on getting mixed answers about it, any help will be appreciated.
