Ok so i recently added a new filter to my aquarium and I decided to utilize Tetra Safe Start to give it a jump start in the cycling process. I have a second filter as well with this tank that is fully cycled but switched from a basic community tank to a overcrowded cichlid tank and wanted the extra filtration. Both of the filters have UV lights which I shut off to add in the TSS. My question is if anyone knows how long I need to wait before I can turn them back on? I ask because I am noticing some brown algae that I am fairly certain is diatomes. Thank you for your help.
