Was unsuccessfully fighting dinos for a few weeks. Manually siphoning every day and increasing nutrient input, but no progress.
Was debating whether I wanted to try the Dr. Tim’s Waste Away method or UV to fix it.
Decided to go with UV since it’s a very affordable solution for a nano tank and I didn’t want to have to do the multi day blackout with Waste Away. Got the Auqa Shield UV Sterilizer Desktop. Took a couple minutes to “install” and it got rid of 95% of dinos overnight. It was probably 48 hours until I couldn’t see any leftover dinos. Let the UV run for 4 days just to be sure and now have had the UV offline for 3 days. Maybe too early to tell, but I think the tank is “cured”. $50 well spent.
Next problem — solve this algae issue.
