I’m trying to cycle a 10 gal fish tank. I have been adding your biological booster for a month now and nothing is happening. The ammonia is holding steady at .5 ppm and I’m not seeing any nitrites. Is there a way I can test to see if there are actually live bacteria in the booster. I’ve checked everything else I can think of.

Unless you submit a water sample for culture or microscopic exam, you won't be able to determine if there are beneficial bacteria. With ammonia at the current level, there are bacterial populations. It takes time and patience to cycle a tank, sometimes up to 6-8 weeks. I'm not a fan of the "boosters", since you don't know how long they have been on the shelf or if the biologics are even active. Sprinkle some flake food in the tank and allow nature to run its course. The bacteria will feed off the flakes and populate the tank. Perform a 10-15% water change using conditioned water as needed during cycling.
