I am cyclocya 20long with one platy (who may be pregnant) and 2 snails. We recently switched from a 10 to the 20. I also just added some Anubias and driftwood last night. I had been reading ammonia at 1 and my nitrates went down to 0. I have never measured nitrites. I recently started using prime and I put 6 drops in each 2.5 gallon bucket when I do the water change and the rest of the 2 ml in the tank. I tested the water today and the Ammonia was 1, nitrites 0 and nitrates back up to 5! I bought stability yesterday. I just did the water change and did the prime in each bucket. Would you add stability or just keep letting it do it's thing since my nitrates are back?
