That’s why I added the snails. I’ll test today and hopefully they produced some waste so it has no ammonia and has nitratesAh, if you meant it was all zeros last night, then a newly set up tank would have all zeros because it's brand new. All you were doing was testing tap water in the tank. Assuming your tap water has all zeros.
You can't risk adding the shrimps until you know the sponge filter has enough bacteria.
