question about cycling

  1. buck@ekan Initiate Member

    Got problem need to solve during cycling. 19L tank, declorinated freshwater, hang type pump c/w biofilter media + carbon.

    cycling method: "add daily" as described.

    Added 4 drops pure ammonia (25%) based on the calculator. after 8 days, Ammonia hovering around 8ppm, pH 7.8, NitrIte start showing 1.0 - 2.0 reading (API test kit), NitrAte at 10-20. Due to evaporation (lost about 30% water) I added declorinated water. For next 3-4 days, all indation seems to maintain.

    Then pH drops to 6? Temperature was around 27C. Few days later, NitrAte drops to 0, NitrIte also 0, Ammonia around 2-4ppm.

    Did I messed up? How to fix it? Start all over?

    Need advice.

    Hello Buck and Welcome to Fish Lore. You may find the above link to another thread on the same subject helpful. I don't have personal experience with this method myself.
    I'm sure you'll get some more responses.

    With a pH level as low as 6 it may delay your cycle. Too, with an ammonia reading as high as 8, it may be too high and the good bacteria can't get control. I'm thinking a water change may be in order but let's get some more responses first!
    Best of luck!
