    I recently changed my old gravel to a mix of clay, laterite, JBL florpol, peat, flourite sand and JBL manado. When added the flourite it smelled bad and thats when i realised my cat had been urinating  in it. I tried to get as much as i could out then carried on with the rest of the new gravel. After i finished i took an ammonia reading of 4.9 ppm. I did a water change and brought it down th 2.4ppm (still very high) but by the next day it was back to 4.9. I tested NO2 the last couple days and it has been at 0.1 or there abouts. I tested Nitrates and found they were present but I dont know how much as i lost the evaluation sheet. Before this i had never had problems with ammonia. So should I plant the tank back up to absorb the ammonia that is leaching or is my tank going through some sort of cycle?

    Thanks.

    Just let it cycle, maybe add some bacterial cultures to help it along, then do some water changes, be fine.

    The tank should already have cycled as it has been running for over a year i just changed the substrate. Also Im getting very low levels of nitrite as well as a decent level of nitrate which is a sign of a cycled tank right?

    By replacing the substrate you’ve removed a lot of active nitrifying surfaces and added an ammonia source, so everything has to play catch-up. The nitrate reading you’re getting may have already been present (?), or could be a sign that the system is kicking back in. If I remember correctly high levels of Ammonia are toxic to the bacteria that break down nitrite, so they could have taken a knocking which would mean a lag.

    Ok I see. The nitrates have either leached out with the Ammonia or was produced by bacteria as I essentially did a 100% water change and don’t worry about the fish they’re in a “temporary holding tank” but would like to get them back in the tank as soon as possible. So should I add some plants to help absorb any of the remaining ammonia still to leach out into the water column or leave it be?

    I wouldn’t say that plants will take up Ammonia enough to really make a difference if levels are high enough to pose a problem to start with.

    Ok so it really doesnt matter what I do in terms of plants. Could I still add them as the tank would be a better environment for them than the dark bucket or will high levels of ammonia harm the plants? I could probably guess that my Crypt would melt.

    Just tested Ammonia twice and it came back at 0.0 or pretty close to it😮

    Nitrite is now through the roof with a reading of 3.3 ppm or higher:(
