setting up a Fluval Spec 5 and 3 weeks after seeing nitrites, I have seen no progress. Not sure which direction to go...
I'm not using the carbon pouch. I have 2 bio media pouches inside the sponge area. One of the media pouches was sitting in another tank for almost a month before going into the new tank. There is also an airstone in the tank.
I'm using fishless cycle method as seen here. https://www.buildyouraquarium.com/ho...ishless-cycle/
Day 1 using API master test kit ammonia and nitrate are zero and nitrate shows 0 to 5ppm range(out of the tap)
I dose detergent free pure ammonia from Ace Hardware to 4/5 ppm.
On the 3rd day, ammonia was nearly zero and nitrite is up in the 5ppm range, no change in Nitrate
I can dose the ammonia and the next day the test shows at or near zero and the and the nitrite stays around the 5ppm never going down and no spike in the Nitrate. I'm allowing 48 hours in between ammonia doses and I'm only using about a 3 quarters of a ML to go the ammonia level up.
I have not done a water change, I have topped off a couple times due to evaporation.
any suggestions would be greatly appreciated
