Re: [KOI 969] ammonia, nitrite, nitrate
[In reply to]
Every day, I check ammonia, nitrite and nitrate. Ammonia is 0 but nitrite is less than 0.25. Nitrate is 0 Iím still changing the water in daily basis add salt. But itís temporary solution since I have ammonia / nitrite. I agree, with you that the filter which Iím using doesnít work fine. Really, Iím going to buy anther filter, because I do not want to lose my fish.
From your water parameter is not possible. Why, here is the reason :
1. new pond WITHOUT biological filtration ----> nitrite and nitrate should be 0, unless your water source already contain nitrite and nitrate. But ammonia should at least > 1 ppm, no matter how much water you change. Even if you change water 100%, ammonia should rise in matter of hours. Ammonia > 0; nitrite = 0 or <0,3 ; nitrate = 0
2. New pond WITH biological filtration ---> Ammonia will rise, some converted to nitrite (that's why some water changes is needed to balance your pond water) by nitrosomonas bacteria, which usually colonized faster. Ammonia level should be dropping since some ammonia converted to nitrite. After nitrite begin to rise, nitrobacter bacteria will colonize and convert nitrite to nitrate. And slowly, after all the bacteria growth to its potential (depend on biological filtration media use), ammonia will drop to 0, since all ammonia converted to nitrite. So is nitrite convert to nitrate. At early stage Ammonia > 1 ; nitrite = 0 or <0,3 ; nitrate = 0 (same like without filtration). After nitrosomonas & nitrobacter start to colonize Ammonia > 1 ; nitrite > 0,3 ; nitrate > 0. And after filter mature Ammonia = 1 ; nitrite <0,3 ; nitrate > 0.
Your parameter show a impossible which i may not encounter, unless there is NO FISH inside the pond. My suggestion is your should try to BUY another brand of tester. What tester do you use currently ? Also read the instruction manual carefully, since different brand have different DROP in reaction chamber tube.
