Is it only Balancing input C:N ratio, Promoting suspended-growth nitrification or any other management practices.
Removing the sludge from the pond is also very impotent. Siphoning the sludge by central drain, aeration and arranging them correctly will help to water circulation and accumulation of the sludge in central of the pond.
meaure ammonia, pH and Do daily to maintain the desidre water quality properties. Cleanig watre form uneated feed ,m siphoning the excreta by the the systeme used, Balancing the C:N ratio by adding carbohydrate such as starch and inoculating N-fixing bacteria. Mmaintaining high DO levels in the sysem to convert toxic ammonia into less harmful products like nitrite and nitrate
SIMPLE............... ADD SUFFICIENT CARBON SOURCE ... FOLLOW THE AMMONIA LEVELS TILL IT BECOME ZERO OR NEAR ZERO ..
Control C:N ratio, Control floc density with clarification, probiotic use, ionic balance and, in some cases, water treatment through an nitrifying system, apart from the culture.tanks.
Thank you very much for this nice question. To control the ammonia in BFT system, we should take the followings initiatives
1. Add a biofloc inoculumn to enhance ammonia removal when start BFT study
2. Appropriate C:N ratios
3. Simple carbon sources
4. Optimum floc volumes, higher floc volume may increase some ammonia (I saw in my one experiment)
5. Addapt the optimum feeding rate
6 Remove the sludges when necessary
7. Clarification method can be applied
8. pH should be stable and pH correction methods should be follow
9. Ensure the suitable DO levels
10. Be aware on decayed biofloc, sometimes biofloc can be aggregated with bad smell and floating the tank surface, this biofloc also increase ammonia due to floc microorganisms collapse/mortality
You can change the water in a frequent way and also use proper amount of feed for fish.
1. Maintain C:N ratio
2. Remove sludge from the pond
3. Vertical aeration is required
A combination of factors favours good bioflock development. C:N ratio is most important among them. Other factors are total solids concentration, type of bacteria inoculam given into the culture system and probiotics bacteria developed and microbial Colonies developed.
